I meant to say the DSP processing is fully working!! Not with a question mark.

Can't see an edit post option on this forum. That's a shame.

Awesome you got it working - sucks about the firmware problem tho.

There is a edit option - it's a little pen next to the flag on the top right of anything you post.

Have fun!

fully working in Stereo !!!! :D :D :D :D

The hardware was fine , you were correct , i needed to de-interleave I2S

int16-t to float -> de-interleave -> DSP L & DSP R -> float to int16_t -> re-interleave !!!

I untangled the code from equaliser.c so its own thing and called is dsprunner.c

awesome , super happy , thanks for your tips !! :D :D :D :D
