Sharing frequency values between Freq_LF_HF and Arduino Nano over I2C@100Khz

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 […]
