 ## Our Pledge
 
 In the interest of fostering an open and welcoming environment, we as
-contributors and maintainers pledge to making participation in our project and
+contributors and leaders pledge to making participation in our project and
 our community a harassment-free experience for everyone, regardless of age, body
-size, disability, ethnicity, gender identity and expression, level of experience,
-nationality, personal appearance, race, religion, or sexual identity and
-orientation.
+size, disability, ethnicity, gender identity and expression, level or type of
+experience, education, socio-economic status, nationality, personal appearance,
+race, religion, or sexual identity and orientation.
 
 ## Our Standards
 
+We are committed to providing a friendly, safe and welcoming environment for
+all.
+
 Examples of behavior that contributes to creating a positive environment
 include:
 
+* Be kind and courteous to others
 * Using welcoming and inclusive language
 * Being respectful of differing viewpoints and experiences
+* Collaborating with other community members
 * Gracefully accepting constructive criticism
 * Focusing on what is best for the community
 * Showing empathy towards other community members
 
 Examples of unacceptable behavior by participants include:
 
-* The use of sexualized language or imagery and unwelcome sexual attention or
-advances
+* The use of sexualized language or imagery and sexual attention or advances
+* The use of inappropriate images, including in a community member's avatar
+* The use of inappropriate language, including in a community member's nickname
+* Any spamming, flaming, baiting or other attention-stealing behavior
+* Excessive or unwelcome helping; answering outside the scope of the question
+  asked
 * Trolling, insulting/derogatory comments, and personal or political attacks
+* Promoting or spreading disinformation, lies, or conspiracy theories against
+  a person, group, organisation, project, or community
 * Public or private harassment
 * Publishing others' private information, such as a physical or electronic
   address, without explicit permission
-* Other conduct which could reasonably be considered inappropriate in a
-  professional setting
+* Other conduct which could reasonably be considered inappropriate
+
+The goal of the standards and moderation guidelines outlined here is to build
+and maintain a respectful community. We ask that you don’t just aim to be
+"technically unimpeachable", but rather try to be your best self.
+
+We value many things beyond technical expertise, including collaboration and
+supporting others within our community. Providing a positive experience for
+other community members can have a much more significant impact than simply
+providing the correct answer.
 
 ## Our Responsibilities
 
-Project maintainers are responsible for clarifying the standards of acceptable
+Project leaders are responsible for clarifying the standards of acceptable
 behavior and are expected to take appropriate and fair corrective action in
 response to any instances of unacceptable behavior.
 
-Project maintainers have the right and responsibility to remove, edit, or
-reject comments, commits, code, wiki edits, issues, and other contributions
+Project leaders have the right and responsibility to remove, edit, or
+reject messages, comments, commits, code, issues, and other contributions
 that are not aligned to this Code of Conduct, or to ban temporarily or
-permanently any contributor for other behaviors that they deem inappropriate,
-threatening, offensive, or harmful.
+permanently any community member for other behaviors that they deem
+inappropriate, threatening, offensive, or harmful.
+
+## Moderation
+
+Instances of behaviors that violate the Adafruit Community Code of Conduct
+may be reported by any member of the community. Community members are
+encouraged to report these situations, including situations they witness
+involving other community members.
+
+You may report in the following ways:
+
+In any situation, you may send an email to <support@adafruit.com>.
+
+On the Adafruit Discord, you may send an open message from any channel
+to all Community Moderators by tagging @community moderators. You may
+also send an open message from any channel, or a direct message to
+@kattni#1507, @tannewt#4653, @danh#1614, @cater#2442,
+@sommersoft#0222, @Mr. Certainly#0472 or @Andon#8175.
+
+Email and direct message reports will be kept confidential.
+
+In situations on Discord where the issue is particularly egregious, possibly
+illegal, requires immediate action, or violates the Discord terms of service,
+you should also report the message directly to Discord.
+
+These are the steps for upholding our community’s standards of conduct.
+
+1. Any member of the community may report any situation that violates the
+Adafruit Community Code of Conduct. All reports will be reviewed and
+investigated.
+2. If the behavior is an egregious violation, the community member who
+committed the violation may be banned immediately, without warning.
+3. Otherwise, moderators will first respond to such behavior with a warning.
+4. Moderators follow a soft "three strikes" policy - the community member may
+be given another chance, if they are receptive to the warning and change their
+behavior.
+5. If the community member is unreceptive or unreasonable when warned by a
+moderator, or the warning goes unheeded, they may be banned for a first or
+second offense. Repeated offenses will result in the community member being
+banned.
 
