With the rapid development of the Internet, remote control of the movement of devices through the Internet has become a research focus. The article presents a design that can connect a device to the Internet directly through an embedded Web server. Taking the example of the remote control of step-in electromotors, we design a minimal functional embedded Web server on ARM. It analyses the Internet packets and achieves the control information which is included in the HTTP data. According to the control information, the way of counter interrupt is adopted to control the eleetromotor. On this basi...
