Hi I have a question: I got everything running, thanks to the many tips here. The longest task was the touch screen mirrored on the x axis which I corrected the
99-calibration.conf file:
The only problem I have and I do not find the config file. I would also like to control the “Browse library” by the touchscreen but I can’t. I can control everything through the browser but when I am in “Stand alone” mode, I would like also to be able to choose the music… How can I do this ???
Do I need to buy a bigger tft ?
What config file do you mean? The files named “config.txt” and “userconfig.txt” both reside in “/boot”.
The local display should show the same UI like in a browser on another device. It could be that the mobile version of th UI is shown if you are using your touch screen in portait mode but you should be able to reach “Browse library” nonetheless.
If you should be using the “contemporary” UI theme you could try the “classic” theme which might fit a small screen better.
It modifies /boot/cmdline.txt and renders Volumio unbootable. It is possible to “repair” that but typically it is faster / easier to just start with a fresh Volumio system. Then don’t run LCD-Show but do the necessary steps manually. What is necessary depends on your screen.
What is the brand and exact model name of your screen?
I caught the crash pretty early on boot still on the HDMI. The crash stack implies that I’m missing some register here which leads me to the conclusion that this is some weird controller sitting on the GPIO.
As far as I can see I may do it in 2 ways:
the annoying trial and error:
Flash volumio, test driver, see what it does
find some clue about the controller and debug into it, maybe write my own driver.
depending on how far me this bottle of wine gets today, I may end up with the 2nd option.
IMHO there is no need to write a new driver. If you could identify your screen most probably you can get along without that. Is it touchscreen or just an HDMI connected display?
