CCS/DLPDLCR4710EVM-G2: Autobrightness w/ Raspberry Pi & OPT3001

Part Number: DLPDLCR4710EVM-G2
Other Parts Discussed in Thread: OPT3001, DLPC3439

Tool/software: Code Composer Studio

I'm trying to implement an AutoBrightness feature using an OPT3001 and a Raspberry Pi. At the moment my first thought is to use the i2c communicate between the 3 devices with the Raspberry Pi as the master. Am I on the right track or is there something I'm not considering?

    Lucas,

    Welcome to the forums and thanks for your interest in our DLP products.


    Yes, you can make brightness adjustments on the DLPDLCR4710EVM using I2C commands. In particular, I recommend checking Section 2.3.3.48 in the DLPC3439 Programmer's guide for more information on LED current I2C commands to use:

    I hope this helps.

    Best Regards,
