Touch axes inverted #390

Open MihirGrand opened 2 months ago

MihirGrand commented 2 months ago

Hello again!

I am able to see my app well on the display, its a 3.5" touch display

I am also able to click buttons in my app, but the calibration is way off. I tried adding a single button to the entire screen and tapping to see where I touch and where it actually gets tapped.

I'm assuming I have a similar problem to those mentioned in some previous issues where the calibration was off

I tried building your calibrator at https://github.com/ardera/flutter_libinput_calibrator using flutter-pi with the usual steps but I get the following error -

Building Flutter-Pi bundle...
Failed to build bundle.

How do I proceed from here? If not to use this tool, how do I manually debug and calibrate the display?

MihirGrand commented 2 months ago

So I copied the code from your libinput calibrator, pasted it in a new project, and it built successfully without google fonts. I ran it on my raspberrypi but there's one issue, the app goes out of bounds of the display horizontally, it extends beyond so some part is cut and I can't access the targets on the right. How do I fix the resolution issue? I already set the framebuffer width to 480 and framebuffer height to 320 in /boot/config.txt
