 The firmware command "''i2c scan''" is VERY useful when making sure that the hardware is correctly setup and configured.  Issuing this command will perform a scan of ALL I2C addresses from 0x00-0xFF to see what responds.  You can only run this with direct microcom connection to the AVR running in DEBUG mode.  See also [[hah_microcontroller]] The firmware command "''i2c scan''" is VERY useful when making sure that the hardware is correctly setup and configured.  Issuing this command will perform a scan of ALL I2C addresses from 0x00-0xFF to see what responds.  You can only run this with direct microcom connection to the AVR running in DEBUG mode.  See also [[hah_microcontroller]]
