Abstract:

PIC SCM is a microcontroller with rich peripherals and high performance.It is widely used in various control systems.In the computer control system,information is often exchanged between PC used as the upper machine and PIC used as the lower machine.This paper mainly proposes an approach of serial communication between PIC18F452 and PC based on Visual C++,and hardware circuit and communication source program are provided.Debugging experiments indicate that the hardware design and software development achieve the preplanned function requirements.Therefore,the method provides good reference for serial communication between PIC SCM and PC.

Key words: PIC SCM;serial communication;Visual C++
