摘要
介绍了一款PC104总线多功能扩展卡设计。采用了复杂可编程逻辑器件(CPLD)技术,集成了多路模拟量输入/输出、带光电隔离的开关量输入/输出及一个正交解码电路,接口协议与台湾研华PC工控机ISA总线板卡兼容,满足了嵌入式控制系统高集成度的设计要求,在实际应用中获得了良好的效果。
The design of a multi-function extended card based on PC104 bus is presented. It adopts the Complex Programmable Logic Device （CPLD） technology, and offers the five measurement and control functions： A/D conversion, D/A conversion, digital input, digital output and a circuit of orthogonal signals decoding. Its interface protocol is compatible with the cards of Advantech Co.,Ltd.. It meets the high integration requirement of embedded control system and gets a good effect in the practical application.
