That was nice of you to do that Joe.

I think Darrel may have fixed that in his new version of interrupts. It is v1.00. You can find it at the bottom of this page:

It says it has GPC_INT -- GPIO Int On Change , among a bunch of other additions. But I have not played much with the DT-INTS-14 ... yet.
