Function descriptions:
|
|
|
This sample demonstrates the application of FreeRTOS list related API functions
|
|
|
to realize the insertion and deletion of list items. Observe the process of
|
|
|
implementing the insertion and deletion of list items 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

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。
|
|
|
Task1: 每隔500ms打印一次"Task1 is running"信息。
|
|
|
Task2: 创建列表、列表项，插入、删除，打印列表项地址信息。每隔1s打印一次"Task2
|
|
|
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 every 500ms.
|
|
|
Task1: Print the "Task1 is running" message.
|
|
|
Task2: Create lists, list items, insert, delete, and print list item address
|
|
|
information.Print the "Task2 is running" message every 1s.
