Forum Post: RE: ts_test varying results after reboots

$

Hi Miroslav,

Thanks for your reply.  I was playing around with ts_print* the other day, but wasn't sure what to make of the results.  I'm not sure if I'm taking the best approach to using ts_print.  But below are results from this morning.  

I did a clean boot, no power applied for at least 1 minute.  Run ts_calibrate, run ts_test to confirm calibration.   Then I rerun ts_test and control c to quit, just to repaint the cross hairs in the center of the screen.  Then i run ts_print_raw and use a wooden pointer to hit the center as close as possible.  I've tested rebooting by typing reboot at the console and also disconnecting power, I've found no correlation to this.

Below are three adjacent samples from ts_print_raw, hitting the same(or as close as possible) location at the center of the screen, after a fresh boot.  After first boot calibration, the calibration was off may reboots, then it was right on three reboots in a row, and then off again.  Its very odd.

Thank you.  Any suggestions or guidance is greatly appreciated.
