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

An Introduction to Kinetis Design Studio for Mac OS X
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 🙂
Tutorial: Using GNU Profiling (gprof) with ARM Cortex-M
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.

To 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.

Tutorial: Adafruit WS2812B NeoPixels with the Freescale FRDM-K64F Board – Part 5: DMA
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:

Tutorial: Adafruit WS2812B NeoPixels with the Freescale FRDM-K64F Board – Part 4: Timer
This is Part 4 of a Mini Series. In Part 3, I described the software concepts (see “Tutorial: Adafruit WS2812B NeoPixels with the Freescale FRDM-K64F Board – Part 3: Concepts“). In this post I describe how to set-up the timer to trigger later DMA operations. The goal is to drive Adafruit’s NeoPixel (WS2812B) with the Freescale FRDM-K64F board:

Tutorial: Adafruit WS2812B NeoPixels with the Freescale FRDM-K64F Board – Part 3: Concepts
This is Part 3 of a Mini Series. In Part 2, I described how to set up the development tools and to debug the first project (see “Tutorial: Adafruit WS2812B NeoPixels with the Freescale FRDM-K64F Board – Part 2: Software Tools“). Now it is time to look into the software concepts. The goal is to drive Adafruit’s NeoPixel (WS2812B) with the Freescale FRDM-K64F board:

Tutorial: Adafruit WS2812B NeoPixels with the Freescale FRDM-K64F Board – Part 2: Software Tools
This is Part 2 of a Mini Series. In Part 1, I described how to set up the hardware (see “Tutorial: Adafruit WS2812B NeoPixels with the Freescale FRDM-K64F Board – Part 1: Hardware“). Now it is time to have the software tools ready. In this post I describe to have the IDE (Freescale Kinetis Design Studio) with the Freescale SDK installed, along with the correct firmware on the FRDM-K64F Board. The goal is to drive Adafruit’s NeoPixel (WS2812B) with the Freescale FRDM-K64F board:

Tutorial: Adafruit WS2812B NeoPixels with the Freescale FRDM-K64F Board – Part 1: Hardware
This is Part 1 of a Mini Series. Manya has challenged herself to use the Adafruit NeoPixels (WS2812B RBG LEDs) with the Freescale FRDM-K64F board and the Kinetis SDK (see “Let’s play with Freescale FRDM-K64F“). I did a while back that with the FRDM-KL25Z board (see “NeoShield: WS2812 RGB LED Shield with DMA and nRF24L01+“). I used Processor Expert in my project (without the Kinetis SDK), and with this setup it is very easy. However, Manya wanted to do this with the Kinetis SDK and without Processor Expert. No surprise to me, she has found out that this setup with the Kinetis SDK and without the usage of Processor Expert is much more challenging (see “Not done yet!!“). I promised to Manya to give her a helping hand, so here we go! 🙂

To write a program using KDS with Kinetis SDK!!
Starting from the baby steps for our project seems like a good idea but not very helpful though. Learning and understanding Kinetis SDK seems like a lot of work. Meanwhile, I would like to share an important piece of information that I found on my path of working on this project. Many of you might already know, but being a first time user of Kinetis SDK 1.2.0, I found that there are few differences between Kinetis SDK 1.1.0 and Kinetis SDK 1.2.0. I was trying my hands on to use the KDS with KSDK.
So, In order to create a KDS project with Kinetis SDK, I need to create new folders, add different files and the libraries to my project. I didn’t look into all this with much detail before. I would recommend all to go through this link in order to understand using KDS with Kinetis SDK1.1.0 and Kinetis SDK 1.2.0.
This is how it looks after you have added everything:
