DLPDLCR2010EVM: How to read firmware?

Part Number: DLPDLCR2010EVM

Hello i'm using DLPDLCR2010EVM

I'm going to update my own firmware. Because I want to change keystone.

So I make batch files by reading 'DLPC343X Software Programmer's Guide'.

But I think it is not running perfectly so I want to get Firmware's batch files which you provide (DLP LightCrafter 2010 Firmware) and compare with mine.

Is there any software I can open and read Firmware's batch files??? (I mean Firmware is disk image file so I have no idea how to open.)

And I want to Factory Initialization because when I turn on DLP lightcrafter with your firmware It is not working normally(The flash image comes out for a while and then it goes out. )

Sincerely

Jang.

  • Jang,

    Which version of the LightCrafter Display GUI are you using? Furthermore, what batch files are you attempting to run on your system? If possible, please share more information about what you are trying to do with batch files on your system so we can assist you further.

    Best Regards,
    Philippe Dollo

    Dear. Philippe Dollo 

    I'm using DLP LightCrafter Display v7.0 for control my DLPDLCR2010EVM.

    And I want to run Keystone Correction Control enable and projection Pitch Angle in -4.95

    Display size and Image Size in 854X480. That's all I want to do.

    I don't want to change anything except those described above.

    I'd like to make sure it's in the same state as it was at the beginning.

    Yours sincerely.

    Jang.

    Hi Youngsoo,

    Are you getting any errors while updating flash image? If not, is the flash image generated successfully? If so, are you able to download the updated flash image onto the EVM? Are you able to display anything?

    Please let me know what issue you're facing while updating batch file so that I can give you step-by-step instructions on how to do the same.

    When I first connect the power to DLP and switch on, the flash image comes out for a very short time and never comes out again.

    If it is connected by HDMI, external images are produced.

    However, if not connected, press the <display settings push buttons> on the DLP board to get the flash image.

    Now, the batch file that I created has disappeared, leaving only the firmware image file.

    So I made another batch file, which does not print not only flash images but also external images.

    # Write: KeystoneCorrectionControl

    # Write: ProjectionPitchAngle

    # 100 ms delay
    W 36 DB 64 00
    # Write: ImageOrientation
    W 36 14 00

    I'd appreciate your help.

    Hi Youngsoo,

    Do you want to use splash screen or external input, or both? The batch file commands are not arranged in a correct manner. Depending on what input you require, I can guide you in writing the batch file.

    You mentioned that external input worked while using the earlier batchfile? In that case, was the keystone correction successfully applied?

    Regarding the new batch file you've written, may I ask what prompted you to add the 100ms delay?

    Regards

    Hi Azad

    I want to use both splash screen and external input.

    And, Yes It worked while I use earlier batchfile also keystone correction was successfully applied!

    But I want to change Keystone adjustment often because I have to adapt to the situation.

    Acutually I just copy batchfile example in GUI Tool users guide which you distribute.

    Regards

    Jang

    Hi Youngsoo,

    Here are some general guidelines to follow while writing batch files:

    • Set the input image and display size first, followed by the input source.
    • If splash screen is selected, splash screen execute should be the last source associated command.
    • Enable LEDs as the last command, add your custom commands before that.

    Here is the batch file you need to use:

    ## Write: ImageCrop: 520x320 = 0x0208 x 0x0140

    W 36 10 00 00 00 00 08 02 40 01

    ## Write: DisplaySize: 854x480

    W 36 12 00 00 00 00 56 03 e0 01

    ## Write: InputImageSize: 520x320 = 0x0208 x 0x0140

    W 36 2e 08 02 40 01

    ## Write: Splash screen select ; 00 = First Splash screen

    W 36 0D 00

    # Write: InputSourceSelect; 2 = Splash screen

    W 36 05 02

    ## Write Splash screen execute

    w 36 35

    # 100 ms delay

    w 36 DB 64 00

    # Write: KeystoneCorrectionControl

    W 36 88 01 00 01 00 00

    # Write: ProjectionPitchAngle

    W 36 bb 0d fb

    # Write: LedCurrent

    W 36 54 07 01 07 01 07 01

    # Write: WRITE LED ENABLE = 7. DISABLE = 0

    W 36 52 07

    To change the keystone angle multiple times during run-time using GUI, you can store each keystone configuration as a batch file on your PC and run the required batch file using Run Batch File option in the Advanced GUI.

    Azad
