| Summary: | The positioning of servo motor is controlled by sourcing the servo with PWM signal of varying pulse width. The pulse width of the PWM signal can be manipulated through a web interface hosted on ARM board programmed as an embedded HTTP server where control application by an embedded system can be monitored and managed remotely. Embedded HTTP server network stack is based on modified TCP/IP protocol suite where only important features are used. A web server for user interface is created using HTML and JavaScript is hosted together with the network stack. The ARM board is equipped with RTOS to enable real time control response between the interface and the servo motor. Two tasks namely PWM and TCP/IP task are configured to enable execution from RTOS based on their priorities. Under executions, a slider inside web interface controls the turning of servo motor with the degree of rotation is displayed on the web interface. |
