MODBUS代码，希望对各位有所帮助，共同进步-MODBUS code you want to help each other circulated in order to have progress

AT91RM9200的USB host和USB device的代码ADS1.2. USB-Device测试程序: 因为程序运行在SDRAM中，所以要先初始化SDRAM（可用basic boot程序初始，之后不能复位或断电），再运行此程序，程序运行后连接USB端口，计算机会提示检测到新硬件，安装硬件驱动程序atmusb6119.inf 后计算机会把USB端口虚拟为一个串行的端口使用-AT91RM9200 the USB host and USB device code ADS1.2.USB-Device test procedure: Because the procedure is running in SDRAM, and so we have to initialize SDRAM (available for the initial basic boot procedure, followed by Can not reset or power off), then Run this program, the program to run after connecting USB port, the computer will be prompted to detect the new hardware, installing hardware drivers after the computer will atmusb6119.inf virtual USB port to a serial port to use

Discussing embedded systems in general is difficult, because each embedded system is unique. Rather than presenting a list of general principles for handling embedded development issues, this book presents examples of problems encountered and solutions to those problems using real hardware and software. In that sense, it is a “cookbook” for developers that offers design “recipes” that can be elaborated on or modified as needed to solve other design problems.

flash测试代码，它主要是针对SST39VF1601进行测试，主控制器是44B0。-flash test code, it is mainly directed against SST39VF1601 test, the main controller is 44B0.

ST7920液晶控制器的AVR程序，有反白程序。图片显示程序等等。代码很精简，用串行方式传输，只需要三根控制线就可以了。-ST7920 LCD controller AVR procedures, anti-white programs. Image display program and so on. Code is very simple to use serial transmission, only three control lines on it.

此程序代码是基于达芬奇系列DM6446嵌入式开发之驱动程序开发示例程序，该程序包中包含C语言源程序demo.c,test_demo.c和Makefile文件。该程序简洁明了，旨在说明驱动程序的框架结构，以及嵌入式驱动程序开发的步骤，对嵌入式驱动程序开发入门的同志非常有帮助。该程序经过反复的调试运行，没有错误，可直接运行。 调试步骤        1、仔细读目录中的代码：demo.c,demo.h,test_demo.c。               分析各部分代码的功能，以及应用程序和驱动程序的调用，数据读写的方法和流程。        2、仔细读目录中的Makefile文件，理解文件中各个语句的功能。
