Damien George aa7de3ff67 stmhal: Move L4/F7 I2C timing constants from mpconfigboard.h to i2c.c. 
Such constants are MCU specific so shouldn't be specified in the board
config file (else it leads to too much duplication of code).

This patch also adds I2C timing values for the F767/F769 for 100k, 400k
and 1MHz I2C bus frequencies.

Rami Ali 27a503f632 stmhal: Refactor UART configuration to use pin objects. 
This follows the pattern of other peripherals (I2C, SPI) to specify the
pins using pin objects instead of a pair of GPIO port and pin number.  It
makes it easier to customise the UART pins for a particular board.

Damien George b4cc68e4a4 stmhal/led: Refactor LED to use mp_hal_pin_output() init function. 
As part of this patch the MICROPY_HW_LED_OTYPE setting is removed because
it is now unused (all boards anyway had this as OUTPUT_PP).

Dave Hylands fedab995ee stmhal: Set STM32F7DISC CPU Frequency to 216 MHz 
This set the CPU frequency to 216 MHz (the max) and
leaves the USB Frequency at 48 MHz.

These settings were copied from one of the HAL examples.

Paul Sokolovsky 97a0846af9 stmhal/diskio: Introduce MICROPY_HW_HAS_FLASH setting. 
To allow to reuse stmhal/diskio for ports which don't have flash but have
other storage devices.

Fabian d0f31ccf33 stmhal: Change PLL configuration for STM32F7DISC. 
Changes USB clock from 50MHz to 48MHz which improves USB communication.

Damien George f7c4f9a640 stmhal: For SPI config, use HW_SPIx_SCK instead of HW_ENABLE_SPIx. 
Previously, SPI was configured by a board defining MICROPY_HW_ENABLE_SPIx
to 0 or 1.  Now, the board should define MICROPY_HW_SPIx_SCK, MISO, MOSI
and NSS.  This makes it the same as how I2C is configured.

Dave Hylands 823a961ecc stmhal: Enable sdcard on STM32F7DISC board. 2015-10-30 12:05:14 +00:00
Dave Hylands 5e11d2b349 stmhal: Enable SPI support for F7 MCUs. 2015-08-05 23:38:49 +01:00
Dave Hylands 34fe5a30c6 stmhal: Enable I2C support for F7 MCUs. 2015-08-05 23:38:24 +01:00
Dave Hylands 8f1eced69d stmhal: Add STM32F7 support for USB serial and storage. 
USB serial is now working for F7.

Internal file storage is now working for F7.  The flash is laid out a bit
differently to the F4 - 4 x 32K, 1 x 128K with the rest 256K, so the
internal storage is 96K.

Added more pind definitions for STM32F7DISC board.  Made USART1 be the
default HWUART repl.  The STLINK usb connector also looks like a USB
serial port which is attached to USART1 on the STM32F7DISC.
