Description: Use 555 generates a square wave signal is input to the microcontroller to measure frequency. 2 frequency measurement method: by the number of pulses per unit time is defined frequency, the frequency of the signal obtained. Choose the appropriate time base, such as one second, as a counting gate, get a frequency count value is within the gate signal. The method is suitable for measuring high-frequency signals. 3 digital display of frequency measurement results
