2012-08-30Changing setting of the UMSELn bits (for UART mode) and serial config values.David A. Mellis
Before, the UMSELn1 bit was being to set to 1, putting the UART into a reserved mode. Now, we only set the high (0x80) bit to 1 for the ATmega8, which is needed to access UCSRnC (whose i/o address is shared with UBRRH). Also, no longer bitwise-or the new config with the existing register value, because we're actually configuring all the settings in the register. (We're not using UCPOL, but it's supposed to be 0 in asynchronous mode.)

2012-04-01added Boolean operators to HardwareSerial and CDC to test whether the port ↵Zach Eveland
is ready to send data. Mostly useful for Leonardo - simple way to test whether the port is actually opened by an application and ready to receive data. For Serial objects attached to real UARTs always returns true.

2011-08-26Moving write errors out of return value into separate API methods.David A. Mellis
write(), print(), println() now return size_t (and don't use negative values to signal errors). Print adds writeError() for checking for write errors, clearWriteError() to reset the flag to false, and a protected setWriteError() for signalling errors. http://code.google.com/p/arduino/issues/detail?id=598

2011-05-20Fixing 300 baud communication for serial.David A. Mellis
Because UBBR is only 12 bits, we were overflowing it at 300 baud because of the use of the U2X bit. Now we turn off U2X if it would yield a UBBR value that would overflow. Note that this breaks 300 baud communication with the computer on the Uno and Mega 2560 because the 8U2 USB-serial firmware has this same bug (and previously they cancelled each other out). Since, however, it seems more likely that people will need to use 300 baud to communicate with other (legacy) hardware than with the computer, I'm making this change. Issue for 8U2 firmware bug: http://code.google.com/p/arduino/issues/detail?id=542 http://code.google.com/p/arduino/issues/detail?id=522

Compiler have been integrated with changes to the Sketch. Compilation still has problems (Thread error on success, and can't handle non-pde files in a sketch). Modified the Mac OS X make.sh to copy the hardware, avr tools, and example over. Removing some of the antlr stuff. Disabling the Commander (command-line execution) for now. Added Library, LibraryManager, and Target. Added support for prefixed preferences (e.g. for boards and programmers).
