Damien George b73adcc3d9 stm32: Rename i2c.c to pyb_i2c.c.
i2c.c implements the legacy pyb.I2C class so rename the file to make this
explicit, and also to make room for an improved I2C driver.

Damien George 8b91260169 stm32/dac: Support MCUs that don't have TIM4/5 and use new HAL macro. 2018-04-24 12:07:59 +10:00
Damien George 8a949ba599 stm32: Introduce MICROPY_PY_STM config to include or not the stm module.
By default the stm module is included in the build, but a board can now
define MICROPY_PY_STM to 0 to not include this module.  This reduces the
firmware by about 7k.

Damien George 3d5d76fb73 stm32/main: Allow a board to configure the label of the flash FS.
To change the default label a board should define:

    #define MICROPY_HW_FLASH_FS_LABEL "label"
2018-04-11 16:52:22 +10:00
Damien George cf9fc7346d stm32: Allow a board to configure the HSE in bypass mode.
To use HSE bypass mode the board should define:

    #define MICROPY_HW_CLK_USE_BYPASS (1)

If this is not defined, or is defined to 0, then HSE oscillator mode is
used.

Damien George 68b70fac5c stm32/stm32_it: Add IRQ handler for I2C4. 2018-04-11 16:37:45 +10:00
Damien George a7ebac2eae stm32/can: Allow CAN pins to be configured per board.
This patch allows a given board to configure which pins are used for the
CAN peripherals, in a similar way to all the other bus peripherals (I2C,
UART, SPI).  To enable CAN on a board the mpconfigboard.h file should
define (for example):

    #define MICROPY_HW_CAN1_TX (pin_B9)
    #define MICROPY_HW_CAN1_RX (pin_B8)
    #define MICROPY_HW_CAN2_TX (pin_B13)
    #define MICROPY_HW_CAN2_RX (pin_B12)

And the board config file should no longer define MICROPY_HW_ENABLE_CAN.

Damien George 0041396f05 stm32/pin: In pin AF object, remove union of periph ptr types.
The individual union members (like SPI, I2C) are never used, only the
generic "reg" entry is.  And the union names can clash with macro
definitions in the HAL so better to remove them.

Damien George f1073e747d stm32/adc: Factor common ADC init code into adcx_init_periph().
The only configuration that changes with this patch is that on L4 MCUs the
clock prescaler changed from ADC_CLOCK_ASYNC_DIV2 to ADC_CLOCK_ASYNC_DIV1
for the ADCAll object.  This should be ok.
2018-04-11 14:46:13 +10:00
Damien George 1d6c155d6a stm32/adc: Fix config of EOC selection and Ext-Trig for ADC periph.
A value of DISABLE for EOCSelection is invalid.  This would have been
interpreted instead as ADC_EOC_SEQ_CONV, but really it should be
ADC_EOC_SINGLE_CONV for the uses in this code.  So this has been fixed.

ExternalTrigConv should be ADC_SOFTWARE_START because all ADC
conversions are started by software.  This is now fixed.

Damien George b30e0d2f26 stm32/dac: Add buffering argument to constructor and init() method.
This can be used to select the output buffer behaviour of the DAC.  The
default values are chosen to retain backwards compatibility with existing
behaviour.

Thanks to @peterhinch for the initial idea to add this feature.

Damien George cf31d384f1 py/stream: Switch stream close operation from method to ioctl.
This patch moves the implementation of stream closure from a dedicated
method to the ioctl of the stream protocol, for each type that implements
closing.  The benefits of this are:

1. Rounds out the stream ioctl function, which already includes flush,
   seek and poll (among other things).

2. Makes calling mp_stream_close() on an object slightly more efficient
   because it now no longer needs to lookup the close method and call it,
   rather it just delegates straight to the ioctl function (if it exists).

3. Reduces code size and allows future types that implement the stream
   protocol to be smaller because they don't need a dedicated close method.