 ## Scope
 
+This Code of Conduct and the enforcement policies listed above apply to all
+Adafruit Community venues. This includes but is not limited to any community
+spaces (both public and private), the entire Adafruit Discord server, and
+Adafruit GitHub repositories. Examples of Adafruit Community spaces include
+but are not limited to meet-ups, audio chats on the Adafruit Discord, or
+interaction at a conference.
+
 This Code of Conduct applies both within project spaces and in public spaces
-when an individual is representing the project or its community. Examples of
-representing a project or community include using an official project e-mail
-address, posting via an official social media account, or acting as an appointed
-representative at an online or offline event. Representation of a project may be
-further defined and clarified by project maintainers.
-
-## Enforcement
-
-Instances of abusive, harassing, or otherwise unacceptable behavior may be
-reported by contacting the project team at support@adafruit.com. All
-complaints will be reviewed and investigated and will result in a response that
-is deemed necessary and appropriate to the circumstances. The project team is
-obligated to maintain confidentiality with regard to the reporter of an incident.
-Further details of specific enforcement policies may be posted separately.
-
-Project maintainers who do not follow or enforce the Code of Conduct in good
-faith may face temporary or permanent repercussions as determined by other
-members of the project's leadership.
+when an individual is representing the project or its community. As a community
+member, you are representing our community, and are expected to behave
+accordingly.

+Terminology
+-----------
+
+As our Code of Conduct states, we strive to use "welcoming and inclusive
+language." Whether it is in documentation or in code, the words we use matter.
+This means we disfavor language that due to historical and social context can
+make community members and potential community members feel unwelcome.
+
+There are specific terms to avoid except where technical limitations require it.
+While specific cases may call for other terms, consider using these suggested
+terms first:
+
++--------------------+---------------------+
+| Preferred          | Deprecated          |
++====================+=====================+
+| Main (device)      | :strike:`Master`    |
++--------------------+---------------------+
+| Peripheral         | :strike:`Slave`     |
++--------------------+                     +
+| Sensor             |                     |

+| Denylist           | :strike:`Blacklist` |
++--------------------+---------------------+
+| Allowlist          | :strike:`Whitelist` |
++--------------------+---------------------+
+
+Note that "technical limitations" refers e.g., to the situation where an
+upstream library or URL has to contain those substrings in order to work.
+However, when it comes to documentation and the names of parameters and
+properties in CircuitPython, we will use alternate terms even if this breaks
+tradition with past practice.

 Supported Ports
 ==============================
 
-Adafruit's CircuitPython currently has limited support with a focus on supporting the Atmel SAMD
-and ESP8266.
+CircuitPython supports a number of microcontroller families. Support quality for each varies
+depending on the active contributors for each port.
+
+Adafruit sponsored developers are actively contributing to atmel-samd, mimxrt10xx, nrf and stm
+ports. They also maintain the other ports in order to ensure the boards build. Additional testing
+is limited.

-All of the boards share the same core pin functionality but call pins by
-different names. The table below matches the pin order in
-`the datasheet <http://ww1.microchip.com/downloads/en/DeviceDoc/40001882A.pdf>`_
-and omits the pins only available on the largest package because all supported
-boards use smaller version.

