8. Free PIC Firmware & PC WIN Software by Tony/I2TZK
Project is designed and developed for science students and Radio Amateurs, looking for economical frequency counter for their hobby work.
This counter may also be used as a frequency display for old ham
equipments. (IF Offsets may be configured by USB/PC)
Project uses simple diode detectors to
display signal level on second line of LCD as a Bargraph.
Those looking for more accurate freq/level measurement may look for FC3
or FC5 counters
which uses AD8307 to measure RF level very accurately in DBm, Vpp or RMS.
In FC3-SK, Usually, you configure PIC's internal
parameters using a Free PC software by I2TZK, enter IF
Offsets (if any), adjust back-light and if required, calibrate with an accurate frequency source and then use
