From ff56b76d41a390ed193da180316690f6e2dcbb75 Mon Sep 17 00:00:00 2001 From: Marti Bolivar Date: Sun, 3 Jun 2012 00:02:10 -0400 Subject: STM32F2: Add timer_get_af(). Pull some code out of the F2 pinMode() into a utility function. This feels generally useful enough to be exposed to the users (it will, for example, make it easier to implement input capture in a clean way).
