HDC1080: HD1080 Not able to Read Temp/Humidity Registers !!

Part Number: HDC1080

Hello  ,

We are using HDC1080 sensor in our design. We are trying to read temperature and humidity values from our i2c master device, We are able to read and write to the configuration(0x02), Manufacturer ID(0xFE) but we are not able to read temperature and humidity register values, while reading the temperature/humidity register value we are not getting ACK from the sensor, We tried both the Device Measurement Configuration(0x3500 and 0x1500) provided in the datasheet. Please find the attached timing captured during the temperature read.

Please let us know !!

Thanks

Antony
