Description: 此程序是RS485从机通讯，包含3部分：接收帧程序、发送帧程序及执行命令程序。
从机通讯地址从地址开关读取4位
由于485的通信规约差别很大，这里只是提供参考，具体请参照自己的项目特点做修改,抛砖引玉。

Description: 本程序是一个AVR单片机通信小程序（其他单片机只要修改一下初始化即可），解压后用ICC软件打开项目即可编译，用到了RS232和RS485两种通信方式，两个串口，RS485走的9位数据位。很小的一个系统程序，只有三个C文件和一个H头文件。很适合在校学生和刚开始接触实际设计的新人。-This program is a small communication program AVR microcontroller (other microcontroller initialization as long as you can change it), with the ICC after decompression software to open the project can be compiled, use the RS232 and RS485 two kinds of means of communication, two serial ports, RS485 to go 9-bit data bits. A very small system program, only the three C files and an H header files. Very suitable for school students and the beginning of the actual design of the new contacts.

Description: 1） PC软件系统架构：摄像机+USB图像采集卡+PC电脑+RS485模块
2） 嵌入式系统架构： 摄像机+嵌入式系统平台
3） 火车速度<=40KM/H
4） 实现轨道左侧的信号灯颜色检测，红，白，蓝三色
5） PC软件接收RS485的信号进行相应的显示并通过485发送当前信号灯颜色
6） 嵌入式系统接收RS485的信号进行相应的显示并通过485发送当前信号灯颜色
7） 测试环境：雨、雾、冰雪等天气的白天和夜晚环境下
目前在PC上进行了初步的算法实验，演示视频见优酷（http://v.youku.com/v_show/id_XNTA3MzQ5ODA0.html）。大概的思路：首先检测出列出的2根轨道，得到大概的检测区域。并再用视频处理算法识别、跟踪信号灯。希望大家给些建议，使用哪种算法可以更好的跟踪信号灯。
-1) PC software system architecture: camera+USB image acquisition card+PC the computer+RS485 module 2) embedded system architectures: camera the+ embedded system platform 3) train speed < = 40KM/H 4) track lights on the left side of the color detection, red , white, and blue color 5) PC software receives the the RS485 signal corresponding display by 485 to send the current signal light colors) embedded system receives the RS485 signals corresponding display and signal light colors 7) by 485 to send the current test environment: weather such as rain, fog, snow and ice during the day and night environment on a PC preliminary experiments the algorithm, see demo video Youku (http://v.youku.com/v_show/id_XNTA3MzQ5ODA0.html). Approximate idea: first detected listed in the two tracks, and probably the detection region. And then the video processing algorithms to identify, track semaphores. We hope we can give some advice, which algorithm can better track the signal lights.

Description: DM430-L型开发板RS485通信实验，通过开发板与电脑进行数据通信，485接在UART1上
电脑端必备RS232转RS485模块，否则无法进行直接的连接RS485之间通过双绞线连接，如果距离近，可以不使用120欧电阻匹配电脑端通过串口调试助手操作，先将数据由电脑发往开发板开发板板会将收到的数据再发送到串口调试助手，接收采用中断模块，发送用查询板载的BSL模块可以通过跳线帽设置为USB转串口模式，笔记本电脑没有串口可以直接代替开发板的BSL区的RXD和TXD0连接，TXD和RXD0连接即可注意使用BSL模块作为USB转串口功能的时候，RTS和TCK跳线帽、DTR和RESET跳线帽要断开波特率更改请通过config.h文件，直接更改baud参数即可-Based on MSP430 485 communication protocol
