BBView 7 : can't calibrate / Angstrom

PaulRowntree

Hi!  I have got my BBB and BBView7 to work together, but the touchscreen won't calibrate.  It goes through the first two markers, but claims a 'mis-click' on the third, and restarts the process.  Tried fingers, stylus, etc, no difference.  The screen seems to register contacts everywhere (always finds the mis-click) but can't get through the process.

As a result, there is no /etc/pointercal file, ever.

I get a decent screen view, the LED's work, it is just the touchscreen that seems incorrect.

 

Could someone please post their /etc/pointercal file(s), and I will see if that makes it fly?

Thanks!

    The fix : from an ssh connection I ran ts_calibrate, which is a different program from the default one that runs.  It used a few points, generated the /etc/pointercal file.  That file is ascii, single line, last two values are screen size

     

    root@beaglebone:~# more /etc/pointercal

    -19 -13767 54979872 8599 103 -2428058 65536 800 480

     

    restarted BBB, and it tried to do the std calibration program.  Waited it out without touching the screen, then it booted to gnome shell, and all is well.
