WebApr 10, 2024 · So as far as I can tell, the Hardware NSS output should only be used if you’re using a single device, I don’t think the SPI peripheral can handle multiple hardware chip-selects. What can be done for multiple devices on a single bus is to use Software NSS, and then manage the CS lines outside of the calls to the SPI Rx/Tx commands. http://efton.sk/STM32/gotcha/g21.html
