Question
STM32F401 SPI CLK turns off with DMA
Hello
Got a weird issue, to further test I created blank project with no other code to rule out conflict.
When I put in
HAL_SPI_Receive_IT(&hspi3, SPI_RX_BUF, 2);
,According to my logic analyzer, the clk and data pins stay high and dont move.
When I comment it out the clk and data pins move correctly.
I've turned on the DMA and have it configured correctly I believe. Im using this chip to talk to a H7 and that chip receives data , when the dma is off, no problem and I have this DMA configured in the same way.
I have the h7 disconnected for testing purposes.
I've tried everything I can come up with and I'm completely lost and out of ideas.
