The design of simple digital frequency meter based on SCM is proposed. Using STC89C52 as the core device, this complete measurement system is composed of the signal amplification shaping module,the digital LED tube display module and key control module, etc. The system program written by C language is compiled and debugged by the Keil software,and then simulated in the Proteus software. The system can realize the measurement of the frequency of different waveforms, which has the properties of small size, low cost, easy implementation.
