Fahrenheit not displaying properly in temp bar #25

Closed JSField closed 6 years ago

JSField commented 6 years ago

I have a Lepton 3 with the spot sensor, firmware v2.44, and when I turn on the unit in °F mode, after the warmup, the numbers in the bar are wrong. They go from low negative numbers to extremely high positive numbers. If I change to °C, the numbers are still wrong, until I reboot the camera, then they are ok. If I switch to °F, the bar numbers are OK, unless I try to use Manual, try to adjust the min or max, the + and - buttons change the values by large steps. Something appears to be wrong with °F conversion.

Heres what it looks like when in °F mode:

Thanks for the observation.

There was indeed a mistake in the fahrenheit conversion, that caused the mentioned bugs. It's fixed now and will be implemented in the next FW release.

Should be fixed in FW version 2.46. If not, please reopen this issue.