Code size reduction is around 200 bytes smaller for x86 archs and around
30 bytes smaller for the bare-metal archs.

Damien George bc3a5f1917 stm32/mphalport: Use MCU regs to detect if cycle counter is started.
Instead of using a dedicated variable in RAM it's simpler to use the
relevant bits in the DWT register.

Damien George b833f170c3 stm32/main: Only update reset_mode if board doesn't use a bootloader.
If the board is configured to use a bootloader then that bootloader will
pass through the reset_mode.
2018-03-29 16:16:58 +11:00
Damien George 7856a416bd stm32/main: Rename main to stm32_main and pass through first argument.
The main() function has a predefined type in C which is not so useful for
embedded contexts.  This patch renames main() to stm32_main() so we can
define our own type signature for this function.  The type signature is
defined to have a single argument which is the "reset_mode" and is passed
through as r0 from Reset_Handler.  This allows, for example, a bootloader
to pass through information into the main application.
2018-03-29 16:15:57 +11:00
Damien George d9e69681f5 stm32: Add custom, optimised Reset_Handler code.
The Reset_Handler needs to copy the data section and zero the BSS, and
these operations should be as optimised as possible to reduce start up
time.  The versions provided in this patch are about 2x faster (on a Cortex
M4) than the previous implementations.
2018-03-29 15:29:23 +11:00
Damien George 7e28212352 stm32/boards/STM32L476DISC: Update to not take the address of pin objs. 2018-03-28 16:29:55 +11:00
Damien George 2dca693c24 stm32: Change pin_X and pyb_pin_X identifiers to be pointers to objects.
Rather than pin objects themselves.  The actual object is now pin_X_obj and
defines are provided so that pin_X is &pin_X_obj.  This makes it so that
code that uses pin objects doesn't need to know if they are literals or
objects (that need pointers taken) or something else.  They are just
entities that can be passed to the map_hal_pin_xxx functions.  This mirrors
how the core handles constant objects (eg mp_const_none which is
&mp_const_none_obj) and allows for the possibility of different
implementations of the pin layer.

For example, prior to this patch there was the following:

    extern const pin_obj_t pin_A0;
    #define pyb_pin_X1 pin_A0
    ...
    mp_hal_pin_high(&pin_A0);

and now there is:

    extern const pin_obj_t pin_A0_obj;
    #define pin_A0 (&pin_A0_obj)
    #define pyb_pin_X1 pin_A0
    ...
    mp_hal_pin_high(pin_A0);

This patch should have minimal effect on board configuration files.  The
only change that may be needed is if a board has .c files that configure
pins.

iabdalkader 9b9896b44d stm32/dma: Remove H7 SDMMC DMA descriptors.
The H7 SD peripheral has direct connection to MDMA instead.

Damien George 1efe6a0316 stm32/boards/NUCLEO_H743ZI: Update to build with new linker management. 2018-03-28 13:20:48 +11:00
Damien George b121c9515d stm32/boards/stm32h743.ld: Remove include of common.ld.
The relevant common.ld file should now be included explicitly by a
particular board.
2018-03-28 13:20:07 +11:00
Damien George 4d409b8e32 stm32/boards/stm32f767.ld: Add definition of FLASH_APP.
This allows F767 MCUs to support a bootloader in the first sector.
2018-03-27 21:35:03 +11:00
Damien George 04de9e33bc stm32/system_stm32: Set VTOR pointer from TEXT0_ADDR. 2018-03-27 21:32:39 +11:00
Damien George dcf4eb8134 stm32/boards: Add common_bl.ld for boards that need a bootloader. 2018-03-27 21:30:45 +11:00
Damien George ddb3b84c70 stm32/boards: Add common_basic.ld for a board to have a single section. 2018-03-27 21:29:45 +11:00
Damien George ed75b2655f stm32/Makefile: Allow a board to config either 1 or 2 firmware sections.
This patch forces a board to explicitly define TEXT1_ADDR in order to
split the firmware into two separate pieces.  Otherwise the default is now
to produce only a single continuous firmware image with all ISR, text and
data together.
2018-03-27 21:24:15 +11:00
Damien George 95b2cb008e stm32/Makefile: Rename FLASH_ADDR/TEXT_ADDR to TEXT0_ADDR/TEXT1_ADDR.
To make it clearer that these addresses are both for firmware text and that
they have a prescribed ordering.
2018-03-27 21:20:04 +11:00
Damien George 7aec06ca9a stm32/boards: Allow boards to have finer control over the linker script.
This patch allows a particular board to independently specify the linker
scripts for 1) the MCU memory layout; 2) how the different firmware
sections are arranged in memory.  Right now all boards follow the same
layout with two separate firmware section, one for the ISR and one for the
text and data.  This leaves room for storage (filesystem data) to live
between the firmware sections.

