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:

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

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.

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

How about to use the Freescale FRDM-KL43Z board (see “Unboxing the Freescale FRDM-KL43Z Board“) to play a Tetris game?
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 🙂
I have published a Sneak Preview how GNU gprof profiling looks for an embedded target ARM Cortex-M in an earlier post:
This tutorial explains how to profile an embedded application (no RTOS needed) on ARM Cortex-M devices with GNU gprof. Additionally I explain the inner workings to generate the data necessary for gprof.
Continue readingTo build an application for a modern microcontroller today is not a simple thing. Well, it depends what ‘simple’ means. But compared to the ‘old days of 8bit micro controllers’ (which are still in use!) developing for a complex 32bit device is definitely a different thing. Not only the complexity has changed, but as well the breath of tools and helpers. In my view, the only constant is ‘change’, and I have changed the way how to develop several times in my career. In this post I present several different techniques I’m using in my development.

This is Part 5 of a Mini Series. In Part 4, I described how to set up the FTM (Kinetis Flex Timer Module) to generate the required waveforms used for DMA operations (see “Tutorial: Adafruit WS2812B NeoPixels with the Freescale FRDM-K64F Board – Part 4: Timer“). In this post I describe how to use to trigger DMA (Direct To Memory) events. The goal is to drive Adafruit’s NeoPixel (WS2812B) with the Freescale FRDM-K64F board:
