MHS-3.5inch Display! Touch Screen does not work

Help and Support Help

I would not recommend to run the script from goodtft’s GitHub repository. Instead try the following:

  1. Start with a fresh Volumio system.

  2. Install the Touch Display plugin from Volumio’s plugin store: Click on the “burger” sign displayed in the left upper corner of Volumio’s UI then choose “Plugins”. On the tab “Search Plugins” choose “User Interface”. From there install the Touch Display plugin.

  3. Execute

sudo apt-get -y install xserver-xorg-video-fbturbo

sudo apt-get -y install xserver-xorg-input-evdev

sudo cp /usr/share/X11/xorg.conf.d/10-evdev.conf /usr/share/X11/xorg.conf.d/45-evdev.conf

sudo curl -L https://github.com/goodtft/LCD-show/raw/master/usr/mhs35-overlay.dtb -o /boot/overlays/mhs35.dtbo

sudo curl -L https://raw.githubusercontent.com/goodtft/LCD-show/master/usr/99-calibration.conf-mhs35-90 -o /etc/X11/xorg.conf.d/99-calibration.conf

sudo curl -L https://raw.githubusercontent.com/goodtft/LCD-show/master/usr/99-fbturbo.conf -o /usr/share/X11/xorg.conf.d/99-fbturbo.conf

cat >> /boot/userconfig.txt <<EOL

dtparam=spi=on
dtoverlay=mhs35:rotate=90
EOL
  1. Reboot.

BTW: What is your Volumio version?