-Here is a table about which pins can do what in CircuitPython terms. However,
-just because something is listed, doesn't mean it will always work. Existing use
-of other pins and functionality will impact your ability to use a pin for your
-desired purpose. For example, only certain combinations of SPI pins will work
-because they use shared hardware internally.

-Setup
------
-
-An ARM compiler is required for the build, along with the associated binary
-utilities.  They can be installed as follows:
-
-- Ubuntu
-
-  .. code-block:: shell
-
-      sudo add-apt-repository ppa:team-gcc-arm-embedded/ppa
-      sudo apt-get install gcc-arm-embedded
-
-- Arch Linux
-
-  .. code-block:: shell
-
-      sudo pacman -S arm-none-eabi-gcc arm-none-eabi-newlib 
-
-For other systems, the `GNU Arm Embedded Toolchain <https://developer.arm.com/open-source/gnu-toolchain/gnu-rm/downloads>`_
-may be available in binary form.
-
-The latest available package from team-gcc-arm-embedded is used to produce the
-binaries shipped by AdaFruit.  Other compiler versions, particularly older
-ones, may not work properly.  In particular, the ``gcc-arm-none-eabi`` package
-in Debian Stretch is too old.
-
-The compiler can be changed using the ``CROSS_COMPILE`` variable when invoking
-``make``.
 
 Building
 --------
 
-Before building the firmware for a given board, there are two additional steps.
-These commands should be executed from the root directory of the repository
-(``circuitpython/``).
-
-1. There are various submodules that reside in different repositories. In order
-   to have these submodules locally, you must pull them into your clone, using:
-
-.. code-block:: shell
-
-   git submodule update --init --recursive
-
-2. The MicroPython cross-compiler must be built; it will be used to pre-compile
-   some of the built-in scripts to bytecode.  The cross-compiler is built and
-   run on the host machine, using:
-
-.. code-block:: shell
-
-    make -C mpy-cross
+For build instructions see this guide: https://learn.adafruit.com/building-circuitpython/
 
 
-Build commands are run from the ``circuitpython/ports/atmel-samd`` directory.
-
-To build for a given board you must specify it by setting ``BOARD``. For example:
-
-.. code-block:: shell
-
-    make BOARD=feather_m0_basic
-
-Board names are the directory names in the `boards <https://github.com/adafruit/circuitpython/tree/master/ports/atmel-samd/boards>`_ folder.
-
-Deploying
+Debugging
 ---------
 
-Arduino Bootloader
-^^^^^^^^^^^^^^^^^^
+For debugging instructions see this guide: https://learn.adafruit.com/debugging-the-samd21-with-gdb
 
-If your board has an existing Arduino bootloader on it then you can use bossac
-to flash MicroPython. First, activate the bootloader. On Adafruit Feathers you
-can double click the reset button and the #13 will fade in and out. Finally,
-run bossac:
-
-    tools/bossac_osx -e -w -v -b -R build-feather_m0_basic/firmware.bin
-
-No Bootloader via GDB
-^^^^^^^^^^^^^^^^^^^^^
-
-This method works for loading MicroPython onto the Arduino Zero via the
-programming port rather than the native USB port.
-
-Note: These instructions are tested on Mac OSX and will vary for different
-platforms.
-
-    openocd -f ~/Library/Arduino15/packages/arduino/hardware/samd/1.6.6/variants/arduino_zero/openocd_scripts/arduino_zero.cfg
-
-In another terminal from ``micropython/atmel-samd``:
-
-    arm-none-eabi-gdb build-arduino_zero/firmware.elf
-    (gdb) tar ext :3333
-    ...
-    (gdb) load
-    ...
-    (gdb) monitor reset init
-    ...
-    (gdb) continue
-
-Connecting
-----------
-
-Serial
-^^^^^^
-
-All boards are currently configured to work over USB rather than UART. To
-connect to it from OSX do something like this:
-
-    screen /dev/tty.usbmodem142422 115200
-
-You may not see a prompt immediately because it doesn't know you connected. To
-get one either hit enter to get `>>>` or do CTRL-B to get the full header.
-
-Mass storage
-^^^^^^^^^^^^
-
-All boards will also show up as a mass storage device. Make sure to eject it
-before resetting or disconnecting the board.

