From 6b2700e2b1a03b7e0191f3dd9b34f8c51eea3c84 Mon Sep 17 00:00:00 2001 From: Aditya Gaddam Date: Fri, 31 Aug 2012 14:19:57 -0400 Subject: "Added ability to set callbacks for interrupts that get an argument. This argument can be the instance that needs to handle the interrupt, or just a random argument you might find useful later. Suggestions from mbolivar and iperry from pull53 on libmaple were taken into account.

We can probably use voidFuncPtr instead, but this way people can see that the function expects something different. Existing functions haven't changed in signature.
