Toggle LED using a push button and FRDM-K64F?

dayakannan — Wed, 08 Apr 2015 11:56:13 GMT

Hi.

I decided to venture into embedded systems very recently and enthusiastically got a new K64F board. I was able to manage a Blinky using youtube tutorials - but I don't understand what's happening behind the scenes, so to speak (please excuse my non-technical usage of words, I'm very new).

I now want to write a program to toggle an LED using a push button. I have been searching all over the internet for tutorials that can help me figure out what to do and how to do it but haven't found anything yet.

Could anybody please help me with this? I would like to know where to find more information about the board I have and where to go online to start experimenting with this.

Thank you :smileyhappy:

I have a tutorial for the FRDM-KL25Z here:

As that board shares the button with the reset function of the board, simply ignore the part about the reset line :-)

See http://www.utasker.com/kinetis/FRDM-K64F.html

You can toggle using push buttons on the board or buttons on a web page using a web browser.

Tutorial at http://www.utasker.com/docs/KINETIS/uTaskerV1.4_Kinetis.pdf

Simulate your board and the K64 in real-time with VisualStudio to learn all internal workings (including peripherals, interrupts, DMA and memory operations).
