PostPosted: Mon Jan 26, 2009 2:34 pm     Reply with quote

hello,

Can someone help me ? I'm trying to do a program for explorer 16.
I'm using the 4 buttons of the board. Can I generate an interruption when a button is pressed ?

The buttons are connected to CN change notification.

1. Tell us what PIC you're using.

2. Tell us what model of the Explorer 16 board you are using. There
are at least 3 different models. See this page:

Three of the switches go to "CN" input pins on the PIC24FJ128GA010.
So you could use the "Change Notification" interrupt to detect a keypress.

Unfortunately, I can't help you any more on this because I don't have the
PCD compiler.
