This project demonstrates the implementation of a bidirectional SPI (Serial Peripheral Interface) communication between two STM32 boards: the STM32F407 Discovery Board acting as the slave and the ...

The Serial Peripheral Interface (SPI) interface was initially standardized by Motorola in 1979 for short-distance communication in embedded systems. In its most common four-wire configuration, ...

A race condition in the STM32 SPI driver can cause a permanent lockup when switching from TX to RX in half-duplex master mode. This issue was observed on an STM32H745 performing frequent 3-wire SPI ...
