e1fdc86e40 ctrl_panel: Keep i_set visible when PID engaged 
Since i_set is also plotted, we would also want to see its precise value
too.

89b908fab1 ctrl_panel: Remove MutexParameter 
Use the standard ListParamenter instead, and hook up UI changes
elsewhere.

a1c260d52e ctrl_panel: Limits fixes 
* PID Autotune test current should be positive

* Maximum absolute voltage should be 4 V not 5 V
 2024-07-19 14:50:06 +08:00
atse
d76e015893 ctrl_panel: Code cleanup 
* Remove unnecessary duplication of `THERMOSTAT_PARAMETERS`

* i -> ch

* Separate ParameterTree and Parameter initiation

* Remove extra "channel" option to root parameters, as the "value"
option is already the channel number

39018d2360 ctrl_panel: Stop crushing spinboxes 
It might not be the case on some themes, but on the default Qt theme the
spinbox are a bit too short for the containing numbers. See
https://github.com/pyqtgraph/pyqtgraph/issues/701.

25c7a070d9 ctrl_panel: Approriate units for measured current 
Allow the readonly display of current to vary its SI prefix in the unit,
since as a display entry it won't have the unit adjustment problem.
