No interrupts, > no VS supply? Datasheet disagrees. In my case the T_CRIT_A and INT are not connected on the schematic. Moreover, the V+ is connected to board's 3V3. Hence, the conclusion that this sensor works as "simple" I2C based temperature sensor. > > Best regards, > Krzysztof > -- Best regards, Lukasz Majewski -- Nabla Software Engineering GmbH HRB 40522 Augsburg Phone: +49 821 45592596 E-Mail: office@nabladev.com Managing Director : Stefano Babic