The idea with this patch is to accommodate boards that don't have internal
flash storage and only need to have one continuous firmware section.  Thus
the common.ld script is renamed to common_ifs.ld to make explicit that it
is used for cases where the board has internal flash storage.

Damien George a6009a9e35 stm32/*bdev.c: Eliminate dependency on sys_tick_has_passed.
Explicitly writing out the implementation of sys_tick_has_passed makes
these bdev files independent of systick.c and more reusable as a general
component.  It also reduces the code size slightly.

The irq.h header is added to spibdev.c because it uses declarations in that
file (irq.h is usually included implicitly via mphalport.h but not always).
2018-03-27 20:38:57 +11:00
Damien George 6f1e857624 stm32/qspi: Don't take the address of pin configuration identifiers.
Taking the address assumes that the pin is an object (eg a struct), but it
could be a literal (eg an int).  Not taking the address makes this driver
more general for other uses.
2018-03-27 20:34:55 +11:00
Damien George 6b51eb22c8 stm32: Consolidate include of genhdr/pins.h to single location in pin.h.
genhdr/pins.h is an internal header file that defines all of the pin
objects and it's cleaner to have pin.h include it (where the struct's for
these objects are defined) rather than an explicit include by every user.

Damien George b63cc1e9ef stm32/Makefile: Re-enable strict aliasing optimisation for ST HAL files.
The HAL requires strict aliasing optimisation to be turned on to function
correctly (at least for the SD card driver on F4 MCUs).  This optimisation
was recently disabled with the addition of H7 support due to the H7 HAL
having errors with the strict aliasing optimisation enabled.  But this is
now fixed in the latest stm32lib and so the optimisation can now be
re-enabled.

Thanks to @chuckbook for finding that there was a problem with the SD card
on F4 MCUs with the strict aliasing optimisation disabled.

iabdalkader 1e0a67f290 stm32/boards/NUCLEO_H743ZI: Enable hardware I2C support. 2018-03-20 23:25:43 +11:00
iabdalkader 24a9facd89 stm32/i2c: Add H7 I2C timing configurations.
Found the timing for full (400 KHz) and FM+ (1MHz) in the HAL examples, and
used CubeMX to calculate the standard value (100KHz).
2018-03-20 23:25:01 +11:00
iabdalkader 2ebc538d63 stm32/dma: Enable H7 DMA descriptors. 2018-03-20 23:24:45 +11:00
Damien George 0abbafd424 stm32/can: Add "list" param to CAN.recv() to receive data inplace.
This API matches (as close as possible) how other pyb classes allow inplace
operations, such as pyb.SPI.recv(buf).
2018-03-19 15:12:24 +11:00
Damien George e37b8ba5a5 stm32: Use STM32xx macros instead of MCU_SERIES_xx to select MCU type.
The CMSIS files for the STM32 range provide macros to distinguish between
the different MCU series: STM32F4, STM32F7, STM32H7, STM32L4, etc.  Prefer
to use these instead of custom ones.
2018-03-17 10:42:50 +11:00
Damien George 06aa13c350 stm32/can: Use explicit byte extraction instead of casting to word ptr.
Casting the Data array to a uint32_t* leads to strict aliasing errors on
older gcc compilers.
2018-03-16 23:52:13 +11:00
Damien George a25e6c6b65 stm32/can: Add CAN.info() method to retrieve error and tx/rx buf info. 2018-03-16 18:28:35 +11:00
Damien George d7e67fb1b4 stm32/can: Add CAN.state() method to get the state of the controller.
This is useful for monitoring errors on the bus and knowing when a restart
is needed.
2018-03-16 17:10:41 +11:00
Damien George 1272c3c65d stm32/can: Add CAN.restart() method so controller can leave bus-off. 2018-03-15 17:29:30 +11:00

