For next semester I plan to use the tinyK20 as a remote controller for the Zumo Robots. I already had an early prototype presented in “3D Printed Gameboy and Remote Controller with tinyK20 Board“, so here is the next iteration of, in a sneak preview:
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.
