I have a Pimoroni Hyperpixel 4.0 touchscreen display, attached to a Rpi 3B+. I can get the display working using the process below, but I can’t get the touchscreen to work and I don’t know where to start the troubleshooting process. Any help would be much appreciated!
Below is my third revision of the process and all items now install without reporting any errors:
1. Install Volumio 2.713 and Touch Display 1.1.6 Plugin 2. sudo apt install apt-utils 3. sudo apt install device-tree-compiler 4. sudo apt-get install rpi.gpio 5. sudo git clone [github.com/pimoroni/hyperpixel4](https://github.com/pimoroni/hyperpixel4) -b pi3 6. cd hyperpixel4 7. sudo ./install.sh
The Volumio interface is displayed and looks great (IPS panel 235 PPI @60FPS), I just wish the touchscreen capability was working. BTW, the unit interfaces entirely via GPIO, with no USB or hdmi connections. “sudo i2cdetect -7 3” shows the touchscreen is using i2c address 0x5d, and /dev/i2c-3 is present. I’ve just no idea how to point to it and use it.
Again, any advice on where to start the troubleshooting process would be much appreciated.