Damien George 1608c4f5be stm32/can: Use enums to index keyword arguments, for clarity. 2018-03-15 17:15:41 +11:00
Damien George 2036196d71 stm32/can: Improve can.recv() so it checks for events, eg ctrl-C.
This patch provides a custom (and simple) function to receive data on the
CAN bus, instead of the HAL function.  This custom version calls
mp_handle_pending() while waiting for messages, which, among other things,
allows to interrupt the recv() method via KeyboardInterrupt.

Damien George 1345093401 stm32/qspi: Do an explicit read instead of using memory-mapped mode.
Using an explicit read eliminates the need to invalidate the D-cache after
enabling the memory mapping mode, which takes additional time.

Damien George 0d5bccad11 stm32/storage: Provide support for a second block device. 2018-03-10 01:03:27 +11:00
Damien George bb3359f357 stm32/boards/STM32L476DISC: Provide SPI-flash bdev config.
This board shows how to configure external SPI flash as the main storage
medium.  It uses software SPI.
2018-03-10 00:59:43 +11:00
Damien George 626d6c9756 stm32/storage: Introduce MICROPY_HW_ENABLE_INTERNAL_FLASH_STORAGE cfg.
This config variable controls whether to support storage on the internal
flash of the MCU.  It is enabled by default and should be explicitly
disabled by boards that don't want internal flash storage.
2018-03-10 00:59:43 +11:00
Damien George d1c4bd69df stm32/storage: Remove all SPI-flash bdev cfg, to be provided per board.
If a board wants to use SPI flash for storage then it must now provide the
configuration itself, using the MICROPY_HW_BDEV_xxx macros.
2018-03-10 00:59:43 +11:00
Damien George 1803e8ef22 stm32/storage: Make spi_bdev interface take a data pointer as first arg.
This allows a board to have multiple instances of the SPI block device.
2018-03-10 00:59:43 +11:00
Damien George 1e4caf0b1e stm32/storage: Merge all misc block-dev funcs into a single ioctl func.
It makes it cleaner, and simpler to support multiple different block
devices.  It also allows to easily extend a given block device with new
ioctl operations.
2018-03-10 00:59:43 +11:00
Damien George a739b35a96 drivers/memory/spiflash: Change to use low-level SPI object not uPy one.
This patch alters the SPI-flash memory driver so that it uses the new
low-level C SPI protocol (from drivers/bus/spi.h) instead of the uPy SPI
protocol (from extmod/machine_spi.h).  This allows the SPI-flash driver to
be used independently from the uPy runtime.
2018-03-10 00:59:43 +11:00
Damien George 58ebeca6a9 drivers/bus: Pull out software SPI implementation to dedicated driver.
This patch takes the software SPI implementation from extmod/machine_spi.c
and moves it to a dedicated file in drivers/bus/softspi.c.  This allows the
SPI driver to be used independently of the uPy runtime, making it a more
general component.

