I tried to build a touchscreen music player out of a PI3, Volumio 2.185 and a odroid 7" touchscreen.
The touchscreen plugin installation worked fine and it boots right into the UI.
Unfortunately i encountered a few problems.
The touch function does not work.
I only see the UI with a pointer in the middle of the screen. No matter where i press on the screen it does not react.
Connecting a mouse i can move the pointer and use the UI. So it seems it has something to do with the touchfunction.
The UI is only displayed on the left 3/4s of the screen. The remaining 1/4 remains un-used.
on the leftmost side there is a small pink stripe 2 pixels wide from top to bottom.
i sorted out the screen size problem by adding the right resolution (800x480) to the config.txt
unfortunately the non working touch function still is not solved. Any ideas ?
( i tried adding max_usb_current=1 to the config.txt but that did not work)
I believe that the “Yellow Flash” symbol on the screen is a warning of low power - I wonder if this could be the cause of your issues?
My very limited experience of Linux is that its not really “Plug n Play” you need to be a full up computer geek to get it going - so good luck.
BTW I also ordered the same screen (with Capacitive touch version) - which version do you have Resistive or Capacitive touch (it looks like a Capacitative touch type)?
Once the Panel arrives I’ll give it to Jarek who works with me and I’m sure we will get it going…
