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
.
.
