frequency counter circuit diagram This document describes the construction of small frequency counter with a cheap PIC microcontroller and a few seven-segment LED digits. The main features of the frequency counter are: In the circuit, use PNP transistors for the CA display instead of NPN for T1 to drive the 5th digit, furthermore connect D1..D4 with reverse polarity, and

Frequency Counter: Schematics and C code for a PIC frequency counter circuit operating up to about 50MHz. This PIC frequency counter circuit uses a multiplexed seven segment display to provide 8 digits and uses timer 1 to count edges of the input signal and Timer 0 to count time.. It uses the simpler method of direct frequency measurement which means that the input event (for which you want to
To make calculations trivial using a 1 second gate time (T) gives a direct reading of frequency from the edge counter. Making a frequency counter for frequencies up to 65.536kHz is easy as the counters in a PIC chip can count up to 65535 without overflowing. Up to 65.535kHz all you do is wait for 1 second while the count accumulates, read the
