Hi all,I'm currently working on a STM32H743. The idea is to use a SAI peripherals to read an Audio stream:The SAI is set to be a Master receive with a circular buffer and a DMAThe issue is that as soon as the HAL_SAI_Receive_DMA is called, then the c...

Hi all,I have a STM32F765, which i want to use to generate 4 D-shot signals on 4 GPIO, in the specific 4 gpio connected to Timer 1 .The timer is set as 4 channel pwm with DMA (memory to perpheral).The issue is that i'm able to generate the desired si...

The problem was mostly related to a not deep understanding of the dma. About the D-Shot, it doesn’t really matter. I will change the title of the thread with generic buffer, instead of d-shot!

This answer my question. Thanks.I used dma2 stream 1,2,4,6!

A dshot is a digital protocol used to transmitt commands to motor’s ESC.For more information, have a look to this link https://os.mbed.com/users/bwest32/notebook/dshot/

Does it mean that with dma2 stream 6 channel 0, it is possible to use only one channel between CH1,CH2,CH3? In that case i can consider this thread close :)

The issue has been temporary solved using different dma streams for each timer channel!
