2015-09-28Removed Timer warnings when Timer 2 is not presentNico
2015-07-03Removed a handful of SVN expansion keywords. See #277Federico Fissore
2015-05-22Indent fix.Cristian Maglie
2015-05-22zero delay fix, ADC prescaler fixCano
2015-05-22delayMicroseconds(): added support for 1Mhz, 12Mhz and 24MhzCano
1Mhz is a default clock speed on Atmega328, many users run it on the internal 1Mhz clock to save battery power. Up until now delayMicroseconds() function wasn't taking this frequencies into an account.

2012-11-02Added general yield()-hook for cooperative scheduling development (part 2)Cristian Maglie
2012-04-19bugfix for configuring PWM on D6 and D13 too early. (thanks to Limor Fried)Zach Eveland
was starting PWM on these pins too soon - in init() instead of when analogWrite() was called. as a result doing output on port registers directly failed.
2011-12-18fixed digitalWrite on timer 4 pins (D6 and D13)Zach Eveland
2011-12-11fixed TIMER4 use on LeonardoZach Eveland
ATMEGA32U4 has major differences in TIMER4 registers compared to ATMEGA1280 and 2560. turnOffPWM, analogWrite, and initialize routines had wrong registers, bit names, etc.

2009-11-21Improving third-party hardware support:David A. Mellis
- moving back to multple cores per platform - using target instead of platform - moving per-board and per-programmer preferences out of Preferences.java and into a new Target class - adding a new "target" preference - support for platform:value values in board preferences for bootloader path and core - XXX: need to support platform:value syntax for board upload.using preferences.

2009-05-12Optimizing the timer0 overflow handler (for millis()), based on work by ↵David A. Mellis
WestFW and help from mikalhart. Increasing precision of math constants.

2008-04-18Fixing millis() overflow: changing millis() and the timer 0 overflow handler ↵David A. Mellis
so that the millis count is updated in the interrupt, and so we don't need to do a conversion inside millis(). Updated to do list.
