SPI接口单线应用

Single Bus application of SPI interface

为解决I/O口数据传输的速率问题,提出SPI接口的单线应用方案,分析该方法的可行性,并在单片机ADμC812与射频无线通信模块nRF2401间的接口设计中得到了应用,验证该方案的有效性。该方案具有电路设计简单、数据传输速率高等优点。

For solving the speed problem of data transmission about general I/O interface, in this paper scheme of single bus application in SPI interface is introduced analysed the feasibility about method, and applied this method to the interface design between MCU ADμC812 and the wireless radio frequency communication modular nRF2401, which verifies this scheme valid. This scheme has some advantages of simple circuit design and higher data transmission speed.