+ * Commands types:
+ * - broadcast commands (bc), no response
+ * - broadcast commands with response (bcr) (Note: No open drain on SD card)
+ * - addressed (point-to-point) commands (ac), no data transfer on DAT lines
+ * - addressed (point-to-point) data transfer commands (adtc), data transfer
+ * on DAT lines
+ *
+ * Specific MMC norms:
+ * CMD1, CMD2 & CMD3 are processed in the open-drain mode.
+ * The CMD line is driven with push-pull drivers.
+ *
+ * Specific SD norms:
+ * There is no open drain mode in SD memory card.
+ *
+ ***************************************
+ * Responses types:
+ *
+ * R1, R3, R4 & R5 use a 48 bits response protected by a 7bit CRC checksum
+ * - R1 receiv data not specified
+ * - R3 receiv OCR
+ * - R4, R5 RCA management (MMC only)
+ * - R6, R7 RCA management (SD only)
+ *
+ * R1b assert the BUSY signal and respond with R1.
+ * If the busy signal is asserted, it is done two clock cycles (Nsr time)
+ * after the end bit of the command. The DAT0 line is driven low.
+ * DAT1-DAT7 lines are driven by the card though their values are not relevant.
+ *
+ * R2 use a 136 bits response protected by a 7bit CRC checksum
+ * The content is CID or CSD
+ *
+ * Specific MMC norms:
+ * - R4 (Fast I/O) return RCA
+ * - R5 (interrupt request) return RCA null
+ *
+ * Specific SD norms:
+ * - R6 (Published RCA) return RCA
+ * - R7 (Card interface condition) return RCA null

+LiteX (FPGA)
+============
+
+`LiteX <https://github.com/enjoy-digital/litex>`_ is a Python-based System on a Chip (SoC) designer
+for open source supported Field Programmable Gate Array (FPGA) chips. This means that the CPU
+core(s) and peripherals are not defined by the physical chip. Instead, they are loaded as separate
+"gateware". Once this gateware is loaded, CircuitPython can be loaded on top of it to work as
+expected.
+
+Installation
+-------------
+
+You'll need ``dfu-util`` to install CircuitPython on the Fomu.
+
+Make sure the foboot bootloader is updated. Instructions are here: https://github.com/im-tomu/fomu-workshop/blob/master/docs/bootloader.rst
+
+Once you've updated the bootloader, you should know how to use ``dfu-util``. It's pretty easy!
+
+To install CircuitPython do:
+
+.. code-block:: shell
+
+  dfu-util -D adafruit-circuitpython-fomu-en_US-<version>.dfu
+
+It will install and then restart. CIRCUITPY should appear as it usually does and work the same.

+ *
+ * @param[out] p_dest Pointer to buffer to be filled in with an event, or NULL to retrieve the event length.

+ *                    The buffer should be interpreted as a @ref ble_evt_t struct.
+ * @param[in, out] p_len Pointer the length of the buffer, on return it is filled with the event length.
+ *
+ * @details This call allows the application to pull a BLE event from the BLE stack. The application is signaled that
+ * an event is available from the BLE stack by the triggering of the SD_EVT_IRQn interrupt.
+ * The application is free to choose whether to call this function from thread mode (main context) or directly from the
+ * Interrupt Service Routine that maps to SD_EVT_IRQn. In any case however, and because the BLE stack runs at a higher
+ * priority than the application, this function should be called in a loop (until @ref NRF_ERROR_NOT_FOUND is returned)
+ * every time SD_EVT_IRQn is raised to ensure that all available events are pulled from the BLE stack. Failure to do so
+ * could potentially leave events in the internal queue without the application being aware of this fact.
+ *
+ * Sizing the p_dest buffer is equally important, since the application needs to provide all the memory necessary for the event to
+ * be copied into application memory. If the buffer provided is not large enough to fit the entire contents of the event,
+ * @ref NRF_ERROR_DATA_SIZE will be returned and the application can then call again with a larger buffer size.
+ * The maximum possible event length is defined by @ref BLE_EVT_LEN_MAX. The application may also "peek" the event length
+ * by providing p_dest as a NULL pointer and inspecting the value of *p_len upon return:

