| 摘 要： | 1-Wire总线是低速总线，存在长时间的延时。为了提高DSP使用效率，利用TMS320F206的片内ASP(异步串行口)，采用UART(通用异步收发)方式，模拟1-Wire总线时序，实现与1-Wire总线数字温度传感器DS18B20的通信。提供了方便、高效的低速总线与高速处理器的接口。

| Abstract: | Wire bus is a kind of low speed bus which has long time delay. To increase the efficiency ,TMS320F206's on chip ASP(Asynchronous Serial Port) is used to simulate the timing of 1 wire bus and realize the communication between DSP and 1 wire bus temperature transducer by working at UART(Universal Asynchronous Receive and Transmit) mode. Thus an economical and efficient interface between low speed bus and high speed processor is obtained. |
