功能描述：
|
|
|
此样例演示了FreeRTOS三个任务依照优先级大小依次切换的实验。通过串口log，观察任务
|
|
|
切换顺序。

Function descriptions:
|
|
|
This sample demonstrates an experiment in which three FreeRTOS tasks are
|
|
|
switched in order of priority. Observe the switching order through the serial
|
|
|
port log.

测试环境：
|
|
|
测试用板：PY32F403_STK
|
|
|
MDK版本：5.28
|
|
|
IAR版本：9.20
|
|
|
GCC版本：GNU Arm Embedded Toolchain 10.3-2021.10
|
|
|
|
|
|
Test environment:
|
|
|
Test board: PY32F403_STK
|
|
|
MDK Version: 5.28
|
|
|
IAR Version: 9.20
|
|
|
GCC Version: GNU Arm Embedded Toolchain 10.3-2021.10

|
使用步骤：
|
|
|
1. 编译下载程序到MCU，并运行；
|
|
|
2. 通过串口调试助手打印的log信息，观察任务执行过程。
|
|
|
任务执行顺序为：Task3->Task2->Task1
|
|
|
Task1: 打印"Task1 is running"信息。
|
|
|
Task2: 打印"Task2 is running"信息。
|
|
|
Task3: 打印"Task3 is running"信息。
|
|
|
|
|
|
Example execution steps:
|
|
|
1. Compile and download the program to the MCU and run it;
|
|
|
2. You can use the log information printed by the serial debugging assistant to
|
|
|
observe the task execution process.
|
|
|
Task execution sequence: Task3->Task2->Task1
|
|
|
Task1: Print the "Task1 is running" message.
|
|
|
Task2: Print the "Task2 is running" message.
|
|
|
Task3: Print the "Task3 is running" message.
