This targets the 64-bit CPU Raspberry Pis. The BCM2711 on the Pi 4
and the BCM2837 on the Pi 3 and Zero 2W. There are 64-bit fixes
outside of the ports directory for it.
There are a couple other cleanups that were incidental:
* Use const mcu_pin_obj_t instead of omitting the const. The structs
themselves are const because they are in ROM.
* Use PTR <-> OBJ conversions in more places. They were found when
mp_obj_t was set to an integer type rather than pointer.
* Optimize submodule checkout because the Pi submodules are heavy
and unnecessary for the vast majority of builds.
Fixes#4314
F-strings, new machine.I2S class, ESP32-C3 support and LEGO_HUB_NO6 board
This release of MicroPython adds support for f-strings (PEP-498), with a
few limitations compared to normal Python. F-strings are essentially
syntactic sugar for "".format() and make formatting strings a lot more
convenient. Other improvements to the core runtime include pretty printing
OSError when it has two arguments (an errno code and a string), scheduling
of KeyboardInterrupt on the main thread, and support for a single argument
to the optimised form of StopIteration.
In the machine module a new I2S class has been added, with support for
esp32 and stm32 ports. This provides a consistent API for transmit and
receive of audio data in blocking, non-blocking and asyncio-based
operation. Also, the json module has support for the "separators" argument
in the dump and dumps functions, and framebuf now includes a way to blit
between frame buffers of different formats using a palette. A new,
portable machine.bitstream function is also added which can output a stream
of bits with configurable timing, and is used as the basis for driving
WS2812 LEDs in a common way across ports.
There has been some restructuring of the repository directory layout, with
all third-party code now in the lib/ directory. And a new top-level
directory shared/ has been added with first-party code that was previously
in lib/ moved there.
The docs have seen further improvement with enhancements and additions to
the rp2 parts, as well as a new quick reference for the zephyr port.
The terms master/slave have been replaced with controller/peripheral,
mainly relating to I2C and SPI usage. And u-module references have been
replaced with just the module name without the u-prefix to help clear up
the intended usage of modules in MicroPython.
For the esp8266 and esp32 ports, hidden networks are now included in WLAN
scan results. On the esp32 the RMT class is enhanced with idle_level and
write_pulses modes. There is initial support for ESP32-C3 chips with
GENERIC_C3 and GENERIC_C3_USB boards.
The javascript port has had its Makefile and garbage collector
implementation reworked so it compiles and runs with latest the Emscripten
using asyncify.
The mimxrt port sees the addition of hardware I2C and SPI support, as well
as some additional methods to the machine module. There is also support
for Hyperflash chips.
The nrf port now has full VFS storage support, enables source-line on
traceback, and has .mpy features consistent with other ports.
For the rp2 port there is now more configurability for boards, and more
boards added.
The stm32 port has a new LEGO_HUB_NO6 board definition with detailed
information how to get this LEGO Hub running stock MicroPython. There is
also now support to change the CPU frequency on STM32WB MCUs. And USBD_xxx
descriptor options have been renamed to MICROPY_HW_USB_xxx.

This switches stage2 to C and uses Jinja to change the C code based
on flash settings from https://github.com/adafruit/nvm.toml. It
produces the fastest settings for the given set of external flashes.
Flash size is no longer hard coded so switching flashes with similar
capabilities but different sizes should *just work*.
This PR also places "ITCM" code in RAM to save the XIP cache for
code execution. Further optimization is possible. A blink code.py
still requires a number of flash fetches every blink.
Fixes#4041
The RP2040 is new microcontroller from Raspberry Pi that features
two Cortex M0s and eight PIO state machines that are good for
crunching lots of data. It has 264k RAM and a built in UF2
bootloader too.
Datasheet: https://pico.raspberrypi.org/files/rp2040_datasheet.pdf
This library is a small and easy-to-use cryptographic library which is well
suited to embedded systems.

This re-points the submodule to my personal fork of esp-idf.
Users may need to `git submodule sync` in their existing trees when
this change occurs.
