TMS320C5517: Audio processing

Nancy Wang

Part Number: TMS320C5517

Hi,

The customer bought the tmdsevm5517. But the demo can only test AIC3024-1 or AIC3024-2 independently. He wants voice input from mic1 and output from p8 and p9 at the same time. I have checked the schematic and that can realized throguh codec2, am i right? How to configure in programming?

Nancy,

Which demo are you talking about? Is it a specific TI design?

If its a general question on routing the audio from codec 1 to codec 2, you can consider looking at the below setup.

Have not tried this before but the idea is that you want connect the U19 codec 1 output I2S to the input of U72 codec 2 input.

Please see J28 pins 2 & 3 on the EVM. As long as your SW initializes and the I2S BCLK and WCLK is being fed into both codecs, it should work.

Hope this helps.

Hi,That'a my question.I don't know too much about TMS320C5517.So,the question is I don't know how to do the SW initializes.Below is the test code for aic3204-1and aic3204-2.

How can I meet the requirements.

Nancy,

My recommendation is to start by using this example that's in the CSL
C:\ti\c55_lp\c55_csl_3.08\ccs_v6.x_examples\i2s\CSL_I2S_AudioCodec_DMA

If you look at C:\ti\c55_lp\c55_csl_3.08\ccs_v6.x_examples\i2s\CSL_I2S_AudioCodec_DMA\AudioCodec_DMA.c the I2C setup has 2 instances setup. Each AIC is on I2C0 and I2C1.
So, could you try to get the example to work with each individual AIC first?
Then try to combine the two.
