I installed the screen using instructions located on https://www.waveshare.com/wiki/3.2inch_RPi_LCD_(B) using the tar.gz install file
The screen works with touch registering but my touches but my axis are inverted. Moving my finger Left goes up; moving my finger R moves down. Moving my finger Down goes L; moving my finger Up goes R
I googled around and this seems to be a common problem. Using the command below my x axis works as intended by my y axis is still inverted.
Code: Select all
xinput set-prop 'ADS7846 Touchscreen' 'Coordinate Transformation Matrix' 0 1 0 1 0 0 0 0 1
I played around with other values in the http://www.calcul.com/show/calculator/m ... iplication and 0 -1 0 1 0 0 0 0 1 seems to give me the correct transformation but my cursor is then just stuck to the left side of the screen.
Can anyone help with the proper transformation?
