I'm an idiot and I don't know why! - CCP1_INT

[Cobra_Phil]

I've been learning about interrupts thanks to the fabulous work of Darrel. I've been able to get INT_INT, RX_INT, and RBC_INT working with no problems. But I can't figure out how to get CCP1_INT working. I've looked at others examples and still I am missing something. Will someone please show me how big of an idiot I really am?
I've tried different configuration with TMR1...starting it, stopping it, leaving it out altogether with no luck.

It doesn't get much easier than this....

What is triggering the interrupt on RB3?

[Cobra_Phil]

pushbutton

[Bruce]

RB3 CCP1 input is an ST type, so it needs 0.8 * Vdd to meet the logic 1 input threshold.

I can't really tell from your schematic, but it looks like you might have a voltage divider?

5.00v on Pin3

Hmm ... should work. I just tested it with the older version of DT_INTS-14 & ReEnterPBP.

Are you using the latest version? I haven't tried the newer rev yet.
