About this repo

General info

This project is simple low-cost digital frequency meter using a PIC 16F628A
originally created by Wolfgang Buescher, DL4YHF, (based on a work by James Hutchby, MadLab, 1996). This project is an ex MPLAB 8 project (MPASM Assembly compiler), ported to MPLAB X 6 project (pic-as Assembly compilator) by Aniello Di Nardo (IU8NQI)

Requirements

  • A PCB board based on the PIC16F628A designed by Wolfgang Buescher, DL4YHF (available already mounted also on Ebay, AliExpress, etc...)
  • Schematic available at: (https://qsl.net/dl4yhf/freq_counter/freq_counter.html)
  • MPLAB X v.6 with a XC8 PIC ASSEMBLER (pic-as) compiler
  • A standard (or advanced) PIC programmer board (eg: PICkit3, PICkit4, PIC K150, ...)
  • HEX available Here (raw) or Here (zip)

Change Log

2022-11-27

  • Porting to MPLAB X 6 (pic-as compiler)
  • Remember to set "-Wl,-PresetVec=0x0" in pic-as global options (Additional Options) of Project Properties
  • Added 10695000 Hz into IF Table
