'Resistive Touch Display 7" Parallel' vertical axis inverted on Colibri iMx6ULL?

[embeddedEd]

I purchased two 7 inch displays from the Toradex website:

• 7.0” WVGA 800 x 3 (RGB) x 480 High Brightness Resistive Touch TFT Module
  for the use with Toradex Apalis and
  Colibri modules.

When using the Toradex Qt E-Bike Demo image, all is good except the vertical axis is inverted. See attached image:

The page Touch Calibration section on Resistive Touch Screen (Linux) says:

“BSP 2.x automatically performs a calibration”.

The calibration looks pretty good except it is inverted on the vertical axis.

Any tips or suggestions on how to fix?

Thanks in advance,

-Ed

Did you actually calibrate your touch screen? A resistive touch screen will always require manual calibration and as such that should also automatically take care of whatever axis may need inverting or not.

By “BSP 2.x automatically performs a calibration” we mean that such BSP did automatically launch such manual calibration upon first boot. Whether or not any 3rd party Qt image will do so I can not comment.