Damien George adda38cf76 stm32/qspi: Add hardware QSPI driver, with memory-map capability.
It supports the abstract QSPI protocol defined in drivers/bus/qspi.h.
2018-03-03 00:17:08 +11:00
Damien George 8bd0a51ca9 stm32/spibdev: Convert to use multiple block read/write interface.
The spiflash driver now supports read/write of multiple blocks at a time.
2018-03-03 00:13:15 +11:00
Damien George 861080aa3d stm32/storage: Add option for bdev to supply readblock/writeblocks.
If the underlying block device supports it, it's more efficient to
read/write multiple blocks at once.
2018-03-02 23:57:53 +11:00
Damien George 0210383da5 stm32/spibdev: Add option to configure SPI block dev to use QSPI flash.
To use QSPI (in software QSPI mode) the configuration needed is:

    #define MICROPY_HW_SPIFLASH_SIZE_BITS (n * 1024 * 1024)
    #define MICROPY_HW_SPIFLASH_CS      (pin_x1)

Damien George 989fc16162 stm32: Move MCU-specific cfg from mphalport.h to mpconfigboard_common.h.
It's cleaner to have all the MCU-specific configuration in one location,
not least to help with adding support for a new MCU series.
2018-02-23 16:54:07 +11:00
Damien George ea05b400df stm32/flash: Use FLASH_TYPEPROGRAM_WORD to support newer HALs. 2018-02-23 16:30:47 +11:00
Damien George e6220618ce stm32: Use "GEN" for describing files generated in the build.
Instead of "Create", to match the build output from the py/ core.
2018-02-23 16:27:30 +11:00
Damien George 60b0982bb2 stm32: Add board config option to enable/disable the ADC.
The new option is MICROPY_HW_ENABLE_ADC and is enabled by default.
2018-02-22 14:22:45 +11:00
Damien George 82828340a0 ports: Enable ucollections.deque on relevant ports.
These ports are all capable of running uasyncio.
2018-02-21 22:55:13 +11:00
Damien George d966a33486 stm32: Change header include guards from STMHAL to STM32 to match dir. 2018-02-15 15:47:04 +11:00
Damien George fa13e0d35b stm32: Factor out flash and SPI block-device code to separate files.
Prior to this patch, storage.c was a combination of code that handled
either internal flash or external SPI flash and exposed one of them as a
block device for the local storage.  It was also exposed to the USB MSC.

This patch splits out the flash and SPI code to separate files, which each
provide a general block-device interface (at the C level).  Then storage.c
just picks one of them to use as the local storage medium.  The aim of this
factoring is to allow to add new block devices in the future and allow for
easier configurability.
2018-02-13 22:21:46 +11:00
Damien George 34911f1a57 stm32/boards: Update all boards to work with new USB configuration. 2018-02-13 18:57:01 +11:00
Damien George 5c320bd0b0 stm32: Introduce MICROPY_HW_ENABLE_USB and clean up USB config.
This patch allows to completely compile-out support for USB, and no-USB is
now the default.  If a board wants to enable USB it should define:

    #define MICROPY_HW_ENABLE_USB (1)

And then one or more of the following to select the USB PHY:

    #define MICROPY_HW_USB_FS (1)
    #define MICROPY_HW_USB_HS (1)
    #define MICROPY_HW_USB_HS_IN_FS (1)
2018-02-13 18:51:08 +11:00
Damien George 8aad22fdca stm32/timer: Support MCUs that don't have TIM4 and/or TIM5. 2018-02-13 15:53:39 +11:00
Damien George 6e91ab5806 stm32/spi: Further updates to use newer versions of HAL names. 2018-02-13 15:53:08 +11:00
Damien George 3eb0694b97 stm32: Update HAL macro and constant names to use newer versions.
Newer versions of the HAL use names which are cleaner and more
self-consistent amongst the HAL itself.  This patch switches to use those
names in most places so it is easier to update the HAL in the future.
2018-02-13 15:37:35 +11:00
Damien George 8e1cb58a23 stm32/usbdev: Fix USBD setup request handler to use correct recipient.
Prior to this patch the USBD driver did not handle the recipient correctly
for setup requests.  It was not interpreting the req->wIndex field in the
right way: in some cases this field indicates the endpoint number but the
code was assuming it always indicated the interface number.

