We know that this development laborious and costly, so based on the frequency counter as the research object, the use of Proteus powerful microcomputer processor simulation, combining with Keil compiler, presents a simple and easy to operate the frequency counter design and complete the simulation test. In this paper, we design a microcontroller AT89C51 as the core of the digital frequency counter, the hardware part mainly by shaping circuit, single chip microcomputer minimum system and display units, the software design is composed of some functional modules, such as initialization module, crystal vibration module, data display module as well as the reset module and so on. This method is good enough to make up the flaws of the traditional development mode. The frequency counter by the LCD display and a single chip microcomputer AT89C51, and clock signal generator, the measured frequency range between 1 HZ and 100 KHZ.
