AR1100 installed on RaspberryPI 3B X-axis inverted

Post by AGUZMAN76 »

Hello There!
I've installed an AR1100 touchscreen board (connected to a 12" resistive touchscreen) to my RaspberryPI 3 B.
The PI is running raspbianOS.
I installed the raspberryPI the software "X11" driver which has it's own calibration software.
("Calibration standard Xorg driver "microchip technlogy inc. AR1100 HID-MOUSE".
The calibration program runs fine and the 4 calibration points appear on the screen and it "seems" to calibrate fine.
HOWEVER, the X-axis is inverted. Y-axis calibrated just fine.

I've followed instructions to adjust the "99-Calibration.conf" file, but this doesn't do anything to the X-Axis.
Please see a couple of attached pictures.
Note that I've edited files in the folders:
/usr/share/X11
and
/etc/X11
editing in either location makes no difference, the X-axis is still inverted.
editing the 99-calibration.conf file.

Are you using xinput_calibrate or a different utility?

There is also a rpi-AR1100 github repo that has a Raspberry Pi utility that is being maintained. This is the one recommended in the Adafruit Guide to try.

Mikeysklar, Thanks for your reply!

I'm using the xinput_calibrate utility.

I'll try the github link you mentioned and see how that goes.
