﻿1. 功能说明
    此例程展示在 RT_Thread 系统调用调度器锁

2. 使用环境
    硬件环境：工程对应的开发硬件平台 
    开发板：   N32WB452XL_EVB V1.1

3. 使用说明
    描述相关模块配置方法；例如:时钟，I/O等 
         1. SystemClock：144MHz
         2. GPIO：日志：TX--PA9  RX--PA10，波特率：115200

    描述Demo的测试步骤和现象 
         1. 编译后下载程序复位运行
         2. 接好串口打印工具
         3. 本例程创建两个线程，thread1 线程和 thread2 线程，thread2 线程优先级高于 thread1, thread1 线程将调度器上锁后，在解锁之前，不会切换到 thread2 线程，查看打印日志

4. 注意事项
    无

1. Function description
    This routine is shown in the RT_Thread system call scheduler lock

2. Use environment
    Hardware environment: development hardware platform corresponding to the project 
    Development board:      N32WB452XL_EVB V1.1

3. Instructions for use
    Describe the configuration method of related modules; for example: clock, I/O, etc. 
        1. SystemClock: 144MHz
        2. GPIO: Log: TX--PA9 RX--PA10 Baud rate: 115200

    Describe the test steps and phenomena of Demo 
        1. After compiling, download the program to reset and run;
        2. Connect the serial port printing tool;
        3. This example creates two threads, thread1 thread and thread2 thread. Thread2 thread has a higher priority than thread1 thread. 
            The thread1 thread will lock the scheduler, before unlock, will not switch to the thread2 thread, see the print log

4. Matters needing attention
    None.