Adds just the following commit in esp-idf:
> esp_crt_bundle: Allow verify_callback to correct BADCERT_BAD_MD
This is an extremely minimal port to the NXP i.MX RT, in the style of the
SAMD port It's largely based on the TinyUSB mimxrt implementation, using
the NXP SDK. It currently supports the Teensy 4.0 board with a REPL over
the USB-VCP interface.
This commit also adds the NXP SDK submodule (also from TinyUSB) to
lib/nxp_driver.
Note: if you already have the tinyusb submodule initialized recursively you
will need to run the following as the tinyusb sub-submodules have been
rearranged (upstream):
git submodule deinit lib/tinyusb
rm -rf .git/modules/lib/tinyusb
git submodule update --init lib/tinyusb
Introduces a way to place CircuitPython code and data into
tightly coupled memory (TCM) which is accessible by the CPU in a
single cycle. It also frees up room in the corresponding cache for
intermittent data. Loading from external flash is slow!
The data cache is also now enabled.
Adds support for the iMX RT 1021 chip. Adds three new boards:
* iMX RT 1020 EVK
* iMX RT 1060 EVK
* Teensy 4.0
Related to #2492, #2472 and #2477. Fixes#2475.
This started while adding USB MIDI support (and descriptor support is
in this change.) When seeing that I'd have to implement the MIDI class
logic twice, once for atmel-samd and once for nrf, I decided to refactor
the USB stack so its shared across ports. This has led to a number of
changes that remove items from the ports folder and move them into
supervisor.
Furthermore, we had external SPI flash support for nrf pending so I
factored out the connection between the usb stack and the flash API as
well. This PR also includes the QSPI support for nRF.
This saves code space in builds which use link-time optimization.
The optimization drops the untranslated strings and replaces them
with a compressed_string_t struct. It can then be decompressed to
a c string.
Builds without LTO work as well but include both untranslated
strings and compressed strings.
This work could be expanded to include QSTRs and loaded strings if
a compress method is added to C. Its tracked in #531.
Summarized this squashed PR replaces the hal/ folder in the port. This has been replaced the official
HAL layer from Nordic Semiconductor; https://github.com/NordicSemiconductor/nrfx.
A Git submodule has been added under lib/nrfx, for the nrfx dependency.
The drivers / modules has been updated to use this new HAL layer; nrfx at v1.0.0.
Also, header files and system files for nrf51/nrf52x chip variants has been deleted from the device/ folder, only keeping back the startup files written in C. All other files are now fetched from nrfx.
3 new header files in the ports/nrf/ folder has been added to configure nrfx (nrfx_config.h), logging (nrfx_log.h) and glue nrfx together with the drivers and modules from micropython (nrfx_glue.h).
The PR has been a joint effort from @aykevl (Ayke van Laethem) and @glennrub.
For reference, the commit log will be kept to get an overview of the changes done:
* ports/nrf: Initial commit for moving hal to Nordic Semiconductor BSD-3 licensed nrfx-hal.
* ports/nrf: Adding nrfx, Nordic Semiconductor BSD-3 hal layer, as git submodule checked out at lib/nrfx.
* ports/nrf/modules/machine/uart: Fixing bug which set hwfc to parity excluded, always resulting in no flow control, hence corrupted output. Also adding an extra loop on uart_tx_char to prevent any tx when any ongoing tx is in progress.
* ports/nrf/i2c: Moving I2C over to nrfx driver.
* ports/nrf/modules/machine/i2c: Alignment. Renaming print function param 'o' to 'self_in'
* ports/nrf/spi: Updating SPI machine module to use nrfx drivers.
* ports/nrf: Renaming modules/machine/rtc.c/.h to rtcounter.c/.h to not confuse the peripheral with Real-Time Clock:
* ports/nrf: Updating various files after renaming machine module RTC to RTCounter.
* ports/nrf: Renaming RTC to RTCounter in modmachine globals dict table. Also updating object type name to reflect new module name.
* ports/nrf: Fixing leftovers after renaming rtc to rtcounter.
