I2C and WiiChuck libraries. in DesignLab Libraries Posted June 11, 2015 · Report reply Is there example code available yet for the use of the I2C? I have been trying unsuccessfully to get I2C working on the papilio pro. Ultimately, I went in another direction for my project, and since then both my papilio pro and papilio one have been sitting unused. I really need working I2C, otherwise I have two expensive paper weights.
