摘要: ASIC具有可编程性和设计的方便性,在电子产品中被广泛应用。一些ASIC具有非标准的串行通信接口,不能直接与PC进行串行通信。该文介绍了PC机与ASIC之间的串行通信实现方法——用单片机作为二者的通信桥梁,即用单片机的P1.0~P1.3口模拟ASIC的同步时钟线,串行输入输出数据线和控制线。

Abstract: ASICs are widely used in electronic products because of their programmability and convenience of design. Some ASICs have nonstandard serial communication interface that can’t communicate with PC directly. The realization of serial communication between PC and ASIC is introduced, in which a micro-controller is used as the communication bridge. That is, its P1.0~P1.3 ports are simulated as synchronous a clock wire, two serial in and out wires and a control wire of ASIC.
