DLP3010EVM-LC: How do you make the unit startup up in a mode besides external video using the batch file

TomC

Part Number: DLP3010EVM-LC
Other Parts Discussed in Thread: DLPC3478

Tool/software:

I have been able to modify a batch file to set led current and other functions at startup. 

My goal is to have it start in external pattern mode but this does not work via the batch file at starup. The command is always ignored. What causes it to go into external video mode at start if that is not in the file? Is there anyway to change the startup mode to a pattern mode. I can run a batch file to do this and it works it, just not at startup.

    Thanks for reaching out through E2E!

    Hello

    Is there any information about how to set the unit startup mode?

    Hello TomC,

    Sorry for the delayed response, that is my fault.

    If you want to change the startup settings, it requires a firmware update.

    There is an alternative way to change the settings after powering up by using I2C commands, and you can find the details in the DLPC3478 Software Programmer's Guide. There will be a slightly slower startup due to waiting for PROJ_ON to pull low before communication, but this is a workaround.

    Please advise, are you developing systems in mass for consumers?

    Best,

    Aaron

    Is this a different firmware than the one available for download from the product page? I have flashed the firmware with a batch file as shown in examples. All the commands I have added to the auto initialization batch file in firmware execute properly except for the operational mode command. 

    # 0x96 - Pattern Configuration
    W 36 96 00 01 01 00 01 00 00 00 01 00 00 00 02 00 00
    # 0x05 - Operating Mode Select
    W 36 05 03

    Regardless of the order I place them or where in the batch file they are the unit starts and goes to external video operational mode. I have tried adding delays and other tips I have found on the forums but without success. 

    I am developing for existing manufacturing equipment for marking purposes. The device generating the external pattern stream is not capable of i2c or usb communication. To test on exisiting operational equipment for developing the prototype, I need the unit to be able to go into the correct operational mode at startup without external commands.

    Hey Tom,

    Any time there is a response in this thread, I will be automatically be notified.

    If it requires a firmware update, yes the version would advanced from the current version it is now - v9.2.0 for the DLPC3478 controller / DLP3010EVM-LC.

    Could you share what is included in the batchfile?

    If you wanted to check you weren't missing anything you could utilize the GUI for the DLP3010EVM-LC first and then implement all those commands to a batchfile. You can track the commands through the 'Debug' -> 'Command Log'.

    Here's an example:

    Setting to External Pattern Mode: (as an example)

    Now I can implement those commands into my batchfile (read commands are optional).

    This will also show you if your pattern configuration is able to be implemented.

    # 0x96 - Pattern Configuration
    W 36 96 00 01 01 00 01 00 00 00 01 00 00 00 02 00 00

    (1-bit mono,1 Pattern, Red Illumination, Illumination time (us) 256, Pre-Illumination Dark Time (us) 256, and Post-Illumination Dark Time (us) 512)

    This is a valid timing. Are you also writing the Trigger Out Configurations?

    Best,

    If there is no HDMI signal it starts up in external pattern mode from the batch file. As soon as it recognizes an HDMI signal it switches to external video mode. The batch file works but the hdmi signal forces it back to external video mode. How can this be changed?

    Hello Tom,

    Sorry, for my clarity... you are saying that at initialization it starts up with the splash screen with red, green and blue shown, you run the batchfile and the image turns red as you implemented only the red LED, right?

    After batchfile is implemented all red, then you're saying it will go back to an RGB splash image? How long does this take? Is this instantly?

    Best,
