Embedded Linux and Embedded System Design Abstract

周立功easyarm2200平台第三章试验源码-Ligong easyarm2200 week test-source platform for Chapter III

this is sleep and time function, you can have a look. it is programming by c language, the gold of this program is achieve   1.how to use time functions to measure time 2. to understand program execution in a multi-task environment 3. to understand the concept of time drift

工业控制研华板卡VC编程实 --Programming examples for YanHua board.

本人编写的FPGA光电编码器输入模块,没有实验,但仿真基本实现,希望有参考价值.-FPGA optical encoder input module, there is no experimental, but simulation technology, hope to have reference value.

由AT89S51单片机控制检测输入/输出显示和电机调速，按键输入，数码管显示，电机PWM驱动-Principle of the use of electric heating electric therapeutic apparatus developed with single-chip timing control devices, multi-file power conditioning, the temperature of 30 ° ~ 90 ° between the adjustable

PLC 高级指令 包含有osr、osf,算术指令、移位指令等-Senior Command PLC contains osr, osf, arithmetic instructions, shift instructions, etc.

#定义启用位定义

仿真例程应ucgui3.9.0函数库包，函数库中实现了多窗口切换，滚动条的滚动实现界面滚动，利用自己写的局部重画方式，下载硬件后仍然比较流畅 

用于Linux下的触摸屏驱动，使用在2.6.15版本内核上，可以作为两种方式使用，运行可靠稳定。-For the Linux driver under the touch screen, use the version in the 2.6.15 kernel, it can be used as two ways, reliable operation and stability.

本代码是基于PXA270开发板的I2C总线驱动程序-This code is based on PXA270 development board I2C bus driver
