This application note describes the implementation of a single pin measurement of frequencies up to 500kHz using the Timer 2 counter input pin. The code accompanying this document implements a frequency acquisition system that can be combined with a voltage measurement via the ADC to track both the frequency and voltage of the input signal. The measurement is displayed on an HD44780 compatible LCD screen. The display.c code accompanying this application note implements the routines necessary to output to the LCD display.
