I want to share my related code and photo here. The program runs on an STM32F746 Nucleo Board. It uses timer 2 to trigger DMA1 stream 0 causing fixed-length transmission of data via SPI 1 to an external ADC without interrupts on the transmission sid...

The error comes from triggering the SPI NSS pin.First, I performed Hardware output Nss and saw that it did not write or read the register return value was 0. After Hardware I canceled NSS and turned it on and off with software. I wrote to the registe...

I defined buffer as volatile but there is no change. I can see debugging mode.first I configurated external adc register wrote and read the same register then set it to auto mode and started the sample with spi3.In addition ı don't use nss pin. I us...
