EzDSP ADC

Avvi
Prodigy 30 points

Hi,

I'm trying to get the ADC going on EzDSP. I set up everything as per the application note and once the busy flag is cleared I read the data. For some reason the data is always 0xff even i ground the input pin (GPAIN0).

Does anyone have some sample code that could be help.

Any help very much appreciated.


Regards

    Hi Avvi,

    You should check out the example projects included in the C5505 Chip Support Library.

    For C5505 eZdsp, you need to download C55XCSL-LOWPOWER from http://focus.ti.com/docs/toolsw/folders/print/sprc133.html

    Once installed, the following three ADC examples will be located under <install path>\VC5505_CSL\CCS_v4.0_Examples\sar\ :

    CSL_SAR_DmaExample
    CSL_SAR_IntcExample
    CSL_SAR_PollExample


    These projects should get you started with the ADC. Please be sure to read the Release Notes that get installed with the CSL for CCS4.0 usage instructions.

    Let us know how it goes.

    Thanks,
    Mark
