Hello,I'm testing the SPI peripheral through a simple PDM mic. The problem is the SPI doesn't start at all. The CSTART bit (that is the one that start the transfer) remain cleared, even right after I SET the bit.Now, I noticed that just after I've do...

Thanks for the answer. I know the H7 is overcomplicated!I don't have an oscillator yet but I tested the I2S which share the same pinout configuration. The thing that concern me most is the fact that possibly the bit clock isn't generate properly.May ...

Also I checked the I2S peripheral and it worked fine. Same pin configuration though.

This is my set up: The intend to test the various operation modes: polling, IT, DMA.. Already tried all of them but got the same issue. By now I'll be happy to see it functioning just in the polling mode, for this I'm using HAL_SPI_Receive(&hspi1, bu...
