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.

I've actually been toying with the idea of doing something like this for the ELO drivers for some time. Before I go charging off and reinventing the wheel, does anything simiklar to this exist already? Ideally, it should be sufficiently generic that any input device that uses absolute coordinates will be able to use it. Cheers! |- | | Frederick F.

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.

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). They may be not perfectly precise but they are good enough for the precision of a finger touch - since the fingers are much bigger than pixels, you can't touch a particular pixel anyway. For ELO the range is around from 300 to 3700 I don't remember the exact numbers, for Microtouch it's from 0 to 16K. The drivers have the defaults compiled into them which can be changed from XF86Config. The problem is that the ELO driver has (had?) it's defaults set to 0-16K as well, so without an explicit setting in the config file it does not work in any useful manner. -SB -Original Message- From: Sergey Babkin [mailto:[EMAIL PROTECTED] Sent: Saturday, May 21, 2005 2:52 AM To: devel@XFree86.Org Subject: Re: Touch Input Driver port 3.3.6 - 4.x Fred Gleason wrote: On Wednesday 18 May 2005 18:48, Quentin Olson wrote: I have the source for an old input driver that was written for XFree86 3.3.6 that I would like to use under 4.x (4.5).
