Melexis SMBus IR Thermometer - NFI

hello,

i have tried the codes too, but no output appear at all. i think it is stuck in the i2cmaster. even the printf doesnt work at all but when i remove the i2cmaster.h and comment out the unnecessary codes-left only the prints--it works. so i believe it is caaused by the i2cmaster.h

anybody could help?
i guess every1 is having the same problems too

thank you
