Hello, 

Please could someone post the details to manage the SPI NSS signal? The master drives it "manually" using a GPIO bit. I want to use the SPI as a full-duplex master (sending and receiving data simultaneously). In the Slave side, I want to use the hardware slave select pin because I want to avoid using need an external interrupt to handle it.  I have read many posts about the NSS deficiencies in the STM32 implementation and when I have tried to make work, I didn’t success  

 

Thanks in advance
