EECatalog.com both published and featured the first of a multi-part article “What is HALT?“, written by our very own Alan Brown, Marketing Communications Manager. In it, he introduces what HALT testing is, what it isn’t, and how it compares to other tests. Be sure to take a look!
Embedded Computing author Brandon Lewis, Technology Editor, interviewed our own Mark Featherston, Embedded Engineer, on Ubuntu Core. Be sure to take a look! Pages 18 and 19.
Nuts and Volts has published the article “Working with I2C Sensor Devices” in the July 2017 issue. It walks you through how to interface with an I2C device using a single board computer. Be sure to visit your local bookstore and pick up a copy while they’re available!
In a continuing effort to usher their spa into the 21st century and stay top of mind with customers, Bozeman Hot Springs set out to provide real-time pool temperature data for their customers. They found an off-the-shelf solution with Technologic Systems which could integrate with their existing commercial automation controllers and serve temperature data over a REST API.
This practical guide gives us an opportunity to take a relaxed approach to getting started with the TS-7553-V2 single board computer. We’re going to take a look at how to make our first connections, and setup the network. These are usually the first things we do before starting development. In the grand scheme of things, this is just a friendlier extrapolation from the official TS-7553-V2 manual, so be sure to keep it handy for more advanced topics and specific details. The only assumption being made is that you’ve purchased the TS-7553-V2 with a development kit, including the pre-programmed microSD card and enclosure with 128×64 px LCD and 4 button keypad. Right then, let’s get started!
This is a comprehensive and easy to read example C code designed to work alone or included as a library for dealing with general purpose I/O via the sysfs interface in Linux. It can easily be applied to any computer which utilizes the GPIO sysfs interface (both pro and maker boards). Getting started is a breeze. You just need to decide if you’re going to use it as a library, including it into your existing code, or as a stand-alone utility. We’ll talk about both in this article, but first and foremost, here’s the source code we’ll be working with:
Blistery cold weather is starting to sink in, which ought to ignite an instinctual desire to get your house in order and monitor it so the water pipes don’t freeze and burst. So, we’ll take a timely look at a project setting up some temperature probes in various areas, reading them, and reporting in a custom dashboard. A true home automation expert would take things further by setting up relays to turn on heat tape or even maybe some actuators to control water flow. Maybe next year, but for now, we just want to be able to monitor important areas of our home (in this case a cabin in Montana) and understand temperature patterns over time for better planning. As with most projects, there is more than one solution, especially if it depends on what you have on hand. At the time, the list of things in hand were as follows:
Let’s take a quick look at what it takes to read from the ADC inputs of a i.MX28 based embedded system using example C code provided by Technologic Systems. Now, while this can be generically applied to many i.MX28 based embedded systems, we’ll be working with a TS-7680. Right, let’s get started!
This practical guide gives us an opportunity to take a relaxed approach to getting started with the TS-7600 single board computer paired with the TS-ENC750 enclosure with TS-752 baseboard. We’re going to take a look at how to make our first connections, talk about the Linux environment, and setup the network. These are usually the first things we do before starting development. In the grand scheme of things, this is just a friendlier extrapolation from the official TS-7600 manual, so be sure to keep it handy for more advanced topics and specific details. The only assumption being made is that you’ve purchased the TS-7600 with a development kit, including the pre-programmed microSD card and TS-ENC750 and TS-752 baseboard. Right then, let’s get started!
The purpose of this guide is to assist in installing node.js on a Single Board Computer running Linux, and creating a simple, lightweight web server application which serves up a “Hello, world!” page. Once it is complete you can add further functionality to extend it on your own.
