Description: 1 本程序是我自己移植，只使用KEIL进行过软仿真，测试没有发现问题。支持从任何一个中断服务程序里释放信号量。
2 此代码作为参考和学习使用，如果在使用过程中造成损失，本人不负任何责任。
3 此代码作为参考和学习使用，因为里边有UCOS-II，如果要作为商业使用请给UCOS付费
欢迎大家测试，在实践中检验一下，多提提意见。谢谢，我会根据大家测试结果第一时间解决问题。
上一个版本发现了漏洞已经修正，已经在STM32F103CBT6上通过了测试： -A program is my own transplant, carried out using only soft KEIL simulation, testing did not find the problem. Support from any one of interrupt service routine release semaphore. 2 of this code as a reference and learning to use, if in the use of the process of loss, I no responsibility. 3 of this code as a reference and learning to use, because inside has UCOS-II, if we as a commercial use, please pay uCOS welcomes U.S. test, in practice, testing about more than make a suggestion. Thank you, I will in accordance with the first U.S. test results to solve the problem. The previous version has already found loopholes in the amendment has passed the test on STM32F103CBT6:

Description: Purpose
Aim to setup a small system above the OS layer , implement the message queue of process or thread and simulate the function of watchdog used to detect the deadlock of the system.
- introduction
1. Purpose
Aim to setup a small system above the OS layer , implement the message queue of process or thread and simulate the function of watchdog used to detect the deadlock of the system.
2. Method
Using window API to create serval thread and create a message queue for each thread to control the message exchange between the different treads.
3. Files
Projectmain.h------ structs , enums ,and claim of functions
ThreadSemaphore.c------- extend the Windows semaphore API
ThreadQueue.c------- message queue file (send to, receive from ,create and destroy queue )
ThreadFrame.c-- 1) create all the task for test
2) control the message handling
3) control the thread running
4)functions of watchdog
5) a hardware timer simulator to create timeout message every 1 sec
4 task :
Thread_IDLE,-- lowest prority , interact with user and obtain a semaphore which will be waitted by Thread_LOST later
