I've read through most everything I can find on getting the 90614 to talk with Arduinos. This thread (http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1214872633/all
) on the older forum had lot of useful information, and it seems many folks have succeeded with this device. I'm not so lucky. My setup is a 3v3 8MHz Mini Pro connected to the MLX90614 as advised. I've installed the I2C Master library and modified the clock rate in the twimaster.cpp file (tried both 16 and 8 MHz). I2C clock rate is set to 50KHz.
I've tried the sketches from Dave Eaton, Bildr and Narwath. All compile and upload, all result in same outcome: I get no output whatsoever from the serial port, not even the "Hello" println that's only preceded by the i2c library include and the serial rate. Nothing.
Strangely, the onboard led on pin 13 lights up shortly after reset and stays on solid. I can't find code anywhere in the library or sketches that would explain this.
Any thoughts would be appreciated. Is it possible that 50KHz is too fast for the 8 MHz Mini?