This patch fixes this.  The only noticeable change is to the MSC
interface, which should now correctly respond to the USB_REQ_CLEAR_FEATURE
request and hence unmount properly from the host when requested.
2018-02-12 17:22:59 +11:00
Damien George 02f88cb2df stm32/boards: Remove all config options that are set to defaults.
mpconfigboard_common.h now sets the defaults so there is no longer a need
to explicitly list all configuration options in a board's mpconfigboard.h
file.
2018-02-09 18:40:40 +11:00
Damien George 2d5bab46be stm32: Add mpconfigboard_common.h with common/default board settings.
This file mirrors py/mpconfig.h but for board-level config options.  It
provides a default configuration, to be overridden by a specific
mpconfigboard.h file, as well as setting up certain macros to automatically
configure a board.
2018-02-09 18:40:13 +11:00
Damien George cc92c0572e stm32/main: Remove need for first_soft_reset variable. 2018-02-05 16:13:05 +11:00
Damien George 4607be3768 stm32/main: Reorder some init calls to put them before soft-reset loop.
The calls to rtc_init_start(), sdcard_init() and storage_init() are all
guarded by a check for first_soft_reset, so it's simpler to just put them
all before the soft-reset loop, without the check.

The call to machine_init() can also go before the soft-reset loop because
it is only needed to check the reset cause which can happen once at the
first boot.  To allow this to work, the reset cause must be set to SOFT
upon a soft-reset, which is the role of the new function machine_deinit().
2018-02-05 15:52:36 +11:00
Damien George 12464f1bd2 stm32/rtc: Add compile-time option to set RTC source as LSE bypass.
To use the LSE bypass feature (where an external source provides the RTC
clock) a board must set the config variable MICROPY_HW_RTC_USE_BYPASS.
2018-02-05 15:22:15 +11:00
Damien George 011d1555cb stm32/rtc: Fix RTC init to use LSI if LSI is already selected on boot.
Upon boot the RTC early-init function should detect if LSE or LSI is
already selected/running and, if so, use it.  When the LSI has previously
(in the previous reset cycle) been selected as the clock source the only
way to reliably tell is if the RTCSEL bits of the RCC_BDCR are set to the
correct LSI value.  In particular the RCC_CSR bits for LSI control do not
indicate if the LSI is ready even if it is selected.

