Hi, I understand that the c5510 DSK uses a AIC23 stereo codec for input and output of audio signals. However if instead of feeding an analog input signal, can I feed in an array of digital inputs from the processor to the codec so that it can be converted into analog signals? Do I need to use McBSP to transfer my array elements to the codec? I would appreciate if anyone can provide with simple codes. I have tried looking for information but I have no idea how to handle the McBSP and to link it between my array and the codec. Thanks. |

How do you think that the data goes back, out of the CODEC? It's a stream of digital data, transmitted from the DSP to the CODEC, specifically to the onchips DAC. > Do I need to use McBSP to transfer my array > elements to the > codec?

Let's assume that you have some interrupt servicing routine where you get the received data and then send processed data back to the CODEC for ditigal-to-analog conversion. Well, insert the data you want to convert to analog RIGHT HERE! JaaC __________________________________________________ |
