Assuming the RPI Touchscreen is the Raspberry Pi Touch screen
I went to the help center, but this to me doesn’t make sense. Any additional input would be appreciated. Was I supposed to install the plug in before connecting the touch screen?
If the screen does not show properly the Volumio’s user interface probably you did not install the TOUCH DISPLAY plugin, downloading it from PLUGIN section of the Volumio UI
So, first, access to Volumio, via APP or volumio.local web browser’s address
Download the plugin
Connect RPI touchscreen
After I installed all of my components, I.E. screen, hat, etc. I installed the micro Sd card, waited for the boot to show a QR code and provide a IP address where I accessed the GUI or UI (I am not sure on what is the proper term), then installed plug in. Which is when I receive the error.
