摘要
在凌阳公司的SPCE061A单片机和讯通公司的PTR8000通讯模块组成的无线通讯系统中,由于PTR8000通讯模块只具备SPI通信接口,而SPCE061A单片机不具备SPI接口,为此采用了SPCE061A通用I/O口和软件模拟SPI通信方法,实现了二者之间的通信,从而充分发挥了SPCE061A和PTR8000各自的优势。此方法同样适用于解决其他非SPI接口单片机系统与具备SPI接口外围器件的通讯问题。
In the system of wireless communications which is composed of SPCE061A and PTR8000,PTR8000 only has interface of SPI while SPCE061A doesn＇t have SPI interface,it adopts SPCE061A general I/O interface and software simulative SPI. Adrantages of SPCE061A and PTR 8000 are developed. This method can be used in other single chip computer system to solve the SPI communication problem.
