The IoT Starterkit supports the Raspberry Pi with peripherals attached via a GrovePi shield and programmed in Python. In the example we use a Slide Potentiometer for the input of values that can be changed by the user as well as an LED and an OLED graphical display for visible output.

Starterkit running

Please follow these steps to get the example up and running:

  • Install a Raspbian Linux distribution following the instructions and downloadable images from https://www.raspberrypi.org
  • Configure the Raspberry Pi to have appropriate network connectivity (we support operation both without and with an HTTP proxy) and make sure your installation is up-to-date using the apt-get update; apt-get upgrade mechanism
  • Install urllib3 with sudo apt-get install python-urllib3
  • Install and test the GrovePi software as described at http://www.dexterindustries.com/GrovePi/get-started-with-the-grovepi/
  • Go to the GrovePi/Software/Python directory and do a sudo python setup.py install to install the GrovePi modules for all users of the system
  • Copy the file necessary for OLED support to the appropriate installation place with sudo cp grove_oled/grove_oled.py /usr/local/lib/python2.7/dist-packages/grovepi-0.0.0-py2.7.egg
  • Connect the Slide Potentiometer to A0, the LED to D4 and the OLED display to I2C-1
  • Install the files iot_starterkit_pi_and_grove_peripherals.py as well as config.py and configure for your HCP Trial account, credentials, Device and Message Types in config.py
  • Start the program as root (sudo bash lets you get root in case you have not been already) with python iot_starterkit_pi_and_grove_peripherals.py
  • Interact with the respective control and consumption mechanisms as described for desktop usage already
  • You can stop the running program with Ctrl+C
