DAC3283EVM-SW: How to configure SPI registers w/o GUI offered by TI

Part Number: DAC3283EVM-SW
Other Parts Discussed in Thread: DAC38RF82EVM, LMK04828, LMX2582, ADC12DJ3200EVM, DAC38RF82

Hi Ken C. or alternate High Speed Data Converter application Engineer,

I would like to communicate directly with the DAC38RF82EVM as part of a MATLAB automation script.  In a 25 July 2015 forum thread between  and Ken C., Ken mentioned there were some tools available for Labview and MATLAB to communicate with the DAC using the on-board FDTI USB <=> Parallel interface.  Can someone please provide me such tools for the DAC38RF82EVM? 

I've already downloaded and trialed a similar set of tools for the ADC12DJ3200EVM, which allowed me to load  .CFG files for the ADC, the on-board LMK04828 & LMX2582 RF synthesizer.  It seems to work pretty well for that EVM,  I would be most grateful for a similar MATLAB "tool-kit" for the DAC38RF82EVM.

Much Thanks,

Steve Krupa

  • Hi Steve,

    You can refer to the link below for the Labview based DLL tool to incorporate the SPI write/read tool into your automation software.

  • Hi Kang,

    Thanks for your prompt reply.  For me, the "missing piece" of the equation for automating the initiialization/ startup of the DAC38RF82EVM is the "FTDI Pattern File" you identify in your "DAC348xEVM_Labview_SPI_Software.PPTX" document.  For the DAC3484xEVM, this file is named

    DAC348x.txt

    We just need the same kind of file, with the register settings configured for the DAC38RF82EVM.  I am using an SPI programming script in MATLAB for the ADC12DJ3200EVM (downloaded from the "Software" tab of the product page, as part of an MATLAB Automation installation package) which uses a similar  file (ADC12DJxx00.txt).

    If you can send me the "DAC38RF8x.txt" file for the FTDI USB-to-serial converter on the DAC38RF82EVM board, I should be able to handle it from there.  

    Much Thanks,

    -steve

    PS:  If you don't manage to track down a DAC38RF8x.txt file, do you think I could use the DAC348x.txt file you provided in your previous post for that particular DAC product?

  • Hi,

    These are called pattern files, which lists the clock and data patterns on the SPI bus for the particular device. You can download them from the software packages of the EVM within the "pattern file" folder. Below are all the files in the DAC38RF8x EVM software pattern file:

    "C:\Program Files (x86)\Texas Instruments\DAC38RF8x GUI\Pattern Files"

  • Hi Kang,

    These files are just what I needed, much thanks for this.  After your  email, I confirmed that these files were available in the directory on my lab PC.  I guess I should have checked there first... :)

    I may have some further questions, if the behavior of the DAC doesn't line up with my expectations after I use the pattern files to load the desired information (i.e. the previously defined & saved .CFG configuration file)  into the DAC.

    Thanks Again,

    -steve

  • Steve,

    I will close this post for now. For questions regarding the DAC38RF82, you may open up new posts with specific title related to the questions and we can answer accordingly.

    thanks.
