DLP2010EVM-LC: I2C commands without using gui

Part Number: DLP2010EVM-LC

Hey,

I would like to stream 40 patterns. Using GUI, internal patterns, I successfully projected. But is it possible to project them without connecting to GUI through USB and using trigger_in i.e 5th pin of J4 on display board. Also I would like to control the trigger to each pattern of my stream as I require them to sync with my camera capturing time. I have tried but the moment I disconnect the USB , only the default images can be projected. Please guide. I am working on structured light scanning method using DLP2010EVM-LC pico series. DLPC3470 is the pico processor on evm

Thank you

  • Hello Shravani,

    You should be able to configure the EVM using the GUI and then control the patterns using the external trigger. However, if you power off the device then reboot it you will again need to configure the EVM using the appropriate commands (either via USB over the GUI or I2C commands). You will not need to re-upload the patterns this time as they are already uploaded. You will just need to ensure the EVM is in the appropriate input mode.

    Thanks,
    Kyle

    Thanks for the response, Kyle
    Can you describe me all possible ways of giving i2c commands in this kit, if possible in brief?
    Thank you

    Hello Shravani,

    The easiest way will be for you to send the commands via the GUI then select "Debug" mode and view the command log. You can even export your I2C commands to a batch file for reuse. The official documentation for I2C commands can be found at www.ti.com/.../getliterature.tsp . J14 is a header that can help you achieve direct access to the I2C bus.

    Thanks,
    Kyle
