Because of randomness and complexity of the low frequency noise, the low frequency noise generator consists of PC and PIC single chip microcomputer. The generator can output what have drawed just dragging the mouse by customer. This paper introduces the software and hardware design of the generator. The method to access is discussed in detail,especially how to realize the serial communication between PC and PIC single chip microcomputer by utilizing MSComm control box of VB. To ensure the correction and reliability of the communication,the check method is also discussed. This generator can pro...
