Readout temperature from lpGBT #305
Description
Is your feature request related to a problem? Please describe.
The lpGBTs have an ability to read out temperature as a function of ADCs. We should find a way to grab that temperature and print it out for users.
Describe the solution you'd like
I will figure out how to:
- read lpGBT chip id
- fetch per-chip calibration constants
- perform a live measurement to determine the optimal ADC voltage reference
- output a yaml file containing the chip ids and voltage references
- apply the constants and voltage references
- find the most accurate ADC operating point
- convert final ADC reading to Celsius
Describe alternatives you've considered
If I cannot do the above then I can probably read out ADCs alone to get a sort of idea of temperature fluctuations but it would only be good for seeing that there has been a change.
Additional context
Below are some slides from @cmantill's student Gabi Hamilton that I will use as reference.
