How to trigger SPI DMA transfer using TIM12 TRGO on STM32H7

[sumeyyekaragul]

Hi everyone,

I'm currently working with the DMA concept on an STM32H7. I'm reading data from an FIFO via SPI. My goal is to trigger the SPI DMA transfer using TIM12 TRGO, but I’m not sure where to start or how to properly configure this connection.

I’m relatively new to this topic, so any guidance, examples, or tips on how to set up the timer trigger and link it to the SPI DMA would be greatly appreciated.

Thanks in advance for your help!
