I haven't worked with touch screens for a while, but generally the protocols are inanely simple. Something along the lines of 4 quartets: X, Y, Pressure, <something else>
Ack.. it has been a little too long. Anyways, the hardest part of the whole exercise is to get the calibration and jitter control working. The actual input of the data itself is pretty trivial. The other two can probably be ripped off someone else's drives. I used the touch screen drivers in Kdrive, so that may be a place for you to start looking for working examples. -----Original Message----- From: Bodo Bimboese [mailto:[EMAIL PROTECTED] Sent: Friday, September 12, 2003 4:49 AM To: [EMAIL PROTECTED] Subject: Touchscreen input driver Hello All, Please apologize if this request is wrongly placed. I'm not familiar with programming, just a keen user. I'd be thankful, if anybody could point me into the right direction. I'm using X (4.3.0) on Linux, and I'm struggling to get a touchscreen (-input) device to work. It's not one of those popular manufacturers whose driver is included with 4.3.0 Things I've found out yet: manufacturer of the 12" TFT monitor with touchscreen is a no-name Asia-based. The interface is RS-232 with 9-pin serial connector and a PS/2 dongle-style plug (the mouse plugs into the back of this plug). Touchpanel manufacturer is a company called Hantouch Serial driver PCB manufacturer is a company called Sena (both companies offer downloads, but I didn't found any for X) The monitor is marketed under the label Glancetron in Europe (They only offer Win drivers unfortunately) Since I haven't found any *nix drivers on the net, I've tested all input drivers which came with X. None of the touchscreen drivers work, some cause X to abort. The only reaction I get is from the DigitalEdge tablet driver, which causes a 'click' in the bottom right corner of the screen, no matter on which area I touch it. My question is: Would it be an easy task to modify an existing driver to get the touch element to work? I've had a look at the Elotouch driver sources, and it doesn't look huge. I have no idea about programming, but I'm motivated to take the challenge. cheers, Bodo ________________________________________________________________________ ______ 38xTestsieger - WEB.DE FreeMail - Deutschlands beste E-Mail Design-Mails - einfach schoenere E-Mails - http://f.web.de/?mc=021129 _______________________________________________ Devel mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/devel _______________________________________________ Devel mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/devel
