• 下载

    https://github.com/FreeRTOS 仓库有很多freeRTOS关于协议栈的实现，HTTP，TCP，MQTT等

    这里只需要核心代码去模拟

    https://github.com/FreeRTOS/FreeRTOS-Kernel

  • 安装cmake

    省略，可以前往 LVGL-vscode模拟

  • vscode安装各种插件

    省略，可以前往 LVGL-vscode模拟

  • vscode项目配置

    .vscode/settings.json文件

    {
    "cmake.sourceDirectory": "E:/_1/embedded-study/freeRTOS/vscode/FreeRTOS-Kernel",
    "cmake.cmakePath": "E:/Program Files/CMake/bin/cmake.exe"
}
    • cmake.sourceDirectory：cmake那个CMakeLists.txt文件目录
    • cmake.cmakePath：前面安装cmake的目录

  • 移除不需要的文件/文件夹

    • 删除所有目录下的CMakeFile.txt
    • 删除其他无用文件。如图：
    1

  • 测试

  • 编写测试程序

    main.c

    #include <FreeRTOS.h>
#include <task.h>
#include <stdio.h>

void vTask(void *pv)
{
    (void)pv;
    for (;;)
    {
        printf("Hello World\n");
        vTaskDelay(1000);
    }
}

void main(void)
{
    xTaskCreate(vTask, "Task", configMINIMAL_STACK_SIZE, NULL, 1, NULL);
    vTaskStartScheduler();
}

  • freeRTOS配置文件

    FreeRTOSConfig.h

  • CmakeList.txt文件
