【摘要】 1-Wire总线完成数据的传输只需一根数据线,与基于两线的I2C总线(集成电路内部总线 )和基于三线的SPI总线(串行外围设备接口总线)相比, 1-Wire总线的硬件接口更简单更可靠.本文介绍了 1-Wire协议的体系结构模型、接口时序和电气特点,并以基于 1 -Wire总线的多路温度数据采集系统为例介绍了如何实现该总线技术.更多还原

【Abstract】 Wire Bus only needs a data line to carry out data transfers.Comparaed with I2C Bus(Inter-IC Bus) and SPI Bus(Serial Peripheral Interface Bus), 1-Wire Bus interface is more simple and credible.This article introduces 1-Wire network protocol architechture model,and 1-Wire network interface timing and electrical feature.Italso takes a system of multi-drop temperature data acquisition as an example to introduce how to build a MicoLAN based on 1-Wire network protocol.更多还原
