In case anyone was curious, I resolved my issue. MCLK was not configured properly. I now have WAV files playing using a TI TLV320AIC23B codec. Yippie! 🙂

I am trying to use SPI2 in I2S mode on a STM32F103RE (this one has I2S) and I am having some trouble. I believe I have all of the clocks configured correctly, as well as the peripheral configuration. In a nutshell, here's what happens:

I write a byte to SPI2_DR. The TXE flag gets cleared, but BSY never gets set and TXE never gets set again. It feels like nothing is getting clocked out.

In my configuration, I am operating as the I2S master, and the master clock is enabled. Any ideas? I just want to hear a chirp. 🙂
