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.
