摘要
TERN公司开发的586-Engine微控制模块具有精度高可靠性高的特点,适用于工业程序控制和高精度数学计算。为了实现高实时性、高传输波特率的要求,本文提出了一种基于UR8的异步串行通信扩展方案,并完成系统的软硬件设计。文中详细介绍了基于UR8的串口扩展方法,给出了接口设计电路原理图、初始化配置例程以及程序流程图,并对设计细节进行了详细阐述,最后给出试验结果。
Features such as high performance and reliability make the 586-Engine micro control module which is developed by TERN Corporation ideal for industrial process control and applications requiring intensive mathmatical computation. Ac- cording to the requirements of high real-time and high transmission baud rate, an extended scheme based on asynchronous serial communication of UR8 is proposed,and an implementation of hardware construction and software system is given. This paper presents a detailed description of the serial port expansion method based on URS,and introduces the schematic diagram of interface circuit,initial configuration routines and receiving program flow chart. Finally, the test results？are presented.
