3D Printed Adafruit NeoPixel LED Frames

I’m experimenting with different 3D printed LED frames printed with ABS (see “Avoid Warping ABS on Ultimaker 2“). I frame multiple Adadfruit 8×8 NeoPixel WS2812B LED modules with 3D printed diffuser and frames to create color effects:

Thanks to Erich and FRDM-K64F!! :)

It has been a long time since I wrote my last blog. I really want to apologize to you all for the delay, but I was busy with another project about the competitive analysis of Freescale with our competitors. I hope I can provide you guys later with some important findings from my research.

Well as far as my project for neopixels using FRDM-K64F is concerned, Erich wrote the wonderful tutorial for all of us to turn on the NeoMatrix. I tried my hands on that and I was indeed able to turn on the board but not in the way I wanted it to. 😦 So, it turns out that I got few LEDs turning blue or some turning green. I asked Erich about it and I got to know that it is because I screwed up with the timing signals. I was using an oscilloscope and not a logic analyzer but Erich’s recommendation was to use the Logic Analyzer. This was the result of my experiment following Erich’s tutorials.

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: https://community.freescale.com/docs/DOC-103288

This is how it looks after you have added everything:
