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, ...
STM32 SPI library has been modified with the possibility to manage hardware CS pin linked to the SPI peripheral. We do not describe here the SPI Arduino API but the functionalities added. User have 2 ...
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 ...
