I am looking to interface a Melexis IR sensor to a AVR micro(ATmega2560). The sensor has an SMBus interface. The datasheet of the micro does not explicitly state that it supports SMBus. But it has a TWI interface which is compatible with I2C.
1. Has anyone achieved this?
2. If yes, what is the maximum frequency of communication
3. Have anyone interfaced the sensor with a different micro which does not explicitly state that they support SMBus?
