|
This sample demonstrates the application of FreeRTOS queue related API functions
|
|
|
to realize queue in and queue out. Through the serial port log, observe the
|
|
|
process of task out and in queue implementation.

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: 任务执行1s后向队列KeyQueue发送一个值，任务执行2s后向队列BigDataQueue发
|
|
|
送一个数组首地址。计时清零，并重复这两个步骤。
|
|
|
Task2: 从队列KeyQueue接收一个值，接收成功，打印该值信息。
|
|
|
Task3: 从队列BigDataQueue接收一组值，接收成功，打印该组值信息。
|
|
|
|
|
|
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.
|
|
|
Task1: A value is sent to the KeyQueue after the task is executed for 1s, and
|
|
|
the first address of an array is sent to the BigDataQueue after 2s.
|
|
|
Time the reset and repeat the two steps.
|
|
|
Task2: A value is received from the KeyQueue. If the value is received
|
|
|
successfully, the value information is printed.
|
|
|
Task3: A set of values is received from the BigDataQueue. If the data is
|
|
|
received successfully, the set of values is printed.
