Frequency counter is a very important test instrument for Radio Amateurs, especially those who wish to develop or test circuits. There are lots of frequency counters in the market but building one was never so easy & exciting with Microprocessors doing lots of work for us.
This Frequency counter Project is based on PIC16F84A Microprocessor chip manufactured by Microchip and software provided by amateurs to help understand PIC programming.
Counter can be configured by 4 push buttons for IF off-sets and other EEProm functions. Refer to config. doc given below for details.
This Frequency Counter is designed for radio amateurs looking for simple frequency display for their VFO frequency or QRP home made rigs. It may also be very useful to add an LCD display to your antique radios.
