  Hardware Setup

  As per any new device setup, we recommend becoming familiar with the RevPi Core + RevPi DIO official quick start guide by Revolution Pi. Then be sure your to assemble the RevPi Core + DIO correctly referencing the below articles for additional details, as needed.

  • Connect your RevPi Core to Ubidots

  • Connecting modules

  • Mounting modules on a DIN rail

  • Connecting the power supply

  • Status LEDs DIO

  • Digital in and outputs

  • Configuration RevPi DIO

  • Updating firmware on modules (Jessie)

  Firmware setup

  1. First we must have access to the inputs and outputs of the Revolution Pi. The "python3-revpimodio” module provides all access to the IOs of the Revolution Pis, and can be programmed very easy with Python3.

  Based on the image installed in your RevPi Core reference this guide to make the installation properly. If you have the Jessie Image on your core, simply install the module from the Kunbus repository running the commands below in the RevPi Terminal:

  • Update system packages: 

  sudo apt-get update
  

  • Install:

  sudo apt-get install python3-revpimodio2
  

  • Update Distribution (all):

  sudo apt-get dist-upgrade
  

  2. Next, install the requests module for python3 by running the command below in the RevPi Core terminal:

  sudo apt-get install python3-requests 
  

  3. Once each of the commands above have finished, verify everything as accurate by opening Python3 into your RevPi Core terminal and importing the module previously installed.

  Open the Python3 by running the command below into the RevPi Core terminal:

  python3
  

  Once you have access to Python3, import the modules ''revpimodio2" and "requests" as is shown below:

  import revpimodio2 import requests
  

  If receive and error messages after importing the module, verify the issue shown and try again.
