A wide range frequency meter is an useful tool for an electronics lab. This projects describes a frequency meter based on AT90S231 microcontroller that can measure input frequencies up to 50 MHz. The measured frequency is displayed on 6 digit multiplexed seven segment displays. It uses two external high-speed 8-bit counters (74HC590) in cascade. Output B frequency: 16 MHz / 64 / 255 / 2 = 490.196Hz; Output B duty cycle: 50 / 255 = 19.6%; Phase-correct PWM divides the frequency by two compared to fast PWM, because the timer goes both up and down. Somewhat surprisingly, the frequency is divided by 255 instead of 256, and the duty cycle calculations do not add one as for fast PWM. It is an 8-bit AVR RISC-based microcontroller chip.

Frequency is defined as (Number of events) / (time in seconds) and measured in Hz. 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. If you use an external crystal or resonator, the device determines the frequency. If you use the AVR's internal 8 mhz reference, it will not be exactly 8 mhz but something close. While this is very easy to do and requires no external components, the system cost is that you get a clock that will change with temperature.
