* Interrupt and PWM utilities for 16 bit Timer3 on ATmega168/328
|
||
|
|
* Original code by Jesse Tane for http://labs.ideo.com August 2008
|
||
|
|
* Modified March 2009 by Jérôme Despatis and Jesse Tane for ATmega328 support
|
||
|
|
* Modified June 2009 by Michael Polli and Jesse Tane to fix a bug in setPeriod() which caused the timer to stop
