2015-09-18Fixed wrong condition in turnOffPWM(..)Cristian Maglie
Fix #2163
2015-07-03Removed a handful of SVN expansion keywords. See #277Federico Fissore
2014-05-16Support TIMER1CMatthijs Kooijman
Some devices, such as the atmega2560 or the atmega256rfr2 have a timer1c output. It seems this output is not connected to anything on the Arduino Mega, but this allows using it on third party hardware nonetheless.
2012-01-10Merge branch 'master' of github.com:arduino/Arduino into new-extensionZach Eveland
2012-01-02Adding INPUT_PULLUP option pinMode(). (Paul Stoffregen).David A. Mellis
This also changes pinMode(pin, INPUT); to explicitly disable the pull-up resistor, even if it was previously set. http://code.google.com/p/arduino/issues/detail?id=246
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.

2011-03-03Removing optimized digitalWrite(), digitalRead(), pinMode().David A. Mellis
2011-02-18Revert "Changes to optimized digitalWrte(), etc."David A. Mellis
This reverts commit aa1f1cbda9d6bb52785f98b40746920853d6579b.
2011-02-18Revert "Adding noAnalogWrite() function to disable PWM."David A. Mellis
This reverts commit 38d4a34fec6925b29a732d13e200f54ee4b42025.
2011-02-12Adding noAnalogWrite() function to disable PWM.David A. Mellis
Also, removing the inline version of digitalPinToTimer() (since we're not optimizing the functions that use it anyway). The noAnalogWrite() function is in wiring_analog.c, deriving from the previous turnOffPWM() which has moved from wiring_digital.c. http://code.google.com/p/arduino/issues/detail?id=476
2011-02-11Changes to optimized digitalWrte(), etc.David A. Mellis
Factoring out the implementation of digitalWrite(), digitalRead(), and pinMode() into macros that can either be inlined (for constant pin numbers) or executed within a function (non-constant pins). Removing testing for timers on pins in digitalWrite(), digitalRead(), and pinMode(). Moving pin to port macros from pins_arduino.h to wiring.h.

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.
