Following the instructions below to start using your BeagleBone Weather Cape:

  1. Mount the BeagleBone Weather on top of BeagleBone.
  2. Make sure the micro SD card using with BeagleBone has latest Angstrom image.
  3. Power up the BeagleBone using a 5V DC power supply.
  4. Connect the BeagleBone to a computer via USB cable.
  5. Open a Terminal application (Teraterm, Hyperterminal, etc) and open a new connection with following settings:
    • Baud rate - 115200
    • Data – 8 bit
    • Parity – none,
    • Stop – 1 bit
    • Flow control – none.
    • You should see an Angstrom log in prompt on the terminal window. If not, press Enter to show the log in prompt
  6. Run the following command to display the outputs of all sensors:
    • for sensor in /sys/devices/platform/omap/omap_i2c.3/i2c-3/*/*_input ; do echo -n "$(basename $sensor): " ; cat $sensor ; done
  7. You should see something like this on the terminal window:
    • lux1_input: 27
    • humidity1_input: 38143
    • temp1_input: 26927
    • pressure0_input: 101264
    • temp0_input: 270
  8. The I2C outputs are interpreted as 27 lux, 38% humidity, 27 degrees C and 1013 millibar.
