Before, HardwareSerial1+.cpp were a copy of HardwareSerial1.cpp with all 0's replaced by the corresponding number. This would mean that e.g. the Serial1 object would use the UBRRL register instead of UBRR1L when it was defined, or the USART_RX_vect instead of USART1_RX_vect. In practice, this would neve actually cause problems, since: - No avr chip currently has both the non-numbered registers as well as numbered registers. - HardwareSerial.h would only define HAVE_HWSERIALx when the corresponding numbered register is defined (except for HAVE_HWSERIAL0, which is also defined when the unnumbered registers are present). Furthermore, before both the UARTx_xx_vect and USART_x_xx_vect was used. Looking at the include files, only UART1_xx_vect is actually used (by iom161.h), the others use USARTx_xx_vect. For this reason, HardwareSerial1.cpp keeps the preprocessor conditional to select either UART or USART and the other files use USART unconditionally. While we're here, also fix the compiler error message when no valid ISR name was found (it previously said "for the first UART" in all cases).
Arduino
-
Arduino is an open-source physical computing platform based on a simple i/o board and a development environment that implements the Processing/Wiring language. Arduino can be used to develop stand-alone interactive objects or can be connected to software on your computer (e.g. Flash, Processing, MaxMSP). The boards can be assembled by hand or purchased preassembled; the open-source IDE can be downloaded for free.

To report a bug in the software or to request a simple enhancement go to: http://github.com/arduino/Arduino/issues
-
More complex requests and technical discussion should go on the Arduino Developers mailing list: https://groups.google.com/a/arduino.cc/forum/#!forum/developers
-
If you're interested in modifying or extending the Arduino software, we strongly suggest discussing your ideas on the Developers mailing list before starting to work on them. That way you can coordinate with the Arduino Team and others, giving your work a higher chance of being integrated into the official release https://groups.google.com/a/arduino.cc/forum/#!forum/developers
Installation
Detailed instructions are in reference/Guide_Windows.html and reference/Guide_MacOSX.html. For Linux, see the Arduino playground: http://www.arduino.cc/playground/Learning/Linux
Credits
Arduino is an open source project, supported by many.
The Arduino team is composed of Massimo Banzi, David Cuartielles, Tom Igoe, Gianluca Martino, Daniela Antonietti, and David A. Mellis.
Arduino uses the GNU avr-gcc toolchain, avrdude, avr-libc, and code from Processing and Wiring.
