    Hi Frank,

    Yes, I2C configuration supports for commands mentioned in Programmer guide of DLPC3433.

    Flash contains the firmware of DLPC3433 and it is connected over SPI.

    Thanks,

    Hello Frank,

    Firmware is available here : www.ti.com/.../DLPDLCR3010EVM-G2
    Yes you can modify the few options in firmware using EVM GUI tool. Available at the same page : www.ti.com/.../DLPDLCR3010EVM-G2.

    Please refer the Programmer guide for DLPC3433 IIC commnad description. www.ti.com/.../dlpu020c.pdf

    Dear Navneet

    At present, the client is facing such a problem and is in urgent need of your support.

    Abnormal Screen phenomenon description:
    1. There are 6 main boards tested, and the results are quite different. With the increase of temperature, some on the left and some on the right of the optical machine display（There are two DLPC3433 on each side ）.Sensitivity to temperature is not uniform, and some are good.
    2. We have check the peripheral circuit of DLPC3433，there are no exceptions.
    3. We have used the flash with the DLPC3433 firmware on a good mainboard to exchange the flash of a abnormal dlpc3433. It seems there's nothing to do with the firmware of dlpc3433.
    4. We have adjust the host mipi clk(from -10% to +10%).There is no good.

    So is there any registers that can help us analyze this problem?
    Or anything else we have to check?

    Hi Frank,

    What issue you are seeing with increase in temperature ? 

    When you are saying increase in temperature, it is DLPC3433 chip only or the optical engine.

    Are you using proper way of cooling the optical engine ? Who provided you the optical engine, please discuss with them for cooling the optical engine.

    You mentioned you are using two DLPC3433 in your application, could you please elaborate your application.

    Thanks,

    Navneet

    Dear Navneet


    What issue you are seeing with increase in temperature ?
    ---My real question is that some chips are good and some chips are abnormal with the same optical machine.

    When you are saying increase in temperature, it is DLPC3433 chip only or the optical engine.
    ---We have tried to cool down the optical machine or DLPC alone.The phenomenon is of no use to optical cooling.But when we continue to cool down the DLPC, so that abnormal phenomena will not occur

    Are you using proper way of cooling the optical engine ? Who provided you the optical engine, please discuss with them for cooling the optical engine.

    ----At present, the ratio is poor, not every poor, may I ask whether it is related to the optical module?

    You mentioned you are using two DLPC3433 in your application, could you please elaborate your application.
    ---One for the left optical machine and one for the right optical machine, the device is a AR glass like microsoft hololens

    Hi Frank,

    What do you mean by abnormal, can you please elaborate. Chips mean DLPC3433, right ?

    Yes, cooling is required. Optical module should provide the proper cooling for DLPC3433 as well as illumination part. Discuss with optical manufacture.

    Thanks,

    Navneet
