Have you ever wanted to display your real-time sensor data on a webpage that can be viewed on any device with a modern web browser? How about a web page that serves as a dashboard for controlling and monitoring your embedded device in real-time? With WebSockets, you can do exactly that! In this article, we will briefly review what a WebSocket is, how it works, its benefits, and dive into a system-monitoring, dashboard-type application tutorial.
The Internet of Things has become an increasingly popular and susceptible attack surface for hackers, leading to some scary incidents. Significant and ongoing data breaches and malware infections have been reported with Ethernet-enabled baby monitors, medical devices, cameras, refrigerators and automobiles, to name a few. [ 1, 2 ] In this article we will give a bit of understanding into the TLS protocol and its benefits for IoT and Ethernet-enabled systems. We’ll also get you going with a tutorial on how to test a TLS connection between a PC and a NetBurner Serial to Ethernet Device.
It’s amazing what can be done with a NetBurner Embedded Core Module, creativity, and some ingenuity. The digital and analog world can ALL be yours… or at least you can do something super cool! At NetBurner we feel the annual SparkFun Autonomous Vehicle Challenge (AVC) is a perfect opportunity to do something we as a team love – making robotic vehicles and putting the NetBurner products through some punishing field testing! A big shout out to SparkFun for making this their 9th annual event – its concentrated awesome on many levels.
As with any side-project, especially with a hard and fast deadline, loose-ends were just an inevitability. When I left for Denver on Thursday afternoon I had three software bits unfinished. I’d done testing and analysis on all three, but these were still incomplete:
After a harrowing but somewhat successful first day of racing at the SparkFun VC 2017 I needed to regroup and literally do some hacking. I spent the afternoon cannibalizing some aluminum angle from one of the people working on the manned AVC car. I hacksawed off a chunk, drilled and tapped here and there, added some strategic zip-ties and repaired the broken bracket that was badly damaged in a collision earlier that day on the white car. In general, the build and wiring quality of the white car was better than for the black Car (I built the black car first). This left me feeling pretty good about Sunday and I went out for a pre-race dinner with my wife and my sisters-in-law. (One flew out with us, and the other lives near Denver).
