C bus devices are located at /dev/i2c*. On the BeagleBone used with the U3810A I
2
C Bus 1 is
connected to the Arduino J8 connector and the J11 connector. The I
2
C Bus 2 is connected to the LCD
Display and the U3810A EEPROMs.
In this section you are going to connect an I
2
C device to the U3810A. First the connection will be
verified with Linux command line functions. Then, run a program that will compare the analog sensor
to the digital sensor.
