Using Node.js and the Express Framework to Access the Colibri VF61 GPIO via Web


Monday, April 25, 2016

ColibriThis article is meant for anyone who wishes to quickly start developing an embedded Linux web application with access to the hardware GPIO, so that the user can control and/or monitor a system remotely. The application developed here, is based on the Colibri VF61 CoM (Computer on Module) by Toradex + the Iris Carrier Board, and a PCB with LEDs and switches. The main goals are to walk the reader through the process of developing Node code for accessing the GPIO via filesystem, building a simple yet user-friendly UI, and using the Express framework for hosting a minimal webserver that communicates with the client-side application by AJAX calls.
