28c9824c51 stm32/boards/NUCLEO_H743ZI: Enable ADC peripheral. 2018-05-01 15:39:03 +10:00

8c12f1d916 stm32/adc: Add support for H7 MCU series.
ADC3 is used because the H7's internal ADC channels are connected to ADC3
and the uPy driver doesn't support more than one ADC.

Only 12-bit resolution is supported because 12 is hard-coded and 14/16 bits
are not recommended on some ADC3 pins (see errata).

Values from internal ADC channels are known to give wrong values at
present.

999c8b9711 esp32/modsocket: Add support for registering socket event callbacks.
The esp8266 uses modlwip.c for its usocket implementation, which allows to
easily support callbacks on socket events (like when a socket becomes ready
for reading).  This is not as easy to do for the esp32 which uses the
ESP-IDF-provided lwIP POSIX socket API.  Socket events are needed to get
WebREPL working, and this patch provides a way for such events to work by
explicitly polling registered sockets for readability, and then calling the
associated callback if the socket is readable.

527ba0426c stm32/system_stm32: Reconfigure SysTick IRQ priority for L4 MCUs.
After calling HAL_SYSTICK_Config the SysTick IRQ priority is set to 15, the
lowest priority.  This commit reconfigures the IRQ priority to the desired
TICK_INT_PRIORITY value.

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.

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.

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.

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.

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.

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.

0096a4bd00 tests/pyb/adc.py: Fix test so that it really does test ADC values.
Reading into a bytearray will truncate values to 0xff so the assertions
checking read_timed() would previously always succeed.

4ff05ae4e9 esp32/machine_uart: Remove UART event queue object.
This event queue has UART events posted to it and they need to be drained
for it to operate without error.  The queue is not used by the uPy UART
class so it should be removed to prevent the IDF emitting errors.

Fixes #3704.

ef12a4bd05 py: Refactor how native emitter code is compiled with a file per arch.
Instead of emitnative.c having configuration code for each supported
architecture, and then compiling this file multiple times with different
macros defined, this patch adds a file per architecture with the necessary
code to configure the native emitter.  These files then #include the
emitnative.c file.

This simplifies emitnative.c (which is already very large), and simplifies
the build system because emitnative.c no longer needs special handling for
compilation and qstr extraction.

Keeping all the stress related tests in one place makes it easier to
