6 years ago I don't know what the interaction is between the Kivy libraries (this is what is used for the touch-screen UI) and your screen drivers. So I can't help directly. However, if you want to take a vanilla image and install all the pre-requisites for Pi Scan yourself, you can do the following:
-
Set up locale/keyboard stuff (unless you want to leave it as Great Britain keyboard locale)
-
Install these apt-get packages:
python-setuptools python-dev pkg-config python-pip build-essential python-pil git-core dbus python-dbus udisks2 exfat-fuse liblua5.2-0 lua5.2 liblua5.2-dev libusb-dev build-essential libltdl-dev libusb-dev libexif-dev libpopt-dev libudev-dev pkg-config git automake autoconf autopoint gettext libtool wget
-
Install gphoto2 (for latest version, install here instead of from apt-get https://github.com/gonzalo/gphoto2-updater )
-
pip install -I Cython==0.25.2 -
pip install lupa --install-option="--no-luajit"
ldconfig
udev_version=$(udevd --version)
if [ "$udev_version" -ge "201" ] then udev_rules=201 elif [ "$udev_version" -ge "175" ] then udev_rules=175 elif [ "$udev_version" -ge "136" ] then udev_rules=136 else udev_rules=0.98 fi
-
Install wiringpi
-
Install Kivy dependencies:
libsdl2-dev libsdl2-image-dev libsdl2-mixer-dev libsdl2-ttf-dev libgl1-mesa-dev libgles2-mesa-dev libgstreamer1.0-dev gstreamer1.0-plugins-bad gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-ugly gstreamer1.0-omx gstreamer1.0-alsa libmtdev1 libmtdev-dev xclip
- Install Kivy
apt_file="/etc/apt/sources.list.d/mitako.list" apt_entry="deb http://archive.mitako.eu/ jessie main" apt_key="http://archive.mitako.eu/archive-mitako.gpg.key" apt_cache="/var/lib/apt/lists/archive.mitako.eu_dists_jessie_main_binary-armhf_Packages"
echo "Registering pipaOS repository: $apt_entry" echo "$apt_entry" | sudo tee $apt_file > /dev/null
echo "Adding repository key $apt_key" curl -L "$apt_key" | sudo apt-key add -
echo "Refreshing available packages" apt-get update
apt-get install python2-kivypie
- Install configuration files. See attached.
Now you should be able to play around with the kivy options in .kivy/config.ini (default options are at: https://github.com/Tenrec-Builders/pi-scan/blob/master/config/touch.ini ). The read-only stuff isn't installed either so you don't need to muck around with remounting to modify stuff. But you do need to remember to shutdown cleanly. Once you have figured out the driver/kivy issues, please post here and I may integrate those options back into the main code base.
Best of luck.

I don't know whether this is the right place to ask this but I'm having some trouble with this touch screen (https://www.amazon.co.uk/gp/product/B075JFT9SF) which I want to use with my Raspberry Pi 2 and pi-scan. The touch screen works fine with a normal raspian installation and is calibrated very well however does not work at all with the 'touch screen' version you supplied (I understand this is for the raspberry pi touch screen only) or the mouse version. I have removed the read only permission from the / and /boot mounts and installed the drivers for the screen (https://github.com/goodtft/LCD-show) and the screen resolution is now fine but the touch screen is 90 degrees out - when I press the top right, it shows in the bottom right and when I press on the bottom right it shows in the bottom left etc. I realise this is a very specific issue but could you help at all?
