RT-Thread支持多种平台和多种编译器,而rtthread_startup()函数是RT-Thread规定的同意启动入口。一般执行顺序是:系统先从启动文件开始运行,然后进入RT-Thread的启动rtthread_startup(),最后进入用户入口main(),如下图所示: 以MDK-ARM为例,用户程序入口为main()函数,位于main.c文件中。系统启动后先从汇编代码start...
DeviceDrivers文件夹中: 在DeviceDrivers文件夹中pin主要是实现驱动层代码到应用层的对接,具体实现代码是通过以下几个函数: _pin_read _pin_write _pin_control 同时还要把硬件操作相关Drivers中的rt_pin_ops结构体中的函数与rt_device_pin中的ops相关联; 最终_pin_read等三个函数可以通过rt_device_pin间接调用到...

RT-Thread 线程管理的主要功能是对线程进行管理和调度,系统中总共存在两类线程,分别是系统线 程和用户线程,系统线程是由 RT-Thread 内核创建的线程,用户线程是由应用程序创建的线程,这两类线 程都会从内核对象容器中分配线程对象,当线程被删除时,也会被从对象容器中删除,如下图所示,每 个线程都有重要的属性,如...
There's already a great thread where people are reporting what USB/Bluetooth items will and won't work on the Surface RT. According to Pluggable, a manufacturer of USB peripherals, the problem lies much deeper: Windows RT doesn't support any USB device requiring a driver, and support may ...
