Hi, thanks for providing these links.
I'm trying to get my 7" Waveshare screen working in the same way.
I'm following the instructions, and when I run the calibrate command I
get the following thing happen:
Code:
--------------------
sudo TSLIB_FBDEVICE=/dev/fb0 TSLIB_TSDEVICE=/dev/input/event0
/usr/local/bin/ts_calibrate
xres = 1024, yres = 600
Took 1 samples...
Top left : X = 15 Y = 21
Took 1 samples...
Top right : X = 15 Y = 21
Took 1 samples...
Bot right : X = 15 Y = 21
Took 1 samples...
Bot left : X = 15 Y = 21
Took 1 samples...
Center : X = 15 Y = 21
ts_calibrate: determinant is too small -- 0.000000
Calibration failed.
--------------------
It stops after I press the crosshair in the top left.
The odd thing is this screen works perfectly in Raspbian without any
calibration, touchscreen is very accurate.
Is there a way to use to the settings/calibration from Raspbian in PCP
for using Jivelite?
