It should be noted that the display through the USB connection to the PC, will affect the transmission rate to some extent, in our test, the mobile hard drive through the USB 2.0 directly connected to the PC transmission rate of 20Mbps, connected to the monitor is down to 13Mb

Secrets of Embedded Linux/Android driver development (1) Touch
The ADCTSC registers are shared between the ADC Driver and the touch-screen driver. How can one register be used when processing them? -- Linux general technology-Linux programming and kernel information. The following is a detailed description. You guys give me directions
I wrote an ADC digital-to-analog conversion
Summary: This article mainly introduces the design of the touch screen Driver Based on QT/embeded in the embedded Linux system, and introduces the working principle and mechanism of the driver interface of the Linux device and the QT/embedded device, combined with a large amount of source code for analysis, the develop
This document describes how to develop an I2C interface touch screen driver mounted on the friendly mini-2440 platform.
Kernel edition linux-2.6.32.2,The platform is a touch screen with the arm9-s3c2440 + I2C interface.
For exampleLinux I2C
Design of I2C-based embedded multi-point touch screen driver
Abstract: With Samsung's 7958 processor, the driver Management System of Embedded Linux is used to implement the design of multi-point touch screen
Abstract: The Linux operating system is highly open and portable. It is widely used in embedded operating systems. This article first builds the hardware environment based on Samsung's S3C2410 processor, and then explores the touch screen driver in the embedded Linux operating system.

Touch screen driver SamplesSample Code for touch screen drivers is provided in the following directories:
% _ Winceroot %/platform/xsc1bd/Drivers/touchp

Recently to customers debugging a piece of CNC board, today customers bring a screen, and a USB touch screen chip connected to the screen. The screen will soon be ready for normal display.

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

Several of the previous articles have been ported by configuring DTS for multiple drives, and then we are addressing tq335x's touch-driven issues. For various reasons, tq335x touch screen drive is provided by the module, and the Linux official kernel also does not have the drive source code with the touchscreen, the simple configuration of DTS is unable to comple
Then probably introduced after the monitoring event, then the touch screen of the most concerned should be more contact;

I. One of the prerequisites for writing a touch screen DRIVER: Input subsystem
1. Introduction to the input subsystem
The input subsystem is provided in Linux. input devices, such as buttons, touch screens, and mouse, can use input interface functions to drive devices.
2. Composition of the input subsystem

Statement in advance: The article only records the porting process for your convenience.
The touch screen of the mini2440 Development Board is the NEC touch screen, while the Android kernel provided on the FriendlyArm is for the tongbao LCD. Therefore, you need to modify the touch
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
