DLPDLCR160CPEVM: File name for DLP

Part Number: DLPDLCR160CPEVM

Hi - I've received my DLPDLCR160CPEVM, but I can't get any pictures to shown from the SD card. I've got a 4Gb card. I've only put 1 file on it (now). I've resized the image to 640x360 and used https://longfangsong.github.io/en/image-to-rgb565/ to convert to RGB565. Does the file need to have certain extension? It's currently RGB565.bin

    Hello Mark,

    Welcome to the E2E forum. Thank you for your business!

    Just to confirm, you have followed these steps:

    1. Do not have the EVM plugged in or powered-on.
    2. Insert the SD Card into the EVM.
    3. Plug in the EVM to a power supply.
    4. Toggle the PROJ_ON switch to the on-state.
    5. Navigate to and select the the SD card option using the push button.

    The EVM currently does not playback content from the SD card if the SD card is inserted after power is supplied to the EVM. 

    Best,
    Maxine

    Hi Maxine

    Yes, I have followed those steps. 

    Holding the button for ~5 seconds shows "SD card images mode \r\n Long press to return to menu". No images are shown. A short press changes it to "In SD card mode... \r\n Long press to return to menu". No images are shown.

    So the file that I can see in the message above (Alpha0.bmp) we converted to Alpha0.raw, which should be RGB565 encoded, although I cannot see it attached.

    Hello Mark,

    Exact details on how to configure the SD card for EVM playback in the SW Programmer’s Guide will be released soon.

    What you are missing the conf.txt file, which specifies a set of parameters for each image, such as the image file name, draw coordinates, background color, and time to display.

    Here is a zip of what you should load onto your SD card as an example. This zip has one .txt file and four .bmp files.

    It is important that you do not change any of the file names, especially the conf.txt file since this is the root file the MSPM0 seeks to execute the SD card playback.

    Only 24-bit .BMP images at 640x360 resolution are supported; you cannot use .PNG or .JPG files.
