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.

This is how it looks after you have added everything:

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

How to use Kinetis Design Studio!!

Getting the hands on an embedded project has always been exciting for me. So, here I am again with my blog trying to provide you with an easy to use guide for the Kinetis Design Studio 3.0.0 (KDS_3.0.0). Well, as you all know I am an intern at Freescale working for the first time on KDS, I will tell you what all we can do to start working on it with a perspective of a novice. But personally I feel KDS is one of the most encouraging IDE you can work on. So how do I start with my code for our NeoMatrix board? I am currently working with one of the demo codes for the NeoMatrix:

https://mcuoneclipse.com/2015/07/10/lets-play-with-freescale-frdm-k64f/

So, my first task is to write the code in KDS for the NeoMatrix_Demo. How do I do that? After opening the KDS 3.0.0, I need to go to File and select New and then Kinetis Project. You can see that the New Kinetis Project wizard appears once you click the File>New> Kinetis Project. Type a name and click next.

Learning about Kinetis SDK!!:)

We all know that for an application to develop, for a project to work we need hardware along with the software.  So here we are with our FRDM-K64F development boards, but the question is-how to make them work? I wrote in my second blog about the new getting started process by Freescale for the FRDM-K64F: http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=FRDM-K64F&tab=In-Depth_Tab

This link gives me the opportunity to download the very helpful Kinetis Software Development Kit (SDK) along with the Integrated Development Environment which includes the toolchain Kinetis Design Studio. Let us talk a bit about the Kinetis SDK in this blog. So what does Kinetis SDK is responsible for? In simple terms, it is just software framework which helps us in developing applications across all Kinetis Microcontrollers. It is a package of pre-written code that developers can re-use in order to minimize the amount of unique code that they need to develop themselves.

Getting to know FRDM-K64F and more!! :)

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.

Let’s play with Freescale FRDM-K64F

Hello Again!

In my previous blog I talked about the new getting started process for Kinetis FRDM-K64F development board. Here I am with my next blog going one step further and introducing you to the target application that I have planned for this summer using the awesome FRDM K-64 development board from Freescale. I am planning to work on some really cool stuff that we can do from this board. And I came up with an idea for making an Adafruit NeoPixel NeoMatrix Signboard!!adafruit LED

Wait….does it sound boring to you? Nah… we are not planning some ordinary signboard. This Adafruit NeoPixel NeoMatrix signboard is really cool. It will display what you want to display and it will change the displayed text with just the movement of your hand. Sounds interesting now?? Continue reading →

Hello all!

Here is my second blog about the Kinetis MCU development boards, introducing you to the new and more informative Getting Started process for Kinetis FRDM-K64F from Freescale. As a part of my internship I got the amazing opportunity to play with the ‘New Getting Started’ process and the most recent box of the FRDM-K64F development board from Freescale.

Freescale have been working all along to make the life of its customers easier. So, at the FTF 2015 we launched the new website:

http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=FRDM-K64F&tab=In-Depth_Tab

This website is for the new Getting started process for FRDM K-64F. This website will tell you all that you will need to start the FRDM K-64F development board. Continue reading →

Hello to all the amazing viewers of this fantastic blog! I am Manya Rastogi, a Master’s student at Texas A&M University pursuing Electrical Engineering. This summer, I got a wonderful opportunity to intern at Freescale, as a Technical Product Marketer for the Kinetis Microcontrollers.
Freescale gave me the great chance to attend the Freescale Technology Forum 2015, where I met Erich, a very talented engineer and blogger.  I am really grateful to him for giving me the chance to be his guest blogger.
