    Hello Roy,

    To change the resolution of the device, you will need to change bit D5 and D6 with the Configuration Register. R1 and R0 should be changed to a 1. Can you provide a communication log of how you are writing to TMP175-Q1? This will help me further debug your issue.

    Best Regards,
