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.
With the oscilloscope, I tried to time the signals but could not do it in a better way. I will be working on it later this summer and probably through the fall, because the good news is that I can stay with Freescale for next fall as well.
Working on this project helped me a lot for working on another project for competitive analysis of Freescale with other semiconductor companies. I am actually able to analyze the DMA (Direct Memory Access), EDMA, FTM (Flex Time Modules) concepts and get my hands on them. This really helps if you want to compare the features with other microcontrollers. I think MCU on Eclipse is the great platform by Erich for all the tech savvy people around the world to get some practical experience of the Microcontroller boards by Freescale.
In my next blog, I will be trying to come up with the right signals so as to light up the board as required. After that I will be working on taking this project further as I talked about the signboard.
