It’s not Christmas yet, but: For a research project I’m currently evaluating a new microcontroller where I need a bit more leg room. Right on time I saw that there is a new board available which caught my interest: The Freescale FRDM-K82F :-). Without thinking too much about it, I have ordered that board from Mouser Thursday last week and I had it in my hand today 🙂 Time to put up a quick post about it:

One day earlier than expected, our tinyK20 boards arrived, and they are looking great :-):

One of the most important aspects for developing complex realtime applications is get insights into what is going on the target. Segger just has released a free tool which gives an incredible useful insight view and visualization:

Over the weekend, I finally have repaired the broken ESC (see “Kinetis Drone: Graupner ESC S3055 Failure“). Time to run some first test flights :-).

Time is flying fast, time for another McuOnEclipse components release on SourceForge with the following main changes and features:

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:

In “Overview: From Snippets to Code Generation” I discussed several tools used in my development process. On tool which helps me a lot to get things done is Processor Expert. In this post I’ll give an overview about this tool and reasoning for the pros and cons of using it.

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:

It has been a while since I published my ‘build my own DIY IDE’ (see “DIY Free Toolchain for Kinetis: Part 1 – GNU ARM Build Tools“). I have used that approaches in my classes successfully. Now a new semester is coming up, so time to update the instructions using the latest Eclipse IDE (Mars) and tools (GCC ARM Embedded (launchpad) with GNU ARM Eclipse).

In “Unboxing the Freescale FRDM-KL43Z Board” I was using the FRDM-KL43Z board the first time. The FRDM-KL43Z board has an on-board debug interface (Kinetis K20, OpenSDA). In this post I show how to use the FRDM-KL43Z board to debug another ARM board.
