OMAP-L138 EXperimenter Kit

Other Parts Discussed in Thread: TLV320AIC3106

Hi

I am interested in purchasing an OMAP L138 Experimenter . But i need the clarifications for the following,

1. Can we have onboard emulation for C6748 DSP core of OMAP L138 using CCS v3.3 provided along with Experimenter kit or Do we need to purchase any JTAG  emulator

2. Are we getting any sample programs to initialize TLV320AIC3106 codec so that we can implement real time Filters like, FIR , IIR and adaptive filters

3. for implementing Adaptive fiters we want to input two different signals of diffrent frequencies with in audio rrange. for this can we use the onboard stereo connectors.

Looking forward to your replies,

Thanks & Regards

    You can connect to the EVM board with the CCS that comes with the board without a problem.

    You can't make use of the DSK version of CCS 3.3 that ships with our kits on a custom target board. One of the main reasons is that it doesn’t support external emulation. It won't give you that option. Among other reasons, if you begin to develop, and want a newer chip, or even any of the other features and plug-ins of CCS, you wouldn’t be able to use them as all of the updating functionality is removed from the DSK CCS3. One would have to purchase the full version of CCS3 for this.

    For CCSv4, there is a free version that will work with the XDS100 external emulator. Please see Bundle License at: Free Licenses

    Please see:

    http://tiexpressdsp.com/index.php/Getting_Started_Guide_for_C6748

    If you install the software in the default path you can find the audio project at:

    C:\Program Files\Texas Instruments\pspdrivers_01_30_00\packages\ti\pspiom\examples\evm6748\audio\build

    Also, you can get the Board Support Library at LogicPD website clicking at Kit Contents. You do not needto have a board but you need to have an account in LogicPD's website. See the audio test at:

    ...\evmomapl138_v1\tests\experimenter\audio\ccs

    You could somehow adapt an audio cable and have different audio in the left and right channels.

    In the project:

    C:\Program Files\Texas Instruments\pspdrivers_01_30_00\packages\ti\pspiom\examples\evmOMAPL137\audio\build\ccs3\audioSample.pjt

    You would process the buffers in the file audioSample_io.c, function Audio_echo_Task. 16 bits of each sample in the buffer are going to be left channel and 16 bits are going to be right channel.
