An example of SPI communication from an STM32 master to an Arduino slave Ignore the basic_leds project names, I didn't want to deal with refactoring the name throughout the whole project and makefile ...

static HAL_StatusTypeDef SPI_WaitFlagStateUntilTimeout(SPI_HandleTypeDef *hspi, uint32_t Flag, FlagStatus State, uint32_t Timeout, uint32_t Tickstart); static HAL_StatusTypeDef ...

To prevent data corruption when using multiple SPI devices on the same bus, care must be taken to ensure that they are only accessed from within the main loop, or from the interrupt routine, never ...

Abstract: According to the characteristics of the STM32 technology and DeviceNet fieldbus, this paper designs a DeviceNet - SPI converter module. The converter module solves the problem of conversion ...
