This winter in the Alps is very dry and warm. Because there is no snow it is excellent to do some hiking instead. I’m closing the year with the family in the Italian part of the Alps, and we visited today the Fane Alm, a seasonal alpine pasture. The most beautiful small alpine village I ever have seen. It is located at the top end of the valley of Vals, South Tyrol, Italy.
For my home automation project with openHAB I want to attach Freescale (now NXP) FRDM (Freedom) boards so they can take care about the realtime aspects and to act as gateways to my other systems. One way is to use USB CDC (Serial over USB) as communication channel. USB has the advantage that it powers the board, plus I can attach multiple devices: up to four on the Raspberry Pi 2 and even more with using a USB hub. In a standard configuration with a USB WiFi and a USB HID (mouse plus keyboard) dongle I still can attach two Freescale (ahem, NXP) Freedom boards to the Raspberry Pi:
Low and Slow as they say in Texas. This year I wanted to finish the BBQ Smoker season with something special: a BBQ Smoked Veal Brisket 🙂
In my earlier post I showed how I have installed the open source openHAB home automation system (see “Installing openHAB Home Automation on Raspberry Pi“). In this post I show how to control a local LED on the Raspberry Pi with openHAB home automation system: how to control any GPIO pin on the Raspberry Pi from remote:
In “Installing openHAB Home Automation on Raspberry Pi” I have set up openHAB on a Raspberry Pi 2. But when I reboot it, I need to start openHAB manually. This post is about how to start openHAB automatically after a reboot.
I’m currently building a home automation project around Raspberry Pi: I want to be able to monitor and control things like the lights, garage doors and the heating system both at home and from remote. I already have added a touch screen to one of my Raspberry Pi 2 computers (see “Adding a Touch LCD to the Raspberry Pi 2“). This article is about how to install the openHAB on that Raspberry so it can be the brain of the automation system.
Question: What is the IP address of my Raspberry Pi?
The Winter Solstice day ended with a spectacular sunset sky:
Happy Solsticing 🙂
I use my Raspberry Pi’s usually with an external VGA or HDMI monitor. How cool would it be to use a touch LCD screen instead?
The shortest day of the year started with a beautiful sunrise. Good morning everyone!
Happy Raising 🙂
For years a coworker is using a BBQ smoker to prepare a turkey for Silvester dinner. After hearing him so many times about how excellent this is, time to try this out myself. I cannot wait for the year-end, so I have put a full size turkey into my smoker today 🙂
For a space project we have to make sure that things are not failing while our hardware orbits around the Mother Earth. Therefore we are using different static and dynamic analysis tools, and one of it is using PC-lint from Gimpel to catch as many errors and bugs as possible. For that project, we are using Eclipse with the GNU ARM Embedded (launchpad) ARM compiler and Eclipse as IDE with the GNU ARM Eclipse plugins. There are commercial plugins available for linting with Eclipse (e.g. Linticator), but with a few tweaks it is possible to lint with Eclipse free-of-charge. So this article is about how to lint an Eclipse (Freescale/NXP Kinetis Design Studio) project with PC-Lint.
My Raspberry Pi Zero arrived last week (see “A Raspberry Pi for $5! What are your decision factors?“), and finally I have found an hour to try it out. Because the ‘bare board’ $5 version was sold out at that time, I ordered a package with 8GB SD card, micro USB cable and mini HDMI adapter. That way I had all the needed cables, including the mini HDMI adapter cable:
Dealing with a nasty flu, so I did not sleep very well. The updside of that is that I woke up early to see this beautiful sunrise over the Alps, with trails from airplanes high above….
I hope I can fully recover over the weekend.
Happy Trailing 🙂
“If you have knowledge, let others light their candles in it.”
I very much like that one from Margaret Fuller because this does not apply to all of us working in the education industry: so many engineers have so much knowledge, but do not share it, as if they are afraid that they will lose something? Sharing knowledge is an excellent way to increase your own knowledge too.
This tutorial describes how to create a Kinetis SDK V1.3 project using the Freescale project generator in Kinetis Design Studio.
“If you are in a hurry, go slowly.”
Konfuzius, I hear you. But so hard to follow that advice. Simply too much going on right now. But I’ll give it a try….
