In this post we are going, just for once, to focus mainly on theoretical concepts, to explain the microcontroller performance when using direct and reciprocal frequency measurement. Direct frequency measurement means that we are counting the wave fronts during one second. Hence we get a direct measure of the number of repetitions of the […]
Using I2C to feed frequency measurements. Easy!
How to use I2C to feed frequency measurements from the Arduino compatible precision frequency counter to another device? The Arduino compatible precision frequency counter Freq_LF_HF can communicate over an I2C serial network. In the example presented below we will be using Feq_LF_HF board in master mode to send frequency values to an Arduino Nano board […]
