DESCRIPTION

  • This document describes the construction of small frequency counter with a cheap PIC microcontroller and a few seven-segment LED digits.
  • Frequency range 1 Hz ... 50 MHz.
  • Five digits resolution (display for example x.xxxx kHz, x.xxxx MHz, or xx.xxx MHz).
  • Measuring signal amplitude can be up to 30 v 4-40 m passive crystals can measure.
  • Automatic range switching with different gate times.
  • Optional addition or subtraction of a frequency offset (programmable).
  • Very low component count: a PIC 16F628, 5 7-segment LED displays, a 20MHz crystal and a few resistors.
  • Optional (configurable) power-saving mode which automatically turns.
  • The display off if the frequency didn't change significantly within 15seconds.
  • USB 5V or DC5-12V power supply can be used.
