* Interrupt and PWM utilities for 16 bit Timer1 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 |
|
* Modified Oct 2009 by Dan Clemens to work with timer1 of the ATMega1280 or Arduino Mega |
|
* Modified April 2012 by Paul Stoffregen |
|
* Modified again, June 2014 by Paul Stoffregen |
|
* This version has been downloaded from https://github.com/PaulStoffregen/TimerOne (commit aaeb4a36f5f23e99e6011bea77cf76abb912e13a) |
