将freeRTOS操作系统移植到stm32f103单片机上，测试时创建了五个任务，第一个控制led灯闪烁，三个为uart发送字符，一个uart接收处理任务，任务根据不同的优先级独立运行，测试成功(The freeRTOS operation system was transplanted to the STM32F103 microcontroller. During the test, five tasks were created, the first one was to control

主要是基于stm32F103增强型芯片的FreeRTOS开发环境搭建，可避免跑裸机，采用多线程方式使各个功能并行运行(FreeRTOS development environment setup.)
