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:
Segger System View for FreeRTOS
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:
Test Setup
This tutorial is about how to create a lwIP project with FreeRTOS using the Kinetis SDK V1.3.0 with Kinetis Design Studio on the Freescale FRDM-K64F board.

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.

How about to use the Freescale FRDM-KL43Z board (see “Unboxing the Freescale FRDM-KL43Z Board“) to play a Tetris game?
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:

Probably for cost reasons, the Freescale FRDM-K22F does not come with the micro SD card socket populated on the the board:

With a little soldering skills it is possible to populate the socket so the board can be used with a file system on it :-):

I don’t own a Mac computer, and I try to keep my tutorials as multi-host-platform as possible. So it is always cool to see if someone else posts a nice tutorial on a different host machine: For all Mac (and as well non Mac) users, have a look at this tutorial Nash Reilly has posted: “An Introduction to Freescale’s Kinetis Design Studio.”
It nicely explains downloading and installing KDS with the Kinetis SDK and then run a ‘hello world’ program on the hardware.
And very worthwhile to check out Nash’s other articles here too: http://www.allaboutcircuits.com/author/nash-reilly
Happy Nashing 🙂
In “Kinetis Drone: Frame Construction with Graupner Race Copter Alpha 250 Q” I have assembled the frame for my Kinetis Drone. In this post I’m going to drive the ESC’s (Electronic Speed Controllers) with the Freescale FRDM-K22F board:
