摘要
针对嵌入式服务器、局域网需要与串行口通信的要求,提出基于MPC860与ST16C654的设计方法。采用MPC860与ST16C654作为主要器件进行电路连接,采用嵌入式实时多任务操作系统VxWorks开发程序,实现串口数据包的异步收发。进行单通道每秒20次连续收或发5字节实验,无丢失包。该设计已成功应用于网络设备开发中。
Considering the requirement of the communications between embedded server or LAN and serial, the paper puted forward the design method based on MPC860 and ST16C654.The circuit based on MPC860 and ST16C654 was designed. VxWorks,a embedded real-time muhitask operating system was used while programming. The asynchronous communications of serial data was realized. The experiment using a single channel to send or receive five bytes continually twenty times per second has no packet loss.This design has been applied in network equipment developing successfully.
