Description

SPI Target mode for STM32, MIMXRT, and ALIF. This is the last missing interface for the machine module, bringing it up to parity with PYB more or less.

SPI-3 Wire and UART 1-Wire Support

port-stm32

I'm working on a new interface library for the OpenMV Cam and I thought these would be nice to haves:

Add support to the SPI bus to share MISO/MOSI. This feature is supported by the STM32 hardware.
Add support to the UART to share TX/RX. This feature is also supported by the STM32 hardware.
Add support to the UART for driver enable for rs485. This feature is also supported by the STM32 hardware.

Supporting these features involves setting a bit in the config register and then just configuring the I/O pins in slightly different modes.
