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.

Key words: MQX, real time operation system, I/O subsystem, underlying driver
