PIC单片机与PC串行通信的实现

The Realization of Serial Communication between SCM (PIC kind) and PC

近年来PIC单片机的应用场合越来越多,但有些场合PIC单片机内部串行口不稳定,有些PIC单片机内并没有提供串行口,所以有时串行通信必须通过自己设计的硬件电路和通信软件来实现.利用面向对象的程序设计语言和MSComm控件,使用文中的硬件接口电路及源程序,实现了PIC单片机与PC机简洁串行通信.

In recent years, the SCM (PCI kind) is more and more widely applied. However, on some occasions, defects arise, such as the instability of internal serial interfaces of SCM (PCI kind), the lack in internal serial interfaces,based on which the serial communication can only be realized with the self-designed hardware circuit and communication software. This paper describes the realization of the serial communication between the SCM(PCI kind) and the PC with the use of the object oriented design language, MSComm controller, the hardware interface circuit and procedure.
