![]() Using the 1 second measurement time also gives a frequency resolution of 1 Hz. number of input periods counted in 1 second is the frequency in Hz. Since the measurement time is 1 second the final count is actually the frequency of the input signal i.e. All you do is count 1e6 processor clocks (Timer0) to give a 1second count period. The crystal oscillator is chosen to be 4MHz (Fosc) so that the processor internal clock is 1MHz (Fosc/4). It uses Timer 1 in 16 bit counter mode to count the input signal edges and overflows of the counter are accumulated to give the total count in multiples of 65536.Adding the current value of the counter at the end gives the total count. This PIC frequency counter project uses an LCD to display the frequency and PIC timer 1 to measure the input signal and Timer0 to measure the timing period. All you need is a PIC microcontroller (or any microcontroller that has a high speed timer input module) and a 2 line LCD display (the standard HD44780 one is the one used here).
