[mircemk] had previously built a frequency counter using an Arduino, with a useful range up to 6 MHz. Now, they’ve implemented a new design on a far more powerful STM32 chip that boosts the ...
Frequency meters measure repetitions per unit of time (frequency) and display it using a needle or graphic pointer. Industrial frequency meters are used in radio frequency (RF) and microwave ...
This frequency meter project squeezes a lot of performance out of the ATtiny2313 microcontroller. That chip does all of the work, measuring the frequency on the input pin as well as multiplexing ...
