摘要
文中介绍PC／104模块及其外围接口电路设计,并讨论该接口电路所需要考虑的电平匹配、功率驱动以及抗干扰问题,最后还进行相应的软件设计,并将所设计接口电路用于某设备的开关量检测,实践证明工作状态良好。
This paper introduces the PC/104 module and its external interface circuit design, and many problems, such as PWL matching, power drive and anti-jamming in the.circuit, are discussed. At last the software design is made; this interface circuit has already been applied in the detection of switches of certain equipment and worked well.
