HMI not working with RPi+touchscreen

  • I have some troubles running HMI on RPi with touchscreen. Visualization works perfectly when connected to RPi via PC with Chrome or IE. If chromium is run via touchscreen connected to RPi, visualization is dead and stuck. Tried fresh installation of 2.50.9. Tested on 2 different devices with the same result. Either my own examples nor the official examples do not work on RPi with touchscreen. But it used to work perfectly in older version. Thx for help. Steven.

  • Hi Stepan,

    I'm sorry to hear that you struggle using HMI. I just tried to reproduce the error without success and did following:

    • Install Raspbian Stretch with desktop
    • Install REXYGEN (Getting Started)
    • Start from an Example Project -> 0120-01 Getting started
    • Compile and Download
    • Open Chromium on Touchscreen and navigate to

    Please, can you try to go through and report results?

    Thank you for cooperation.

    Regards, Tomas

  • Thanx for guidance. I followed the instruction successfully. The only explanation I can think of is that I used older Raspbian (2017). If the latest Raspbian is used, everything works fine.

  • Thank you for update. If you encounter any strange behaviour again, please, let us know.
    Good luck with your project!

    Cheers, Tomas
