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)
- 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)
- 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
