    Hi Tao,

    Are you referring to the DLPLCRD-GUI to use with DLPDLCR3010EVM? This GUI can only work with the Devasys or Cypress USB-I2C adapters, as used in the EVM. If possible please describe your intended application so that we can suggest the best possible option.

    Hi Azad

    Thanks for your replay. Currently, we have designed a driver board based on DLPC3438&DLPA3000+MSP430G2452 MCU to control the optical machine. 

    The image can be displayed normally, but the MSP430 cannot control the DLPC3438 to do something by I2C. so we want to use GUI to debug the driver board, and we don't have the cypress chip on the board and Devasys. 

    So do you have any suggestion to control this driver board by my windows PC. 

    thanks

    Hi Tao,

    Can you describe what issue you're facing with using the MSP430 to send I2C commands? Also, have you looked at the MSP430 sample reference code available here: www.ti.com/.../dlpdlcr3010evm-g2 ?

    Hi, Azad

    Do you have any information about Cypress USB-I2C? P/N or special requirement?

    thanks

    can I use CYUSBS236 EVM (CY7C65215 - INTERFACE EVALUATION BOARD) board to do this?

    Hi Tao,

    Yes, you should be able to use this since the DLPDLCR3010EVM-G2 uses the same USB-I2C bridge IC.

    Please look into the EVM schematics available here for more information: TIDA-01571

    Hi, Azad

    Currently, I tried to use GUI to connect the DPLC3438 by Cyusbs236 DVK board. I connected SBC0 to I2C port of DLPC3438, but I got an error message. I attached the error message and my DVK board setting. could you help to checked it and give me some suggestions.

    Hi Zhang,

    I have a couple of questions:

    1. How is the CyUSB board connected to the DLPC3435 Driver Board? Through J112?

    2. Which MSP430 is the host to the DLPC? What code is it running?

    Regards