This patch removes the check on the RCC_CSR bits for the LSI being on and
ready and only uses the check on the RCC_BDCR to see if the LSI should be
used straightaway.  This was tested on a PYBLITEv1.0 and with the patch the
LSI persists correctly as the RTC source as long as the backup domain
remains powered.
2018-02-05 15:12:22 +11:00
Damien George 5a62f0faa6 stm32/rtc: Fix rtc_info flags when LSE fails and falls back to LSI.
Previously, if LSE is selected but fails and the RTC falls back to LSI,
then the rtc_info flags would incorrectly state that LSE is used.  This
patch fixes that by setting the bit in rtc_info only after the clock is
ready.
2018-02-05 14:40:06 +11:00
Damien George 20f5de9b39 stm32/spi: Accept machine.SPI object in spi_from_mp_obj() function.
Also, change ValueError to TypeError if the argument to this function is
not of an SPI type.
2018-02-05 14:32:56 +11:00
Damien George f8922627d3 stm32: Update LCD and network drivers to work with new SPI API. 2018-02-05 14:32:56 +11:00
Damien George 4ad3ede21a stm32/spi: Provide better separation between SPI driver and uPy objs.
There is an underlying hardware SPI driver (built on top of the STM HAL)
and then on top of this sits the legacy pyb.SPI class as well as the
machine.SPI class.  This patch improves the separation between these
layers, in particular decoupling machine.SPI from pyb.SPI.
2018-02-05 14:30:32 +11:00
Damien George 4b8e58756b stm32/i2c: Allow I2C peripheral state to persist across a soft reset.
The I2C sub-system is independent from the uPy state (eg the heap) and so
can safely persist across a soft reset.
2018-02-02 19:04:36 +11:00
Damien George 5ddd1488bd stm32/spi: Allow SPI peripheral state to persist across a soft reset.
The SPI sub-system is independent from the uPy state (eg the heap) and so
can safely persist across a soft reset.  And this is actually necessary for
drivers that rely on SPI and that also need to persist across soft reset
(eg external SPI flash memory).
2018-02-02 19:01:11 +11:00
Damien George 57d2ac1300 stm32/rng: Simplify RNG implementation by accessing raw peripheral regs.
It saves code size and RAM, and is more efficient to execute.
2018-02-02 18:22:57 +11:00
Damien George 762db9ad2f stm32/spi: Add support for a board naming SPI peripherals 4, 5 and 6. 2018-02-02 17:44:05 +11:00
liamkinne 618aaa4a53 stm32/i2c: Use macros instead of magic numbers for I2C speed grades. 2018-02-02 12:15:05 +11:00
Damien George db702ba722 stm32/usbdev: Add support for high-speed USB device mode.
This patch adds support in the USBD configuration and CDC-MSC-HID class for
high-speed USB mode.  To enable it the board configuration must define
USE_USB_HS, and either not define USE_USB_HS_IN_FS, or be an STM32F723 or
STM32F733 MCU which have a built-in HS PHY.  High-speed mode is then
selected dynamically by passing "high_speed=True" to the pyb.usb_mode()
function, otherwise it defaults to full-speed mode.

This patch has been tested on an STM32F733.
2018-02-01 17:57:44 +11:00
Damien George 71312d0bd1 stm32/usb: Allow board to select which USBD is used as the main one.
By defining MICROPY_HW_USB_MAIN_DEV a given board can select to use either
USB_PHY_FS_ID or USB_PHY_HS_ID as the main USBD peripheral, on which the
REPL will appear.  If not defined this will be automatically configured.
2018-02-01 17:47:28 +11:00
Damien George 3130424b54 stm32/usbdev: Add support for MSC-only USB device class.

Damien George e8a8fa77ca stm32: Improve support for STM32F722, F723, F732, F733 MCUs. 2018-02-01 13:11:32 +11:00
Damien George 4e35d10829 stm32/can: Support MCUs without a CAN2 peripheral. 2018-02-01 13:11:02 +11:00
Damien George 583472e068 stm32/usbdev: Combine all str descriptor accessor funcs into one func.
There's no need to have these as separate functions, they just take up
unnecessary code space and combining them allows to factor common code, and
also allows to support arbitrary string descriptor indices.
2018-02-01 12:46:37 +11:00
Damien George 1d4246a2e8 stm32/usbdev: Reduce dependency on py header files. 2018-02-01 12:44:16 +11:00
Damien George fed1b4fb56 stm32/sdcard: Make SD wait routine more power efficient by using WFI.
Using WFI allows the CPU to sleep while it is waiting, reducing power
consumption.
2018-02-01 12:20:45 +11:00
Damien George c0496fd44d stm32/spi: Make SPI DMA wait routine more power efficient by using WFI.
The routine waits for the DMA to finish, which is signalled from a DMA IRQ
handler.  Using WFI makes the CPU sleep while waiting for the IRQ to arrive
which decreases power consumption.  To make it work correctly the check for
the change in state must be atomic and so IRQs must be disabled during the
check.  The key feature of the Cortex MCU that makes this possible is that
WFI will exit when an IRQ arrives even if IRQs are disabled.
2018-02-01 11:45:29 +11:00
Damien George efdda2c62d stm32: Add support for DHT11/DHT22 sensors. 2018-01-31 18:12:53 +11:00
