基于RS485的简单现场总线通信系统设计，功能如下：单发单收，在发送状态，能够连续发送从0到99的数字； 单发单收，在接收状态，能够接收数据，并在数码管上正确地显示出来； 单发多收，在AB完成的基础上，接上多个接收设备，能够正确发送和接收； (Based on a simple RS485 field bus communication system design, the following functions: single single collection, sending state, can be continuously transmitted from 0 to 99 single single collection, in the receiving state, capable of receiving data and digital tube correctly displayed single overcharged, on the basis of completion of the AB, connected to multiple receivers, can correctly send and receive )

说明：  使用STM32F103实现和TMP102温度传感器的通信，程序已经实测，附有简单的说明文档。(Using STM32F103 to realize the communication with tmp102 temperature sensor, the program has been measured, with a simple description document.)
