Part Number: DLPDLCR2000EVM

When I connected Raspberry Pi 3B+ with EVM 2000, I can able to see the desktop, but the screen is flickering / glitch. I saw a related article about changing the GND pin from EVM to Rpi3 pin 6 (GND).

I don't understand which GND pin from EVM? Please provide the exact pin number. There are 5 GND pins in EVM P2 side.

  • Hello Gopinathan,

    The ground of the Pi should be connected to the ground of the EVM so the signals have a common ground. It doesn't matter which specific ground pin on the EVM is used as all of the grounds are electrically the same.

    Thanks,

    Kyle

    Thank you Kyle.

    Is ang other troubleshooting guide to solve the screen flickering issue ?

    This is annoying for me. Initially I tried with BeagleBond black, I felt the performance is not good, unable to play video or browser smoothly.

    Later I integrated with Pi 4B, but the display never turned ON, i2c detects on address 7 instead of 3.

    Again I tried with Pi3B+, now everything is Ok, except the flickering issue.

    Hello Gopinathan,

    Did you attach the grounds of the two units? Additionally, if a different address is detected it should be simply changeable by software.

    Thanks,
    Kyle
