DLP6500FYE: Run-Length Encoding Function for 8-bit Image

Arynn Gallegos
Prodigy 10 points
Part Number: DLP6500FYE

I am looking for a function to perform enhanced run length encoding (RLE) of 8bit images for the DLP LightCrafter 6500. I would like to use the output of the function to upload the image on the DMD using the "PATMEM_LOAD_DATA_MASTER" command. Is there an encoding function I can use, preferably optimized for Python?

Thank you!

    Hi Arynn Gallegos,

    We don't have python function for RLE Encoding.

    You can look at Source code of GUI located at install directory.
    C:\Texas Instruments-DLP\DLPC900REF-SW-4.0.1\DLPC900REF-GUI\Sources

    C language function for RLE encoding is present here. Function "RLE_CompressBMPSpl()" in file compress.c does the Job of enhanced run length encoding (RLE).
    C:\Texas Instruments-DLP\DLPC900REF-SW-4.0.1\DLPC900REF-GUI\Sources\HiresLib

    GUI is build using QT Creator. 

    Thanks,
    Shivakumar
