In “openHAB RGB LED Light Cube with WS2812B and NXP Kinetis” I started experimenting Kinetis boards, a LED cube diffuser and Adafruit WS2812B NeoPixel LEDs. That worked well, but I was not to very happy about the visual effect. So here is my next version: I wanted to have control over each side of the cube. For this I have built a cube inside the cube with a 3D printed structure:
In “Blinky LED with openHAB on Raspberry Pi” I have used openHAB on a Raspberry Pi to control an LED attached to the Pi, and in “Controlling NXP Freedom Board RGB LED with openHAB and Raspberry Pi” I have explored how to connect a NXP Freedom Board over USB CDC to the Raspberry Pi. In this article I’m going to combine both: to control the LED on a NXP Freedom board remotely with openHAB on the Raspberry Pi.
Hi again to all the amazing readers of this blog! Well guess what, I am still stuck with the programming code of my NeoMatrix Demo. I think it all started with a bad choice of importing the program and libraries from the mbed to KDS. 😦
You can refer to https://mbed.org/ for other programs if you guys want to try.
Well in my last blog I told you about importing the projects and then building them. Well that was what I was trying to do but it turns out that it is not a good idea. I still have a compilation error which is there probably because of a missing assembly. Debugging the code can sometimes be really frustrating for me. 😐 So, I have decided to start from the scratch and write the code in Kinetis Design studio with the help of the Kinetis SDK. There is already the gpio example for FRDM-K64F available under the driver examples folder in KSDK_1.2.0
I believe waiting makes you feel more impatient. So here I am, waiting for my NeoMatrix 8×8 – 64 RGB LED Pixel Matrix to arrive, so that we can begin working on our cool project. But looking on the brighter side, I got some time to make the beforehand preparations for our Signboard project. I took the opportunity to invest this time in finding out how to start running the Adafruit NeoMatrix with Kinetis FRDM-K64F development board. We should definitely get ourselves ready with something so that we can test NeoMatrix with FRDM-K64F as it arrives. So I thought of setting up a repository where we can turn back anytime we feel we are stuck.
