Connecting peripherals without dedicated I2C interfaces with I2Cwrapper #Arduino

I2Cwrapper enables you to connect peripherals without dedicated I2C interface like stepper motor drivers, TFT-displays, sensors, etc. to an I2C-bus. It uses an Arduino-compatible device which acts as an I2C target device and “translates” between the I2C-bus and the non-I2C peripheral.

To do so, the IC2wrapper framework “wraps” library function calls and return values and transmits them between I2C-controller and I2C-target. From the controller’s perspective, using the device over I2C is very similar to directly using it, so that existing code can be adapted easily.

  1. I was wondering how this compares to the SeeSaw library which seems to do much the same thing?

    I ask mainly because I was about to embark on writing something similar for a project, which would be something more akin to an "auto configuring" system where the i2c modules would identify what they are, and the controller would be able to pick that information up and use the modules (there’s a lot more to it than this of course, but this is the lowest level of the system).

    I may build what I need on top of this or the SeeSaw code..

  2. Adafruit remains committed to Seesaw but it’s always great to see how others tackle similar situations.
