Hi, i did a few changes and i successfully compiled it, but when i try to calibrate the touchscreen i get the next:
shell@android:~# ts_calibrate xres = 1280, yres = 720 Took 41 samples… Top left : X = 0 Y = 0 Took 27 samples… Top right : X = 0 Y = 0 Took 16 samples… Bot right : X = 0 Y = 0 Took 22 samples… Bot left : X = 0 Y = 0 Took 10 samples… Center : X = 0 Y = 0 ts_calibrate: determinant is too small — 0.000000 Calibration failed. the touchscreen is an eGalax, i patched the tslib code with a patch for eGalax, but i don't know what could it be, i keep getting that result with the calibration, any ideas about why?, thanks in advanced.