+/**@brief Add a Vendor Specific base UUID.
+ *
+ * @details This call enables the application to add a Vendor Specific base UUID to the BLE stack's table, for later
+ * use with all other modules and APIs. This then allows the application to use the shorter, 24-bit @ref ble_uuid_t
+ * format when dealing with both 16-bit and 128-bit UUIDs without having to check for lengths and having split code
+ * paths. This is accomplished by extending the grouping mechanism that the Bluetooth SIG standard base UUID uses
+ * for all other 128-bit UUIDs. The type field in the @ref ble_uuid_t structure is an index (relative to
+ * @ref BLE_UUID_TYPE_VENDOR_BEGIN) to the table populated by multiple calls to this function, and the UUID field
+ * in the same structure contains the 2 bytes at indexes 12 and 13. The number of possible 128-bit UUIDs available to
+ * the application is therefore the number of Vendor Specific UUIDs added with the help of this function times 65536,
+ * although restricted to modifying bytes 12 and 13 for each of the entries in the supplied array.
+ *
+ * @note Bytes 12 and 13 of the provided UUID will not be used internally, since those are always replaced by
+ * the 16-bit uuid field in @ref ble_uuid_t.

+# Makerdiary Pitaya Go
+
+>Pitaya Go is a compact and versatile development platform for IoT solutions,
+combining the Nordic's high-end multiprotocol SoC nRF52840 and the Microchip's
+extreme low power Wi-Fi® network controller ATWINC1500B. It offers a complete
+solution for wireless connectivity with IEEE 802.11 b/g/n, Bluetooth 5, Thread
+and Zigbee, that is specifically designed for the IoT.
+Pitaya Go features a Battery Charger with power path management, 64Mbit ultra
+low power QSPI Flash memory, additional NFC-A Tag PCB Antenna, user
+programmable RGB LED and Buttons, reversible USB-C Connector and easily
+expandable Header Sockets. All these features above make this board an ideal
+choice for the next IoT project.
+
+from [Makerdiary](https://store.makerdiary.com/products/pitaya-go)
+
+
+## Installing CircuitPython submodules
+
+Before you can build, you will need to run the following commands once, which
+will install the submodules that are part of the CircuitPython ecosystem, and
+build the `mpy-cross` tool:
+
+```
+$ cd circuitpython
+$ git submodule update --init
+$ make -C mpy-cross
+```
+
+
+## Building
+```sh
+$ cd ports/nrf
+$ make BOARD=pitaya_go SD=s140 -V=1 -j4
+```
+
+# Flashing CircuitPython
+
+The Pitaya Go has a pre-programmed bootloader which can be used to program the
+Pitaya Go. Follow [the guide - How to Program Pitaya Go](https://wiki.makerdiary.com/pitaya-go/programming/)
+to flash the CircuitPython firmware.

