Trying to get I2S running to have Audio Output

[anyn99]

Hi everyone,

I am in the process of implementing this library into openHASP:
https://github.com/schreibfaul1/ESP32-audioI2S

I had to do some stuff to make it fit, because it's using the new IDF, but that is a different story ;-)
The board i am using is esp32-s3-4848s040_16MB.

What i really wanted to ask is, if someone has tried anything similar?
I tried running the task which is feeding the I2S on both core 1 (LVGL is also using this as i understand) and core 0 (default for all other tasks if i understood correctly?)
The display shows some odd flickering and I wonder if this is due to I2S clock lines maybe? Or does it have to do with task switching?
I read somewhere that there were indeed some display flickering problems sometime with some other feature, but i can't find what it was?

Anyone who has a clue is greatly appreciated. If this works out i try to submit a pull request to get audio support into openHASP, anyone interested in this?

greetings,
Daniel