* ports/nrf: Early untested adoption of nrfx_rtc in RTCounter. Untested.
* nrf/modules/machine/i2c: Improve keyword argument handling
* ports/nrf/modules/temp: Updating Temp machine module to use nrfx defined hal nrf_temp.h. Moving logic of BLE stack awareness to machine module.
* ports/nrf/boards/pca10040: Enable machine Temp module.
* nrf/modules/machine/rtcounter: Remove magic constants.
* ports/nrf: Adding base support for nrfx module logging. Adding option to disable logging of UART as it might log its own setup over UART while the peripheral is not yet set up. Logging of UART could make sense if other transport of log is used.
* ports/nrf: updating nrfx_log.h with more correct parenthisis on macro grouping.
* ports/nrf: Updating nrfx logging with configuration to disable logging of UART module. The pattern can be used to turn off other modules as well. However, for now UART is the only module locking itself by logging before the peripheral is configured. Logging is turned off by default, can be enabled in nrfx_config.h by setting NRFX_LOG_ENABLED=1.
* ports/nrf/modules/random: Updating modrandom to use nrfx hal for rng. Not using nrfx-driver for this peripheral as its blocking mode would do the trick on RNG. Moving softdevice aware code from legacy hal to modrandom.c.
* nrf: Enable Peripheral Resource Sharing.
This enables TWI and SPI to be enabled at the same time.
* nrf/Makefile: Define MCU sub variant (e.g. NRF51822/NRF51422)
* nrf: Port TIMER peripheral to nrfx HAL.
* nrf/modules/machine/uart: Optimize UART module
For a nRF51, this results in a size reduction of:
.text: -68 bytes
.data: -56 bytes
* nrf/modules/machine/uart: Don't use magic index numbers.
* nrf/modules/machine/uart: Fix off-by-one error.
For nrf51:
.text: -40 bytes
* nrf/modules/machine/rtcounter: Update for nrfx HAL.
* nrf/modules/machine/i2c: Reduce RAM consumption.
Reductions for the nrf51:
flash: -108 bytes
RAM: -72 bytes
* nrf/mpconfigport: Avoid unnecessary root pointers.
This saves 92 bytes of RAM.
* nrf: Support SoftDevice with nrfx HAL.
* nrf: Add NVMC peripheral (microbitfs) support.
There is no support yet for a SoftDevice.
It also fixes a potentially serious bug in start_index generation.
* nrf/modules/machine/spi: Optimize SPI peripheral.
nrf51:
text: -340 bytes
data: -72 bytes
nrf52:
text: -352 bytes
data: -108 bytes
* nrf/modules/random: Forgot to commit header file.
* nrf: Make nrfx_config.h universal for all boards.
* nrf: Use SoftDevice API for flash access when built for SD
* nrf/drivers/bluetooth: Remove legacy HAL driver includes.
These were not used anymore so can be removed.
* ports/nrf/microbit: Port microbit targets to nrfx HAL
Initial port of microbit modules to use nrfx HAL layer.
Tested display/image and modmusic on micro:bit to verify that
softpwm and ticker for nrf51 is working as expected.
Changing IRQ priority on timer to priority 2, as 1 might collide if
used side by side of SD110 BLE stack.
The patch reserves Timer1 peripheral compile time. This is not ideal
and should be resolved in seperate task.
* nrf/boards/microbit: Remove custom nrfx_config.h from microbit target, adding disablement of timer1 if softpwm is enabled.
* nrf/adc: Update ADC module to use nrfx
* nrf/modules/machine/pwm: Updating machine PWM module to use nrfx HAL driver.
examples/nrf52_pwm.py and examples/nrf52_servo.py tested on pca10040.
* nrf: Removing hal folder and boards nrf5x_hal_conf.h headers.
* nrf/nrfx_glue: Adding direct NVIC access for S110 BLE stack
If SoftDevice s110 has not yet been initialized, the IRQ will not be forwarded to
the application using the sd_nvic* function calls. Hence, direct access to cmsi
nvic functions are used instead if SoftDevice is not enabled.
