First integration of the Arduino code in Processing 5503: PreProcessor and 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).

+// Wire Master Reader
+// by Nicholas Zambetti <http://www.zambetti.com>
+
+// Demonstrates use of the Wire library
+// Reads data from an I2C/TWI slave device
+// Refer to the "Wire Slave Sender" example for use with this
+
+// Created 29 March 2006
+
+#include <Wire.h>
+
+void setup()
+{
+ Wire.begin(); // join i2c bus (address optional for master)
+ Serial.begin(9600); // start serial for output
+}
+
+void loop()
+{
+ Wire.requestFrom(2, 6); // request 6 bytes from slave device #2
+
+ while(Wire.available()) // slave may send less than requested
+ {
+ char c = Wire.receive(); // receive a byte as character
+ Serial.print(c); // print the character
+ }
