b178958c07 stm32/pendsv: Clean up pendsv IRQ handler and eliminate duplicate code. 2019-02-08 01:20:13 +11:00

1bcf4afb10 stm32/systick: Make periodic systick callbacks use a cyclic func table.
Instead of checking each callback (currently storage and dma) explicitly
for each SysTick IRQ, use a simple circular function table indexed by the
lower bits of the millisecond tick counter.  This allows callbacks to be
easily enabled/disabled at runtime, and scales well to a large number of
callbacks.

9dfbb6cc16 stm32/rtc: Get rtc.wakeup working on F0 MCUs.
The problem was that the EXTI line for the RTC wakeup event is line 20 on
the F0, so the interrupt was not firing.

f497723802 stm32: Allow to have no storage support if there are no block devices.
If no block devices are defined by a board then storage support will be
disabled.  This means there is no filesystem provided by either the
internal flash or external SPI flash.  But the VFS system can still be
enabled and filesystems provided on external devices like an SD card.

aa4a7a8732 stm32/usb: Guard USB device code with #if for whether USB is enabled.
With this change, all the USB source code can now be passed through the
compiler even if the MCU does not have a USB peripheral.

88c26a48b4 stm32/pyb_i2c: Put pyb.I2C under MICROPY_PY_PYB_LEGACY setting.
When disabled, the pyb.I2C class saves around 8k of code space and 172
bytes of RAM.  The same functionality is now available in machine.I2C
(for F4 and F7 MCUs).

It is still enabled by default.

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.

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.

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)

a3dc1b1957 all: Remove inclusion of internal py header files.
Header files that are considered internal to the py core and should not
normally be included directly are:
    py/nlr.h - internal nlr configuration and declarations
    py/bc0.h - contains bytecode macro definitions
    py/runtime0.h - contains basic runtime enums

Instead, the top-level header files to include are one of:
    py/obj.h - includes runtime0.h and defines everything to use the
        mp_obj_t type
    py/runtime.h - includes mpstate.h and hence nlr.h, obj.h, runtime0.h,
        and defines everything to use the general runtime support functions

Additional, specific headers (eg py/objlist.h) can be included if needed.

01dd7804b8 ports: Make new ports/ sub-directory and move all ports there.
This is to keep the top-level directory clean, to make it clear what is
core and what is a port, and to allow the repository to grow with new ports
in a sustainable way.
