I've done everything up to changing the port on my RPi Rev2. It says( http://learn.adafruit.com/adafruit-16-c ... it-library
) to make a change to the I2c default port but it seems like Im missing something. Everytime I use the sudo nano I dont get anything on the screen. I've tried from the home directory and from inside the Adafruit_PWM_Servo_Driver directory. Im doing something wrong, I tried running the example program but its not working so I know I have to change that port. I've done everything else up to this point right. Any help?
