SPI communication (Transmit Only Slave)

[pass3master]

We are trying to develop a device that uses SPI communication (Transmit Only Slave).

Are there any sample programs for SPI communication (Transmit Only Slave)?

What should be the trigger for calling HAL_SPI_TransmitReceive? Master's CS?

Hello @pass3master ,

I recommend you to take a look at these examples may help you:

• SPI_FullDuplex_ComPolling_Slave
• SPI_FullDuplex_ComDMA_Slave

These examples have been tested with NUCLEO-H503RB board and can be easily tailored to any other supported device and development board.

For more information about the SPI communication, please refer to RM0468 sections 55.4.3 SPI communication general aspects and 55.4.4 Communications between one master and one slave.

I hope this help you.
