The thesis focuses on an embedded DC motor control system which provides standard interfaces for issuing command and data acquisition. The interfaces include USB, TCP/IP network ...and an embedded real-time OS. The implementation of the USB interface is accomplished by the Philips PDIUSBD12 development board. The Implementation of the network interface is completed by an 8051 Base MPU and a Crystal/Cirrus chip. The real-time OS adopts MicroC/OS-II written by Jean J. Labrosse. Concerning the USB, we investigated the device’s firmware coding and application software coding. Users can command the motor and get the response of the motor through our USB interface. For the network interface part, we finished TCP/IP protocol firmware coding and constructed a web server that lets users communicate with motors through internet. In real-time OS, we analyzed and decomposed the whole DC motor control program into several efficient tasks. And we compare the differences between the motor control response
