Interface Design of PC Based on Serial Communication

At present, the automation equipment is mainly through the serial port to communicate. Mainly through the PC machine as the host computer to carry out the serial port debugging, in the serial communication debugging. Because of the large size of PC and the limitation of industrial field environment, the communication failure cannot be quickly located and eliminated, which increases the difficulty of debugging. By using cross platform C + + application development framework QT to develop portable equipment serial communication interface program, will be portable serial communication interface program is transplanted to the arm development board, through the arm board to serial communication automation equipment debugging, reduce debugging difficulty and improve the working efficiency.
