CRTOUCH can not work with 5-wire TP? Hi dears: I start work with CRTOUCH, and found some problem with CRTOCH and 5-wire TP. I use "Xtrinsic CRTouch Capacitive and Resistive Touch-Sensing Platform Evaluation Board" The 5-wire TP can work under mouse emulation tab. And I successed calibration. But when I change to Gestures tab and start test, it shows: "Multi-touch points NOT calibrated. Please calibrate first at the 'Calibration' tab." Pls take a look at the following image: The calibrationg is ok. But here, it show calibration is not ok. The data from IC looks ok. When I use a 4-wire TP, it will work, but 5-wire TP not. Anybody who met this problem before? Thanks a lot! Pressure Sensors Sensing Platforms Touch Sensors Re: CRTOUCH can not work with 5-wire TP? Dear Jose: Thanks for your explanation. Now I'm fully understand. Thank you & best regards! 2014-05-28 ldqmoon From: Jose Alberto Reyes Morales Date: 2014-05-27 23:32 To: Luo Deqiang Subject: Re: - CRTOUCH can not work with 5-wire TP? CRTOUCH can not work with 5-wire TP? reply from Jose Alberto Reyes Morales in Sensors - View the full discussion Hi Luo Deqiang Unfortunately, dual touch gesture recognition is only supported for 4-wire resistive touch and unfortunately there is no other solution that we can offer to work with gesture recognition dual-touch with 5-wire. Basically, this is not a technical issue, but it is the way the algorithm is implemented for the CRTOUCH, this algorithm consider the impedance distribution of a 4-wire screen (connections, signal polarization) and therefore, the impedance distribution are different for the 5-wire screen panels. So, unfortunately , it is not possible to detect double touch gesture detection with the 5-wire CRTOUCH, 5-wire CRTOUCH only support single touch detection.
