[TUTO] touchscreen rotations

I had tried setting that but failed (see my above initial question). So the answer is: no, I don’t have that.

Now the good news: I meanwhile managed to change the touch rotation. I had not paid enough attention to the Waveshare wiki for this display. In fact, that wiki even clearly states that the touch rotation is not automatically following the display rotation. And, it also explains how to adapt the touch rotation :slight_smile:

here the steps necessary:

sudo apt-get install xserver-xorg-input-libinput
sudo mkdir /etc/X11/xorg.conf.d
sudo cp /usr/share/X11/xorg.conf.d/40-libinput.conf /etc/X11/xorg.conf.d/
sudo nano /etc/X11/xorg.conf.d/40-libinput.conf

in this file, find the touchscreen section, and add one of the commands below depending on the rotation wanted:
90-degree rotation: Option “CalibrationMatrix” “0 1 0 -1 0 1 0 0 1”
180-degree rotation: Option “CalibrationMatrix” “-1 0 1 0 -1 1 0 0 1”
270-degree rotation: Option “CalibrationMatrix” “0 -1 1 1 0 0 0 0 1”

reboot, and you are all set!

so, all good now, and I have both the standard display and the Now Playing widget up and running.

Really cool stuff, love it, and much appreciate the work of all involved! In essence, after investing an old Raspberry 4 I had laying on my desk, €50 for a DAC hat, and @100 for the display, plus maybe 2 hours of my time, I now have a music server that really rocks, with great audio quality (connected to my high end audio system), and a really cool UX (that even my wife already uses :slight_smile:)

Now I have 3 questions left, that maybe someone can also answer?

  1. right now I use the HifiBerry DAC2 Pro, and it works just fine (even though it is not directly available in Volumio, but I had to select the older HiFiBerry DAC+ Pro instead). Now I am wondering whether there is any better DACs available that would further improve audio quality, like the HiFiBerry DAC2 HD or something like the AUDIOPHONICS DAC I-Sabre ES9038Q2M?

  2. currently I am on the free version of Volumio, but certainly will upgrade once my test project here is finished successfully. What I have not yet set up is streaming services like Spotify or Amazon Music HD. Is that available with the full version of Volumio only?

  3. I am looking for some nice housing for this system, that kind of fits to my HiFi set. Any idea where to get something like this from?