+# Circuitpython on STM32 #
+
+This port brings the ST Microelectronics STM32 series of MCUs to Circuitpython. STM32 chips have a wide range of capability, from <$1 low power STM32F0s to dual-core STM32H7s running at 400+ MHz. Currently, only the F4, F7, and H7 families are supported, powered by the ARM Cortex M4 and M7 processors.
+
+Refer to the ST Microelectronics website for more information on features sorted by family and individual chip lines: [st.com/en/microcontrollers-microprocessors/stm32-high-performance-mcus.html](https://www.st.com/en/microcontrollers-microprocessors/stm32-high-performance-mcus.html)
+
+STM32 SoCs vary product-by-product in clock speed, peripheral capability, pin assignments, and their support within this port. Refer to **mpconfigport.mk** for a full list of enabled modules sorted by family.
+
+## How this port is organized: ##
+
+- **boards/** contains the configuration files for each development board and breakout available on the port, as well as system files and both shared and SoC-specific linker files. Board configuration includes a pin mapping of the board, oscillator information, board-specific build flags, and setup for OLED or TFT screens where applicable.
+- **common-hal/** contains the port-specific module implementations, used by shared-module and shared-bindings.
+- **packages/** contains package-specific pin bindings (LQFP100, BGA216, etc)
+- **peripherals/** contains peripheral setup files and peripheral mapping information, sorted by family and sub-variant. Most files in this directory can be generated with the python scripts in **tools/**.
+- **st-driver/** submodule for ST HAL and LL files generated via CubeMX. Shared with TinyUSB.
+- **supervisor/** contains port-specific implementations of internal flash, serial and USB, as well as the **port.c** file, which initializes the port at startup.
+- **tools/** python scripts for generating peripheral and pin mapping files in **peripherals/** and **board/**.
+
+At the root level, refer to **mpconfigboard.h** and **mpconfigport.mk** for port specific settings and a list of enabled modules.
+
+## Build instructions ##
+
+Ensure your clone of Circuitpython is ready to build by following the [guide on the Adafruit Website](https://learn.adafruit.com/building-circuitpython/introduction). This includes installing the toolchain, synchronizing submodules, and running `mpy-cross`.
+
+Once the one-time build tasks are complete, you can build at any time by navigating to the port directory:
+
+    $ cd ports/stm
+
+To build for a specific circuitpython board, run:
+
+    $ make BOARD=feather_stm32f405_express
+
+You may also build with certain flags available in the makefile, depending on your board and development goals. The following flags would enable debug information and correct flash locations for a pre-flashed UF2 bootloader:
+
+    $ make BOARD=feather_stm32f405_express DEBUG=1 UF2_BOOTLOADER=1
+
+## USB connection ##
+
+Connect your development board of choice to the host PC via the USB cable. Note that for most ST development boards such as the Nucleo and Discovery series, you must use a secondary OTG USB connector to access circuitpython, as the primary USB connector will be connected to a built-in ST-Link debugger rather than the chip itself.
+
+In many cases, this ST-Link USB connector will **still need to be connected to power** for the chip to turn on - refer to your specific product manual for details.
+
+## Flash the bootloader ##
+
+Most ST development boards come with a built-in STLink programming and debugging probe accessible via USB. This programmer may show up as an `MBED` drive on the host PC, enabling simple drag and drop programming with a .bin file, or they may require a tool like [OpenOCD](http://openocd.org/) or [StLink-org/stlink](https://github.com/stlink-org/stlink) to run flashing and debugging commands.
+
+Many hobbyist and 3rd party development boards also expose SWD pins. These can be used with a cheap [stlink](https://www.adafruit.com/product/2548) debugger or other common programmers.
+
+For non-ST products or users without a debugger, all STM32 boards in the high performance families (F4, F7 and H7) include a built-in DFU bootloader stored in ROM. This bootloader is accessed by ensuring the BOOT0 pin is held to a logic 1 and the BOOT1 pin is held to a logic 0 when the chip is reset ([ST Appnote AN2606](https://www.st.com/resource/en/application_note/cd00167594-stm32-microcontroller-system-memory-boot-mode-stmicroelectronics.pdf)). Most chips hold BOOT low by default, so this can usually be achieved by running a jumper wire from 3.3V power to the BOOT0 pin, if it is exposed, or by flipping the appropriate switch or button as the chip is reset. Once the chip is started in DFU mode, BOOT0 no longer needs to be held high and can be released. An example is available in the [Feather STM32F405 guide](https://learn.adafruit.com/adafruit-stm32f405-feather-express/dfu-bootloader-details).
+
+Windows users will need to install [stm32cubeprog](https://www.st.com/en/development-tools/stm32cubeprog.html), while Mac and Linux users will need to install `dfu-util` with `brew install dfu-util` or `sudo apt-get install dfu-util`. More details are available in the [Feather F405 guide](https://learn.adafruit.com/adafruit-stm32f405-feather-express/dfu-bootloader-details).
+
+## Flashing the circuitpython image with DFU-Util ##
+
+Ensure the board is in dfu mode by following the steps in the previous section. Then run:
+
+    $ make BOARD=feather_stm32F405_express flash
+
+Alternatively, you can navigate to the build directory and run the raw `dfu-util` command:
+
+`dfu-util -a 0 --dfuse-address 0x08000000 -D firmware.bin`
+
+## Accessing the board ##
+
+Connecting the board to the PC via the USB cable will allow code to be uploaded to the `CIRCUITPY` volume.
+
+Circuitpython exposes a CDC virtual serial connection for REPL access and debugging. Connecting to it from OSX will look something like this:
+
+    screen /dev/tty.usbmodem14111201 115200
+
+You may also use a program like [mu](https://codewith.mu/) to assist with REPL access.

