Installing openHAB Home Automation on Raspberry Pi

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.

Linting with Eclipse and the GNU ARM Embedded Launchpad Compiler

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.

Kinetis Drone: Remote Controller with SUMD

The bad news: my ESC (see “Kinetis Drone: Graupner ESC S3055 Failure“) for my Kinetis drone is still not repaired :-(. Anyway, I have plenty of other things to make for my drone project. One is to work on the remote controller:

McuOnEclipse Components: 17-Oct-2015 Release

On SourceForge I have published an update of the McuOnEclipse software components, with following major changes:

  1. FreeRTOS updated to version V8.2.2 which comes with TLS (Thread Local Storage) support and GDB debug helpers.
  2. Percepio Trace updated to V3.0.2 with the release of Segger Real Time Terminal (RTT) for continuous trace streaming.
  3. FSL_USB_Stack with alternate USB initialization to deal with an issue in combination with the Kinetis SDK v1.3.0
  4. GenericI2C and GenericSWI2C have added support for custom I2C bus handling.

Kinetis Drone: Sensor Fusion Toolbox

Flying a quadrocopter without some sensor and microcontroller intelligence will be a challenge. Definitely I will need some intelligent sensor data to help me out :-). Luckily, there is a Freescale ‘Sensor Fusion Toolbox’ and Library which gives me a nice start and visibility into the sensors I plan to use:

Linking additional Object Files with GNU Linker

Sometimes I need to link an object file (e.g. bootloader.o) to my application, and I do not want to build it, or I do not have the sources to build it. There is a simple way with the GNU ARM Eclipse plugins to link extra object files:

Aligning S19 Records to 64-bit Boundaries

Many tool chains and linker are able to produce S19 files, such as with the GNU tools it is the ‘objcopy‘ which does this job (see “Binary (and S19) Files for the mbed Bootloader with Eclipse and GNU ARM Eclipse Plugins“). But these tools usually cannot handle the special cases. For example on the Freescale Kinetis K64F my serial bootloader (see “Serial Bootloader for the Freedom Board with Processor Expert“) had a problem with these lines in the S19 file:

Not aligned S19 file entries
