Resolution = Precision ? #74

Closed dusscloud closed 4 years ago

dusscloud commented 4 years ago

In order to change sensor resolution, the documentation refers to sensor.set_resolution() (Python case) w1thermsensor --resolution (CLI case)

But it does not work : the rights syntax seems to be sensor.set_precision() (Python case) w1thermsensor --precision (CLI case)

Side note : root is required for such resolution change, I think this may be written in the doc also.

Depending on the version of w1thermsensor that's true.

The precision phrasing was changed to resolution in: https://github.com/timofurrer/w1thermsensor/commit/3e91314dc892e8177011405669f0f3ef254a9146. Because resolution is actually the correct term here.

You can use 1.3.0 from PyPI to have to change. (might be the case that an older version is deployed in rasbian apt sources)

Yes, good catch! I've added this in: https://github.com/timofurrer/w1thermsensor/commit/519010e47e3e7441e05c221e1c6e1cc2f2a83252