+   * @brief  Update SystemCoreClock variable according to Clock Register Values.
+  *         The SystemCoreClock variable contains the core clock , it can
+  *         be used by the user application to setup the SysTick timer or configure
+  *         other parameters.
+  *
+  * @note   Each time the core clock changes, this function must be called
+  *         to update SystemCoreClock variable value. Otherwise, any configuration
+  *         based on this variable will be incorrect.
+  *
+  * @note   - The system frequency computed by this function is not the real
+  *           frequency in the chip. It is calculated based on the predefined
+  *           constant and the selected clock source:
+  *
+  *           - If SYSCLK source is CSI, SystemCoreClock will contain the CSI_VALUE(*)
+  *           - If SYSCLK source is HSI, SystemCoreClock will contain the HSI_VALUE(**)
+  *           - If SYSCLK source is HSE, SystemCoreClock will contain the HSE_VALUE(***)
+  *           - If SYSCLK source is PLL, SystemCoreClock will contain the CSI_VALUE(*),
+  *             HSI_VALUE(**) or HSE_VALUE(***) multiplied/divided by the PLL factors.
+  *
+  *         (*) CSI_VALUE is a constant defined in stm32h7xx_hal.h file (default value
+  *             4 MHz) but the real value may vary depending on the variations
+  *             in voltage and temperature.
+  *         (**) HSI_VALUE is a constant defined in stm32h7xx_hal.h file (default value
+  *             64 MHz) but the real value may vary depending on the variations
+  *             in voltage and temperature.
+  *
+  *         (***)HSE_VALUE is a constant defined in stm32h7xx_hal.h file (default value
+  *              25 MHz), user has to ensure that HSE_VALUE is same as the real
+  *              frequency of the crystal used. Otherwise, this function may
+  *              have wrong result.
+  *
+  *         - The result of this function could be not correct when using fractional
+  *           value for HSE crystal.
+  * @param  None
+  * @retval None

-  * @brief     STM32F405xx Devices vector table for GCC based toolchains. 
-  *            This module performs:
-  *                - Set the initial SP
-  *                - Set the initial PC == Reset_Handler,
-  *                - Set the vector table entries with the exceptions ISR address
-  *                - Branches to main in the C library (which eventually
-  *                  calls main()).
-  *            After Reset the Cortex-M4 processor is in Thread mode,
-  *            priority is Privileged, and the Stack is set to Main.

