利用信号量进行多线程通讯 首先在主程序中建立两个线程，然后设置信号量，每个线程循环等待符合要求的信号量，只要满足条件，则线程执行。该例为多线程通讯的简单实例，只是展示了原理-Signal was carried out using multi-threaded communication first in the main program to create two threads, and then set the semaphore for each thread to wait for

这是一个多线程的串口通信例子，可供大家借鉴-This is an example about multiple thread communication with serial port.

这是一个网络称重的服务器端,可以级连,多线程通讯,是一个学习的好例子!-This is a network load of the server side, can be cascaded, multi-thread communication is a good example of learning!
