Quick answer for whose are in the same situation as me.I used examples from AN4666. I generated a clock signal with TIMx_CHy and used DMA on TIMx to retrieve data on IDR port (using masks). To stop the PWM clock as fast as possible, I set the CCMR re...

Hello, thank you for your answer ! I do not have access to the SPI pins of the STM chip. I have access to a pin assigned to TIM1 and a GPIO so I thought it would be a good solution to use the emulator presented on the AN.Also, I need to transfer 64 ...