-  * @brief     STM32F405xx Devices vector table for GCC based toolchains. 
-  *            This module performs:
-  *                - Set the initial SP
-  *                - Set the initial PC == Reset_Handler,
-  *                - Set the vector table entries with the exceptions ISR address
-  *                - Branches to main in the C library (which eventually
-  *                  calls main()).
-  *            After Reset the Cortex-M4 processor is in Thread mode,
-  *            priority is Privileged, and the Stack is set to Main.

-  * @brief     STM32F411xExx Devices vector table for GCC based toolchains. 
-  *            This module performs:
-  *                - Set the initial SP
-  *                - Set the initial PC == Reset_Handler,
-  *                - Set the vector table entries with the exceptions ISR address
-  *                - Branches to main in the C library (which eventually
-  *                  calls main()).
-  *            After Reset the Cortex-M4 processor is in Thread mode,
-  *            priority is Privileged, and the Stack is set to Main.

-  * @brief     STM32F412Zx Devices vector table for GCC based toolchains. 
-  *            This module performs:
-  *                - Set the initial SP
-  *                - Set the initial PC == Reset_Handler,
-  *                - Set the vector table entries with the exceptions ISR address
-  *                - Branches to main in the C library (which eventually
-  *                  calls main()).
-  *            After Reset the Cortex-M4 processor is in Thread mode,
-  *            priority is Privileged, and the Stack is set to Main.

+//|         """Create a RGBMatrix object with the given attributes.  The height of
+//|         the display is determined by the number of rgb and address pins:
+//|         len(rgb_pins) // 3 * 2 ** len(address_pins).  With 6 RGB pins and 4
+//|         address lines, the display will be 32 pixels tall.  If the optional height
+//|         parameter is specified and is not 0, it is checked against the calculated
+//|         height.
+//|
+//|         Up to 30 RGB pins and 8 address pins are supported.
+//|
+//|         The RGB pins must be within a single "port" and performance and memory
+//|         usage are best when they are all within "close by" bits of the port.
+//|         The clock pin must also be on the same port as the RGB pins.  See the
+//|         documentation of the underlying protomatter C library for more
+//|         information.  Generally, Adafruit's interface boards are designed so
+//|         that these requirements are met when matched with the intended
+//|         microcontroller board.  For instance, the Feather M4 Express works
+//|         together with the RGB Matrix Feather.
+//|
+//|         The framebuffer is in "RGB565" format.
+//|
+//|         "RGB565" means that it is organized as a series of 16-bit numbers
+//|         where the highest 5 bits are interpreted as red, the next 6 as
+//|         green, and the final 5 as blue.  The object can be any buffer, but
+//|         `array.array` and `ulab.array` objects are most often useful.
+//|         To update the content, modify the framebuffer and call refresh.
+//|
+//|         If a framebuffer is not passed in, one is allocated and initialized
+//|         to all black.  In any case, the framebuffer can be retrieved
+//|         by passing the RGBMatrix object to memoryview().
+//|
+//|         If doublebuffer is False, some memory is saved, but the display may
+//|         flicker during updates.
+//|
+//|         A RGBMatrix is often used in conjunction with a
+//|         `framebufferio.FramebufferDisplay`."""

+//|
+//| The `watchdog` module provides support for a Watchdog Timer. This timer will reset the device
+//| if it hasn't been fed after a specified amount of time. This is useful to ensure the board
+//| has not crashed or locked up. Note that on some platforms the watchdog timer cannot be disabled
+//| once it has been enabled.
+//|
+//| The `WatchDogTimer` is used to restart the system when the application crashes and ends
+//| up into a non recoverable state. Once started it cannot be stopped or
+//| reconfigured in any way. After enabling, the application must "feed" the
+//| watchdog periodically to prevent it from expiring and resetting the system.
+//|
+//| Example usage::
+//|
+//|     from microcontroller import watchdog as w
+//|     from watchdog import WatchDogMode
+//|     w.timeout=2.5 # Set a timeout of 2.5 seconds
