I can use the modified csl i2s polled example to read stereo an write stereo
( read music media player and rewrite to play thru the sound card).
My objective is to read the output from SDR IF output, filter, demodulate and out put to stereo output.
I removed all the code in the .c file that had nothing to do with polled stereo.
I modified the CSL_I2S.C code, I2S Read and I2S Write. the major problem was the latency code. It went negative
and never got to the positive number in the while code.
