RE: Live Touchscreen Calibration [WAS: magictouch touch screen driver]
Hi, actually a great thing to have, but not that easy. The main problem is, that the driver itself has to be disabled. - this can be solved by quitting X and doing a calibration with touchcal - the other possibility is (I don't know how) to disable the driver while running X and then doing the calibration. and finally enable the driver again Maybe this is not possible. There is no function to disable a pointer device while running X. So you could add a feedback function to gain access to the driver and have a enable/disable routine.

Sergey, but anyway if your touchscreen is mounted in the wrong way the pointer will then not follow your fingertips this is from xf86Elo.c < /* *** * * Default constants. * *** */ #define ELO_MAX_TRIALS 3 /* Number of timeouts waiting for a */ /* pending reply. */ #define ELO_MAX_WAIT10 /* Max wait time for a reply (microsec) */ #define ELO_UNTOUCH_DELAY 5 /* 100 ms */ #define ELO_REPORT_DELAY1 /* 40 ms or 25 motion reports/s */ #define ELO_LINK_SPEED B9600 /* 9600 Bauds */ #define ELO_PORT"/dev/ttyS1" #define DEFAULT_MAX_X 3000 #define DEFAULT_MIN_X 600 #define DEFAULT_MAX_Y 3000 #define DEFAULT_MIN_Y 600 > > -Original Message- > From: Sergey Babkin [mailto:[EMAIL PROTECTED] > Sent: Wednesday, May 25, 2005 2:16 PM > To: Veikko Werner; [EMAIL PROTECTED]; devel@XFree86.Org > Subject: Re: RE: Touch Input Driver port 3.3.6 -> 4.x > > > >From: Veikko Werner <[EMAIL PROTECTED]> > > > > >There are no default Xmin/Max Ymin/Max values for any > resistive touch devices. > >A good possibility would be to include a calibration routine > into the driver if possible. > > There are manufacturer-specified ranges for both > ELO and Microtouch (though I don't know if they > are using the resistive technology).

RE: Touch Input Driver port 3.3.6 -> 4.x
There are no default Xmin/Max Ymin/Max values for any resistive touch devices. A good possibility would be to include a calibration routine into the driver if possible.
