串行总线芯片在单片机控制系统中的应用

The application of serial bus in single-chip control system

由于串行总线的连线少,结构简单可以直接连接各个设备,采用串行总线设备可以降低系统成本,PCB成本、提高系统的可靠性。所以串行总线器件的应用越来越广泛。本文介绍了几种常用的串行通信总线(单总线、I2C、SPI)以及串行通信器件在温度控制系统中的应用实例。

Serial bus only requires a few port pins for communication. The structure is simple and can connect with many devices easily. Serial bus device can lower system cost reduce board space requirements and increase reliability. So serial device is more popular than before. This paper discusses several normal serial bus : 1_Wire,I2C,SPI, and the using of these devices in the temperature control system.
