摘　　要：分析了MQX实时操作系统设备驱动管理模式,给出了该模式下底层驱动程序设计开发的基本步骤和方法.针对该模式存在设备驱动过于依附操作系统,不利于移植和复用等问题,在I/O子系统层和底层设备驱动层增加接口驱动层,用来解析和传递设备参数,并将设备驱动剥离操作系统,有效地提高了驱动构件的移植和复用效率.实验结果表明,该方法设计的设备驱动构件稳定可靠.The MQX real-time operating system device driver management mode is analyzed, and the basic steps and methods of the underlying driver design and development under this mode are given. Aim at the problem that the device driver is too dependent on the operating system in this mode, which is not conducive to porting and reuse. By adding an interface driver layer at the I/O subsystem level and the underlying device driver layer to analyze and transmit device parameters, the device drivers are stripped from the operating system, and the efficiency of porting and reuse of the drive components is effectively improved. Experimental tests show that the device drive components designed by this method are stable and reliable.
