As you may know I’m a fan of the I²C interface. You can find a sensor or board for just about anything that uses this 2 wire protocol. But sometimes you want to use some part that doesn’t work with I²C. Using the ATtiny3217 may be the perfect solution. The Atmel ATtiny3217 is a powerful micro that can interface with your new part or hardware and create an new I²C slave interface.

I²C continues to thrive as a standard for connecting microprocessors to sensors and other peripherals. Two major companies have adopted a standard connector for I²C called Qwiic, which makes I²C even more user friendly. Sparkfun chose a small JST 4 pin connector and Adafruit has also adopted the same connector for all of their I²C boards.

I²C is a standard protocol for connecting various electronic parts to a microcontroller. It is pronounced “eye squared see” and stands for Inter-Integrated Circuits. To connect an I²C part you only need to use two pins on the micro (besides Vcc and GND), one for data and one for the clock signal.
