用两块51单片机基于RS232实现单片机之间的串行通信。又从机检测到当地温度，然后由主机查询，从从机读得温度数据。该程序时C51程序。-MCU with 2 RS232-based serial communication between the SCM. And from machine to detect the local temperature, and then by the host queries, from the temperature data from the machine-readable too. The program C51 program.

通过DS18B20读取温度（范围-55C~125C，精确到小数点后一位），通过4位数码管显示出来。 当温度为正且百位为零时，不显示，当温度为负时百位显负号。当温度百位和十位都为0时0都不显示。-Read through the DS18B20 temperature (range-55C ~ 125C, accurate to one decimal), through four digital tube display. When the temperature is zero and 100, do not show, when the temperature is significantly negative at minus 100. When the temperature is 100 and 10 are not displayed 0:00.

网线测试仪程序，可测试网线长度（300M内），排序，用脉冲反波测试，时间*速度=距离的原理。-Cable tester program to test cable length (300M) with sorting, using anti-wave test pulse, time* speed = distance principle.
