I know this should be a simple part, however I have been unable to make this work.
I am using I2S output from STM32F103, 22050 16bit. I have verified by scope the SCK, BCK, LRCK, and DATA.
All the edges line up properly and of the proper phase. I was not sure if my commands were being accepted by the Control port so I write nothing, assuming the stated defaults are correct. thus the part should be active and able to decode the data provided. Everything on the scope looks correct, but nothing changes on the outputs. I am using the data empty interrupt to keep the pipeline full and I get a continuous stream of all appropriate clocks and data. I get silence out of the part. When I start and stop my code I do get a "pop" so something is working, but no matter what data I write I get nothing. Even if the data was backwards I should see some change in the output since I am filling up all 16 bits with a sawtooth. and I am looking at the analog output and was expecting an appropriate level based on the data fed into that channel.
Any suggestions?
Thanx
