    Prabhuram,

    You do not need an MSP430 or its code to do anything with your HDMI to DPI setup. Rather, the reason this was mentioned was because the MSP430 is used in the DLP2010EVM in order to automate the process of programming the DLPC3430 to external video mode. This was useful for a setup with the ITE6801.

    If you understand the I2C commands required to set the DLPC2607 to external video mode at the correct resolution, as well as the commands required to set up your HDMI to DPI chip, then you do not necessarily need to use the same MSP430 implementation.

    I hope this helps. Let me know if you have additional questions.

    Regards,

    Philippe Dollo

    Prabhuram,

    The command for video source selection is in section 2.4.1.3 of the Software Programmer's Guide. You also need to set the video resolution using the resolution command in section 2.4.1.6.

    As for the HDMI receiver chip, I recommend you pull these from the MSP430 code available on TI.com for our other EVMs. I'll link you to one such example:

    I hope this helps.
