This article mainly introduces the JavaScript events in the touch screen. The example analyzes the types, principles, and related usage skills of the touch screen events. For more information, see the example in this article. Share it with you for your reference. The specific analysis is as follows: I.

This project has been in operation for four months. Two weeks to find the microcontroller internal ad touch screen information, two weeks to select both with USB and with AD appropriate microcontroller. Two weeks of testing and demonstration, draw a schematic diagram. Then make the PCB and debug the engineering code. The successful experiment function is only the first step. debugging the Flying Point and f

Mobile End touch screen sliding effect is actually picture carousel, on the PC page is very good to implement, binding click and MouseOver events to complete. But on the mobile device, to achieve this kind of carousel effect, need to use the core touch event. Handling Touch events can track every finger that slides on

The Touch Screen driver is not implemented using the input subsystem. In fact, it is not much different from the driver of a common character device. You only need to follow the touch screen steps. ① S3c2410_ts_init function, which is the entrance of the entire program. Implements various initialization functions. /*

Some time ago, the touch screen and the Optical Mouse responsible for the project were all input devices. After reading the materials and combining the project code, I made a summary, which basically came from my personal understanding and the Internet. After linux2.6, Linux abstracts the input device and abstracts the input subsystem, which is the middle layer driven by all I/O devices, provides a unified

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 capacitive screen is offset

Port tslib1.3 Tslib and MiniGUI links Test Note: Because I recently used a PDA to implement camera functions, while my Development Board, mini2440, has only one USB, and my camera is USB, And the mouse is useless. I can only use a touch pen, the Touch coordinates are very inaccurate. First, I thought of tslib used in QT. I looked for it online and found the MiniGUI + tslib
