Troubleshoot the BeagleBone Black I2C Interface

Trying to create a connection with an I2C device produces an error:

addr = scanI2CBus(bbb,'i2c-1')
i2csensor = beaglebone.i2cdev(bbb,'i2c-1',char(addr))

The error states that another connection exists to the device at that address. Create a connection to a device that has a different address, or clear the object for the current connection.

Note

The hardware enables HDMI (orange) pins by default. MATLAB® Support Package for BeagleBone® Black Hardware does not support HDMI. To disable HDMI, see the BeagleBone Black hardware documentation.
