The Toradex blog encapsulates key insights and updates from our developers that would help provide an in-depth understanding of our product portfolio and its many advantages. Additionally, trends and tools are outlined in order to keep you abreast with developments at Toradex.
Cloud services have been a reality for some years already. Right now, one of the biggest concepts in the field is the Internet of Things, or IoT for short. When we electronics folk think of the cloud, the first thing that comes to our minds is connecting several devices to it and uploading data to be visualized, stored and analyzed - among other possibilities. Of course, other uses may come to mind, too.
One thing we don't always realize is that the cloud can be much more than simply an IoT tool, or something only large corporations have access to. We can make use of the cloud for everyday tasks, too. As a matter of fact, that's the motivation behind this article - taking a time-consuming task and using the cloud to simplify our lives a little!
Traditionally, microcontrollers are used for systems with deterministic real-time response. With the increasing need for higher performance, exciting UI and high-speed connectivity in end-products, many system designers are inclined to use application processors or SoCs with a feature-rich OS, a combination that may compromise real-time response. In this blog post, we present three approaches to add real-time behaviour in SoC-based designs.
Despite OpenEmbedded/Yocto being nice tools to generate your image, using the build system to compile and test tiny alterations applied to independent packages, although possible, can become confusing and slow. Read this post for details on the author's suggestion on how to alter the kernel and add the changes to OpenEmbedded/Yocto.
This is the third – and final – part of a series of articles introducing how to start developing an IoT solution. It focuses on using the cloud services provided by Azure to provide easily understandable data visualization and business intelligence. The embedded system chosen for this purpose was a Toradex customized SBC solution: the Colibri VF61 SoM + the Iris Carrier Board.
This is the second part in a series of three articles focused on the development of an IoT application. It goes on about the reading of sensors and sending of gathered data to the cloud. The embedded system chosen for this purpose was a Toradex customized SBC solution: the Colibri VF61 SoM + the Iris Carrier Board.
The concept of the Internet of Things is intrinsically related to the sending of data to the internet and its so called cloud services. People from the electronics field are everyday more easily connecting devices to the cloud as the evolution of technology is allowing the use of smaller and less power-consuming electronics as time goes by. Still there is an unanswered question for many of these electronics developers: how to make all of the gathered data useful? Because that is what the Internet of Things is about.
This 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.
