it makes you suffer... I was an icdesign company, but now I want to take over the mess of a mobile phone solution. We will go public in two months, saying that we will not be able to solve some problems. Last week, I gave us information to make a capacitive screen. When I get my cell phone, I can't help it! The whole screen-tip of the

Based on "optimization of four-wire resistive touch screen drive", the sensitivity parameters of handwritten input are adjusted too low, which is better than the original one, as shown in, 72/s can be achieved now. Generally, the writing speed is about 60/s, so it should be able to meet the vast majority of requirements. The CPU usage is slightly higher than t

This address, reproduced please specify: http://blog.csdn.net/dearsq/article/details/51251009How Hardware WorksThe working principle of the touchscreen is to report the values of coordinate values, x-axis and y-axis. So the input subsystem is used in Linux to implement it.Specific hardware principles can refer to this article capacitive touch-screen hardware fund
