    Hello.
    I download mcp23017 library and install but I can,t add MCP23017 to I2c bus. I don,t have this element on "add device' list. What I,m doing wrong?

    Thank You!
    That was the reason why I didnt have this on my list.

    By the way, how to change I2c speed?

    Hi,
    one option is to change it here:

    sudo nano /etc/init.d/codesyscontrol
    .
    .
    echo 400000 > /sys/module/i2c_bcm2708/parameters/Baudrate
    .
    .

    Sure think you cold chance it outside from Linux command line too..
