Hi,
 
After I add the 4.7Kohm external pull up resistors on the SCL and SDA lines, I would like to use the AVR Butterfly (US$19.95, temperature sensor, same external flash as the Mica2, sounder, 5-way joystick, light sensor, and a 6 position scrollable alpha-numeric LCD display) as a user interface for my Mica2's. I can write the slave I2C routines for the ATmega169 in regular avr-gcc, but haven't been able to find any TinyOS examples of Mica's using I2C in the master mode to talk with other uP enabled devices. Is the Omnisound board communicating over I2C?       Thanks
 
Richard
