Interrupt On change Feature for Port B "Clarification N

[scottc]

Hello, I am using a PIC16F886 for a small project. I notice this part
supports Interrupt On change feature for all pins on Port B

I have a button connected to RB2 and would like to run this using one
of the interrupts. I am Unclear on how to designate RB2 for use as
a interrupt so hopefully someone can clarify.

in .h File for the part at the bottom, there are pin defines and a memory address for each of the IOC features.

#define INT_RB2

So it looks like the pin is defined for the compiler. Would something
like the following code snip be the correct method to use so that the compiler knows that I wish to generate a interrupt on RB2.

---------------------------------------------------------------------------

INT_EXT //<<<<Not sure if this is correct to use
My ISR ()
}
Do something
{

Void Main(void)
{

disable_interrupts(GLOBAL);
enable_interrupts(INT_RB2);
ext_int_edge(H_TO_L);

}

Thanks Guys

The following thread has a demo program for #int_rb on the 16F886:

The program expects push-button switches to be on pins B0, B1, and B2.
The external circuit for each pushbutton should be like this:

Thanks, PCM

That gives me something to work with
