how i can toggle led using external interrupt ?

mesdouaabderraz — Tue, 04 Jul 2017 10:08:25 GMT

using the FRDM-K82F kit, I take the example available about input interrupt. in the following path in my K82F’s SDK Folder:

"SDK_2.2_FRDM-K82F.zip\boards\frdmk82f\driver_examples\gpio\input_interrupt".

But I can not connect my external button (Not the button available on the kit) . I do not know if I was wrong on the pine where I must plug the button (i used PORTA1). Or else I skipped a step in my code Which you will find enclosed.

Please if anyone can help me, by Specifying the steps required for programming, Or he has an example of code withe toggle pine.

It is for an urgent project,

Thank you for replying quickly please.

You just need to modify the code refer the image shown below:

But you need to notice the PTA1 is connect to FXOS8700CQ. And this pin is default as JTAG_TDI function.
