DLPC3433: Creating Custom Firmware

Part Number: DLPC3433
Other Parts Discussed in Thread: DLPA3000

Hello, 


How can I create a custom firmware file for the DLPC3433?

I would like to adjust some of the battery management settings, splash screens, and maybe some other settings as well. 

Is there a software tool used to create custom firmware for the DLPC3433?

Thanks so much, 

Chris

  • Chris,

    Thanks for your inquiry. Are you designing for a custom board or using firmware for an existing EVM? Do you have a list of the changes you are interested in making?

    Regards,

  • HI Philippe, 

    We have a custom board, using firmware supplied to us on the optical module (light engine) from the manufacturer. 

    I have the DLP composer. 

    I am wondering how to change the low battery voltage cutoff. 

    I saw the setting in the datasheet for the DLPA3000. I believe it's register 0x10.

    How can I adjust this setting using the DLP composer tool?

    Thank you, 

    Chris

  • Chris,

    You may want to inquire with the optical module vendor for asssistance with this particular issue. There are two standard firmware versions for the DLPA3000. One is configured for AC power and the other is configured for battery power (and optimized for battery usage). The optical module vendor should be able to provide you a firmware that is optimized for your use case.

    Best Regards,

    Philippe