* nrf/drivers/ticker: Setting IRQ priority 3 on Timer1
SoftDevice fails to initilize if Timer1 has been configured to priority
level 2 before enabling the SD. The timer is set to priority 1, higher than BLE
stack in order to provide better quality of music rendering when used with the
music module. This might be too high, time will show.
* nrf/examples: Updating ubluepy_temp after moving RTCounter to nrfx.
* nrf: delete duplicate files from device folder which can be located in nrfx/mdk.
* nrf/Makefile: Fetch system files from nrfx.
Testing on each device sub-variant to figure out which system file to
use. Reason for this is that nrf52.c is actually defining nrf52832.
Removing NRF_DEFINES parameter setting the device in use into the
same sub-variant test, as NRF52 is unique to nrf52832 when using nrfx.
Without this exclusion of -DNRF52 in compilation for nrf52840, the
device will be interpreted as a nrf52, hence nrf52832.
Also, changing name on variable SRC_NRF_HAL to SRC_NRFX_HAL to
explicitly tell the origin of the file.
* nrf: Updating device #ifdefs to be more open to non-nrf51 targets.
* nrf/modules/machine/uart: Removing second instance of UART for nrf52840 as it only has one non-DMA variant.
* nrf/device: Removing system files as these are now used from nrfx/mdk
* nrf: Moving startup files in device one level up as there is no need for deep hierarchy.
* nrf: Use NRF52_SERIES defined in nrfx/mdk/nrf.h as define value when testing for both nrf52(832) and nrf52840 variants.
* nrf/modules/machine/uart: Enable UART RX by default
Enable rx by default after intiialization of the peripheral.
Else, the nrfx driver will re-enable rx for each byte read
on uart REPL, clearing the EVENT_RXDRDY before second byte,
which again will make second byte get lost and read will get stuck.
This happens if the bytes are transmitted nrf(51) while still
processing the previous byte. Not seen on nrf52, but should
also become an issue at higher speeds.
This patch sets rx to always be enabled. Hence, not clearing the event
between read bytes, and it will be able to detect next byte recieved
upon finishing the first.
* nrf/modules/machine/timer: Fixing defines excluding Timer1 if ticker/softpwm is used.
* nrf: Switching import form mpconfigboard.h to mpconfigport.h in nrfx_config.h as mpconfigboard.h might define default values for defines not set by board specific header.
* nrf/modules/machine/i2c: nrfx integration fixes
Increasing speed to 400K.
Returning Address NACK's as MP error code; MP_ENODEV.
Returning MP_ETIMEOUT on all other error codes from TWI nrfx driver
except the ANACK.
Enabling and disabling the TWI peripheral before and after each transaction.
* nrf/examples: Updating ssd1306_mod.py to split framebuffer transfer into multiple chunks
* nrf/modules/machine/i2c: Return MP_EIO error if Data NACK occurs.
* nrf: Addressing review comments.
* nrf: Updating git submodule and users to nrfx v1.0.0.
* nrf/modules/machine/adc: Update adc module to follow v1.0.0 nrfx API.
* nrf/modules/machine/spi: Implement init and deinit functions
Extending SPI objects with a config member such that
configuration can be kept between new() and init().
Moving initialization done in new() to common init
function shared between the module functions.
If SPI is already configured, the SPI peripheral will
be uninitialized before initalized again.
Adding logic to handle initialization of polarity and
phase. As well, updating default speed to 1M from 500K.
* nrf/modules/machine: Removing unused nrfx includes in machine module header files
Textualy, the files in lib/uzlib/src were identical to the ones committed
in extmod/uzlib so there should be no behavioral change possible as a
result of this commit.
This saves a lot of RAM. Fixes#287.
Also fixed compilation of frozen_mpy.c to use supplied make rule rather than
builtin rule (supplied rule suppresses printing out the gcc command line).
Reworked frozen module support: clean up makefiles and handle multiple directories.
Modules to freeze are included as git submodules.
Add neopixel to circuitplayground express build.
Fixes#56
