From edff1655fe4f3dd27645a9acd846576e75e4ad72 Mon Sep 17 00:00:00 2001 From: Gabe Black Date: Tue, 24 Sep 2013 01:40:07 -0700 Subject: beaglebone: Add code to set the value of the LEDs The LEDs on the beaglebone are connected to GPIOs called USR0-USR3. This change adds some functions to make it easy to set their value and clear what the calling code is trying to do.
