MikeTeachman 6d5296e65e stm32,esp32: In machine_i2s, make object reference arrays root pointers.
This change eliminates the risk of the IRQ callback accessing invalid data.

Jim Mussared e359b077dd ports: Add board.json for all boards.
This will be used by https://micropython.org/download/ to generate the
full listing of boards and firmware files.

Optionally supports a board.md for additional customisation of the
download page, as well as deploy.md for flashing instructions.

Mike Teachman 8a5bfe44a5 esp32,stm32: Add new machine.I2S class for I2S protocol support.
This commit adds I2S protocol support for the esp32 and stm32 ports, via
a new machine.I2S class.  It builds on the stm32 work of blmorris, #1361.

Features include:
- a consistent I2S API across the esp32 and stm32 ports
- I2S configurations supported:
  - master transmit and master receive
  - 16-bit and 32-bit sample sizes
  - mono and stereo formats
  - sampling frequency
  - 3 modes of operation:
    - blocking
    - non-blocking with callback
    - uasyncio
  - internal ring buffer size can be tuned
- documentation for Pyboards and esp32-based boards
- tested on the following development boards:
  - Pyboard D SF2W
  - Pyboard V1.1
  - ESP32 with SPIRAM
  - ESP32

Mike Causer 47b778332a all: Replace busses with buses.
"buses" is the widely accepted plural form of "bus".

Damien George 120368ba1a stm32/boards: Enable LFS2 on PYBv1.x and PYBD boards. 2019-11-26 00:08:57 +11:00
Damien George 009b1f6559 stm32/boards: Rework all stm32??xx_hal_conf.h files to use common code.
This eliminates a lot of duplicated code in these header files.

Damien George 9670b26526 stm32: Rename MICROPY_HW_HAS_SDCARD to MICROPY_HW_ENABLE_SDCARD.
For consistency with the majority of other MICROPY_HW_ENABLE_xxx macros.

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 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.

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 34911f1a57 stm32/boards: Update all boards to work with new USB configuration. 2018-02-13 18:57:01 +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.

Damien George 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.
