    Hello,

    I am trying to find an smbus type library for the Ci20. Does one exist? Or is there any examples for using i2c on the board?

    Thanks.

    Hi,

    You could use i2c-tools in Linux. e.g. i2cdetect, i2cset, i2cget, i2cdump
    https://packages.debian.org/jessie/i2c-tools

    FYI. There is a slight bug in the i2c hardware. The detection isnt fully functional. But if you know something is connected to your bus at a certain address. read/write works.

    Regards,

    Thanks. I had already installed i2c-tools and they do not find the device bus. I may just use serial.
