Testing external interrupt in TWR-K60D100M

Question asked by O M on Jul 18, 2013

Hello

 

I added ExtInt component and I want to check that it is working.

I thought to use the touch sensing inputs (the 4 touch "pads" that also "use as" a LED (blue, gree, orange, yellow)

 

In the schematics of the board I saw it is connected to pins PTB16, PTB2, PTB3, PTA4.

Am I right ?

 

From some reason, the Processor Expert doesn't allow me to choose those pins for my ExtInt.

What to do ?

 

(I saw that for K40, there is example for it, but it looks very "heavy" for a simple input test)

 

Thanks a lot

OM
