Hello, I have just realized that there have already been an attempt to get 12-bit support into the LM75 driver: http://marc.info/?t=120836918500008&r=1&w=4 But it's not obvious too me why it was finally abandoned. In the GIT log I just find: - More careful initialization. Chips are put into 9-bit mode so the current interconversion routines will never fail. What have I missed? Thanks, Wolfgang.
