SPI with STM32 

بسیار عالی. لطفا باز هم ویدیو های آموزشی بذارید

Nice ❤❤❤❤❤❤❤

when i connected this way in hardware board , its showing target is not connected,why? pls help

I have a question, in your code, you initialized PIN A4 (SPI1_NSS) as GPIO output with initial value of "low" and connected this pin to PB12 (SPI2_NSS), does this mean the NSS is always pulled low and the SPI protocol is always transmitting?

Thanks a lot!!!
