calibrate ipod touch screen

developer, can use to sample and calibrate the screen with the touch screen DRIVER: Call the touchpanelenable function to start the screen sampling. Call the touchpanelgetdevicecaps function to request the number of sampling points. For every calibration point, perform

A general formulation: JS Code $ ("#u_obj_id"). Bind (' Touchstart ', function (e) {point = Hastouch? E.originalevent.touches[0]: E; Point represents the touch screen //Some action }) This allows the JS code to support the touch-screen events of the mobile device. If the effect is more demanding, you can use Jquery-mo

The Touch Screen driver reads user input from hardware and then converts it into a touch event and sends it to GWES. at the same time, convert the coordinates of the calculated coordinates to the calibrated coordinates. calibration coordinates compensate for hardware exceptions, such as touch Skew and non-linear order.

Recently updated sam9263 Angstrom, resulting in a poor touch screen, the performance of the touch is not allowed. Of course, there is a touch calibration when starting. Google, as if the latest x is the use of xorg, can not directly support tslib, to use x xf86-input-tslib driver, using openembedded compiled the driver

). It is as simple as doing it. In this way, the invalid coordinate points before being lifted are removed directly because the sampling time of an ad is delayed: If (not the lift action) { Send the last coordinate via USB } Else { Send lift action } It is not easy to make a real product. This project is used for the same batch of touch screens. In a non-touch state, the voltage value sampled by the ad ha
