    Frequency Counter

    Description:

    The project is 1Hz - 40MHz frequency counter with voltmeter displayed on 8 digit LCD display.

    Micro controller:

    At90S4433

    Features:

  • Four ranges, with 10 Hz and 1Hz resolution to at least 40 MHz.
  • High sample rate (5 samples/sec or more) with averaging to remove jitter.
  • Programmable ± offsets and S-Meter display for receiver or transceiver.
  • Binary and BCD maths to provide direct reading of frequency with prescalers.
  • Low current single supply operation. Can be operated from a small battery for portable use.
  • Optional high speed PC telemetry.
  • Well documented source code is available, so the design can easily be adapted.
