CardKB as I2C keaybord on R. Pi

  • I'd like to use the CardKB as an I2C device on a Raspberry Pi (link for Pi setup).

    However, the following command produces no address for the keyboard and it does not work. Do I have to flash firmware to it? This is my 2nd CardKB because I broke the first one trying to flask firmware to it w/ the Arduino IDE.

    i2cdetect -y 1

    I don't get it. Why won't it work? Is my CardKB broken?

  • I mistakenly connected it wrong. It functions as a I2C keyb out of the box. I flashed it w/ the Arduino IDE to be a UART serial keyboad (i.e. terminal). Great! :)
