摘　　要：目前许多角度编码器将采集后的角度数字量通过SSI接口输出,供处理器读取。基于C8051F单片机内部所带PCA0可编程计数器阵列外设,设计一种适用于读取SSI接口信号的接口。通过实际应用运行,证明该设计方案稳定可靠,并且配置灵活,完全符合SSI接口协议标准。Nowadays there are so many angular encoders use SSI to output digital data. In this article, C8051F MCU’s digital peripheral Programmable Counter Array （PCA0）is used to design an interface to acquire the Synchronous Serial Interface （SSI）. Through practical operation,it is verified that this design method is stable and reliable, also flexible,and in full compliance with the SSI protocol standard.
