Weirdest thing happening with STM32H7 I2S hardware

[CLeo.1]

Hi guys! I am having the biggest issue with the I2S right now

What is happening: For whatever reason the I2S does not want to transmit any samples VIA DMA. Doesnt matter what I do what I try.

The weird thing happening: The I2S WS, SCLK wont work. Only if the DMA associated with the Tx part is enable (DMA1_Stream1) which I find so weird. All it does it set the WS pin to HIGH

What I have tried:

• Verified the registers are correctly setup
• Ensure with measuring tools the right signals are shooting out (WS, MCLK, SCLK) when the DMA1_Stream1 is enable
• Swapped out the ADC/DAC for another one
• Ensured the ADC is sending out its digital signal
• Ensured the STM32 is receiving samples and transmitting to the Tx Buffer associated with the DMA

How the code works.

The code waits around till an UART signal is received VIA the DMA, once received in goes into a super loop where it process UART signals

Depending on what UART signal was received it will enable not only the I2S peripheral but setup the clock, Interrupt, anything to make the I2S running with DMA etc...

Then the stm32 should now be ready to take in I2S signals and spit them out

Any help would be amazing, I am stumped right now its not even funny.

Oh sorry that was the old code, I can ensure you that RXDMAEN and TXDAMEN are set.

I tried to get it running without the DMA and still cant get it working.

@TDK​ Here you go king.

It's frustrating to look through code that is posted and find several errors, only to then be told that the posted code wasn't actually the code you used. You are not the only one, it happens more often than I would like. That's a waste of my time, as well as yours.

Its not your fault thats mine. I do apologize for that. If you have it in you, the latest code below this is the right one and is the one I am confident in. If you can spot anything in that that would be amazing.

If you cannot get something working, back off to a minimum. Make a simple polling pattern transmitter without DMA or even interrupts.

Fair enough, Would be able to look at my code and see if theres anything wrong https://pastebin.com/EFaLMLgR?
