Hi all,
I bought for DSP Analog Prototyping Board. I tried all the exercise and everything is fine. Now i want to get the data from the CODEC and analyze it in microcontroller. From the exercise there are does not have an example to do it. I tried to change the source code, but until now i did't get anything, please, who tried it before.... can we share?  |

This forum is for Microchip products and the CCS compiler (which is produced for use with Microchip products.)
You would be best to look for the TI users forum to ask such question.
Cheers,

Someone mentioned to me there is a driver for that particular TI CODEC, but you haven't told us what compiler you're using or Microcontroller.
If those are Microchip/CCS based products, we *might* be able to help if the problem is specific to Microchip/CCS.
However, if it's specific to the TI320, you would still probably be best helped in a TI forum.
Cheers,
-Ben

Thanks Ben, I bought the DSP Analog Board from CCS ( http://www.ccsinfo.com/product_info.php?products_id=dsPIC-analog-kit ). The compiler also I'm using PCD compiler from CCS. The last exercise we store the data into MMC card, but I need data that coming out from TI320 (Dout)... As I know, we need to configure to I2S protocol, I tried for both HARDWARE (PIC and TI320), and I don't know where the data are. I tried dci_read(), but from the compiler manual it should go to dci_read(left_channel, right_channel), but when we code it, the error is come out, we need to put ONLY dci_read(). Please advise. |

Can you verify the data you want is coming off the card?
From there, is there a test pattern you can generate in test function that you can see being transferred over SPI (you do have an Oscilloscope, right?) to the 320?
There's a lot of simple debugging you could be doing... have you done it?
