I updated the code of the pHduino to be compatible with the Arudino 1.0. This is the changelog.
v041_20120312
- Removed all WProgram.h and WConstants.h and replaced by Arduino.h.
 - DS1307.cpp: Included Arduino.h.
 - DS1307.cpp: Typecast: from Wire.write(0x00) to Wire.write((uint8_t)0x00).
 - DS1307.h and twi_eeprom.h: Changed all Wire.send to Wire.write and all Wire.receive to Wire.read.
 - acme.h: Change from Serial.print(c,BYTE) to Serial.write(c).
 - Changed the main program .pde to .ino.
 - Changed CL_MAX_PARAMS_NUM in commandline.h from 2 to 3 (fco).
 
Best.
