LVGL calibrate touch screen #14459

s-hadinger · 2022-01-15T22:10:45Z

Description:

Tasmota Application useful for Touch Screen calibration (resistive touchscreens only). This application guides you through simple steps and generates automatically the required settings in display.ini (the ':M' line).

Download here

First download DisplayCalibrate.tapp application and upload it in the file system, and restart.
Make sure you are in orientation DisplayRotate 0
In the console, type the command DisplayCalibrate

You will see the following screens. Click on all 4 crosses near corners.

Note: measures are taken every 50 ms and are averaged, and requires at least 3 measures (150ms).

If everything went well, you will see the following screen. After reboot, your touchscreen is ready and calibrate.

If the geometry is wrong, you will see the following screen and no change is done to display.ini

COOL

michael-bartmann · 2022-01-27T19:57:13Z

Yes, cool. The first app I ran on tasmota. Still it fails for me (AZ-Touch MOD). After running through all 4 screens and pressing the cross, the device reboots with flickering of a white screen screen and display.ini is not modified. When setting log level to 4, I still see some events like:
20:54:56.561 TS : touched x=24 y=19 (raw x=3680 y=528).

Please provide full logs of the calibration process

s-hadinger · 2022-01-27T20:04:29Z

And please provide also your display.ini file

I am not sure if this is really the end of what could be logged; maybe some trailing lines have been lost due to reboot and lack of sync with the web console. Unfortunately it is not trivial to use serial log on that device, because there is a power conflict with the USB connector when the device is running with its own supply.

s-hadinger · 2022-01-27T22:38:43Z

Ah too bad. The interesting part was lost just before reboot. The :M line should have been updated by the calibration process.

I may have an idea why it failed. I need to do more tests tomorrow

michael-bartmann · 2022-01-27T22:45:29Z

There is one circumstance to mention. In the few demo applications I have run so far, including the berry demo, the screen and colors locked "clean". But the white background of the calibration screen has some disturbance (dim black lines/patterns flickering a bit). I assume this is not related to the issue with calibration app, but you never know...

s-hadinger · 2022-01-29T11:46:15Z

I did some more tests and I can't reproduce.

I can't explain the flickering either, DisplayCalibrate does nothing fancy except setting a white background

michael-bartmann · 2022-01-29T12:45:37Z

I've not found docs about tapps yet. Are these just Berry scripts with their name mapped to a tasmota command? If so, maybe I could execute the calibration step by step over berry console to isolate where my device misbehaves.
