C6713DSK + ADS1606EVM Design Files

Other Parts Discussed in Thread: ADS1605

Hello all,

My name is Justin Burk and I am attempting to get back into DSP. I took technical and lab DSP courses in college but haven't seen it since 1998. I have spent the past 12 years designing RF/Microwave hardware (primarily for space based radar and satellite communications systems) and programming in C#. I was involved in developing algorithms for DSP and FPGA's but I wasn't actually writing the code in C for the DSP. I recently purchased the C6713DSK, 5-6K adapter, and the ADS1606EVM. I chose the 1606 because it was one of the ADCs with the highest speeds at 16 bits that can be connected directly with the DSP chip without needing an FPGA as glue logic (one step at a time!). Also, the datasheet references a design example which integrates the C6713DSK and the 1606. However, I can't find the design examples anywhere in the CCS install directory. I am using the CCS version (3.1?) that came with the DSK. I did manage to find a post here on the forum where someone supplied the design files. I can re-build the project but when I try loading the program I get an error from CCS that the RTDX library used by the program is an older version than that on the chip. Can someone please tell me how to fix this or supply a more recent version of the ADS1601-C6713 reference design? Thanks in advance for your help. The learning curve for re-learning C has been greater than I expected! I'm still gathering reference materials and designs to help me get up and running quickly.

    Which datasheet?

    Can you expand on the exact error? Is there any error codes?

    CCS 3.1 is very outdated. You might want to consider updating  to (at least)  CCS 3.3 to take advantage of any bug fixes / features added.

  • Hello Drew, thank you for the response.  The datasheet I'm referring to is actually the user's guide for the ADS1606EVM, located here:

    http://focus.ti.com/lit/ug/slau122a/slau122a.pdf

    On page 4-3 of the document, which corresponds to page 25 of the pdf, it states:

    For the TMS320C6713 DSK: Open ADS1605−C6713.pjt

    As stated before, the project builds just fine, but after attempting to load the program, the error message states: "RTDX target application does not match emulation protocol!  Loaded program was created with an rtdx library which does not match the target device.".

    There are no error codes.  I'm just trying to follow the directions for acquiring data from the ADS1606EVM per the user's guide.  Thanks again for your help.

     

  • Justin,

    The user guide was written way back in 2004! CCS has undergone some fundamental changes since then, most notably the move to an Eclipse based framework.   You may wish to post on the corresponding forum for ADS1605 to see if there are any updated User Guides / sample software.
