| 摘 要： | 在控制系统中进行现场控制的PC/104总线计算机往往需要以多种方式、同多种节点通信。本文介绍了按照PC/104标准开发带有四个串行口(两个RS-232、两个RS-485)和一个CAN总线接口的多功能、通用型扩展通信模块的方法,设计中所有的控制逻辑都由一块CPLD实现,CAN控制器与104总线之间的时序也由CPLD调整。

| Abstract: | Design and realization of a communication module with 4 serial ports a nd a CAN bus interface is presented in this paper. It is based on PC/104 standar d. All control logics in the module are occurred by a CPLD device. Time sequence between 104 bus and CAN controller is also adjusted by CPLD. |
