2011-08-23write(), print(), and println() now return number of bytes written.David A. Mellis
The type is long, and negative values indicate errors. Needs more testing. http://code.google.com/p/arduino/issues/detail?id=551
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
2011-05-12Small optimization in HardwareSerial.David A. Mellis
begin(long) -> begin(unsigned long) Conflicts: hardware/arduino/cores/arduino/HardwareSerial.h
2011-05-07Adding serialEvent(), serialEvent1(), etc.David A. Mellis
Called from within the serial receive interrupt. These are implemented as an empty weak function in the core that be overridden by the user's sketch. http://code.google.com/p/arduino/issues/detail?id=263
2011-05-07Refactoring the UART0 / USART0 receive interrupt handler.David A. Mellis
2011-05-07Changing Serial.flush() to write outgoing data, not drop incoming data.David A. Mellis
This brings it in line with most other uses of flush(), both in and out of Arduino. http://code.google.com/p/arduino/issues/detail?id=497
2011-03-06Flushing outgoing and incoming data in Serial.end().David A. Mellis
That is, waiting for outgoing data to transmit and dropping any received data.
2011-03-06Fixing race condition in Serial write (Brian Cook).David A. Mellis
2011-03-05Implemented serial transmit buffering.David A. Mellis
Now Serial.write() places characters in the transmit buffer, and the data register empty interrupt reads and transmit them. Based loosely on the implementation here: ftp://wookey.org.uk/arduino. http://code.google.com/p/arduino/issues/detail?id=262
2011-03-01Moving wiring.h contents into Arduino.h.David A. Mellis
2010-11-11Cast to encourage optimization of Serial ring buffer index calculations.David A. Mellis
http://code.google.com/p/arduino/issues/detail?id=391
2010-11-11Changing baud rate calculation to always use double speed mode except for ↵David A. Mellis
57600 baud at 16 MHz. http://code.google.com/p/arduino/issues/detail?id=394
2010-10-17Making HardwareSerial tests register-based, not CPU-based.David A. Mellis
Mark Sproul's patches, via Christian Maglie. http://code.google.com/p/arduino/issues/detail?id=315
2010-09-081280 -> 1280/2560.David A. Mellis
2010-08-02changing available() to return an int (because the Ethernet Client class or ↵David A. Mellis
another stream might need more than 255 bytes).
2010-07-04Adding a peek() function to Stream and HardwareSerial (Serial).David A. Mellis
2010-07-04Adding support for printing Strings to the Print class.David A. Mellis
2009-12-23Adding Serial.end().David A. Mellis
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.
2009-11-07Moving things around.David A. Mellis
2009-07-12Adding improved baud rate calculation, including use (or not) of the U2X ↵David A. Mellis
bit. (Code from gabebear).
2009-07-12Clearing the U2Xn bit in Serial.begin() (because it is set on the Pro / Pro ↵David A. Mellis
Mini 328). Fixing some indentation.
2009-06-01First integration of the Arduino code in Processing 5503: PreProcessor and ↵David A. Mellis
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).
