Abstract
This implements the ARM processor transplantation μC / OS-II embedded operating system and μC / GUI.Focuses on embedded hardware system design PID controller.Achieved by interaction through the touch screen, display real-time data and access to set the parameters for motor speed control.Carried out using lpc1766 hardware PID calculation and display of various man-machine interface.PID calculation and system data required to go through low level device drivers to get from the external device is required to develop drivers for the hardware.This article written driving AD, DA drive and touch screen drivers.
Keywords:μC/OS-II μC/GUI PID
