Arduino 1.5.6 BETA

Changelog

IDE

• Implemented 1.5 library specification Rev.2
  (https://github.com/arduino/Arduino/wiki/Arduino-IDE-1.5:-Library-specification)
• Replaced RXTX library with JSSC (Alexey Sokolov)
  http://code.google.com/p/java-simple-serial-connector/
• If two libraries provides the same .h file prioritize the library with tha same folder name
• Improved command-line parsing (Matthijs Kooijman)
• Windows: added arduino_debug.exe to help debugging errors when launch4j fails to start IDE

Librarires

• TFT: warning messages in PImage class and strings inside examples now stored in flash to save RAM.
• Ethernet: added operator == for EthernetClient class (Norbert Truchsess)
• Robot_Control: removed embedded copies of Wire and SPI to allow their use in sketch.
  Old sketches using Robot_Control now must include Wire.h and SPI.h.
• Robot_Control: fixed issues about motor turning algorithm
• Bridge: optimized FileIO.doBuffer() (bobh66)

Core

• avr: Pile of HardwareSerial improvements (Matthijs Kooijman)
  • Remove duplicate code from HardwareSerial::begin() methods
  • Simplify HardwareSerial::begin() (Rob Tillaart)
  • Use constants for register bit positions in HardwareSerial
  • Fix HardwareSerial::flush() when interrupts are kept disabled for a while
  • Fix lockup when writing to HardwareSerial with interrupts disabled
  • Disable the UDRE interrupt sooner in HardwareSerial (Nathan Blackwell)
  • Put each HardwareSerial instance in its own .cpp file in order to save memory
    for unused UARTS
  • In HardwareSerial::write, bypass the queue when it's empty in order to
    improve throughput when using high baudrates (KurtE)
• sam: Fixed wrap-around bug in delay() (Mark Tillotson)
• sam: Fixed regression in analogRead() (fails to read multiple channels) (Mark Tillotson)
• sam: Fixed loops in Reset.cpp (Matthijs Kooijman)
• sam: Optimized delayMicroseconds() (Rob Tillaart) #1121
• sam: added itoa() and related functions
• Optimized Print::print(String&) method, now uses internal string buffer to perform block write
• Improved portability of String class (maniacbug) #695
• Make some operators in IPAddress const (Matthijs Kooijman)
• Fix for compiling assembler files with newer gcc
