Hi there I working with the 21160 proccesor, and would like to initialize the codec(AD1881A) in assemble language. I can only find such program written in C. Does any of you have source code in assembler, or even better a core that set up the whole board like the traditional 21065L source code, with variable samplerate ? Best regards Thomas |

It was written for the 218x family and works AC-97 Version 2.1 compliant codecs. This means it doesn't rely on ADI's Slot 16 mode. The following features are supported: 1. One AC-97 codec running as a master. 2. Variable Sampling using the Data Request Bits. 3. AC-97 Commands and Response Handler. We actually wrote the 218x driver from some earlier code written for the ADSP-21065L. If there is interest, we can rewrite the code for the Sharc. The original Sharc code just needs some cleanup. All of our code is in assembly. I assume that you have read John Tomarakos' application note published on the ADI site. For those who wish to write their own driver, it is a good place to start.
