前言
准备
1、GD32F系列开发版，我使用的事F427R-START开发版
2、安装有Keil的电脑，当前keil版本为v5.31.0.0
3、FreeRTOS版本 FreeRTOS Kernel V10.1.1
一、保留RTOS目录下这些文件
?
?
?
?
二、添加源文件到工程
?其中?heap_4.c 文件在FreeRTOS\Source\portable\MemMang文件夹下，
port.c在\FreeRTOS\Source\portable\RVDS\ARM_CM4F文件夹下

其余\FreeRTOS\Source下
三、头文件包含
?编译报错，找不到?FreeRTOSConfig.h文件
可以从官方移植的例程中找到这个文件，放到\FreeRTOS\Source\include下即可

编译报错，port.o and gd32f4xx_it.o有几个函数重定义，屏蔽掉gd32f4xx_it中的这几个函数
?编译通过
?测试程序

创建两个任务 LED1_task()和LED2_task()、分别里面都对LED进行翻转，现象两个LED分别均匀闪烁
