the specific code:

looking at the firmware interfaces, they appear almost identical.

changes i can identify:

• shaking / locking on HHS
• tb and tc on HHC
  • these actually also exist on the HHS but is not implemented:

Parameter  | Range        | Default | Description
-----------|--------------|---------|--------------------------------------------------------
ta####     | 0000..1150   | 0250    | Target temperature [1/10 °C]
tb####     | 0001..3600   | 1800    | Timeout until starting of temperature supervision [s]
tc####     | 0000..1150   | 0020    | Tolerance for temperature supervision [1/10 °C]
td####     | 0000..1150   | 0060    | Security tolerance for temperature supervision [1/10 °C]
te####     | 0000..1150   | 0150    | Offset for hardware security temperature [1/10 °C]

questions:

• do the HHS and/or HHC have active cooling?
• in terms of the firmware API, do you know if the HHS is a strict superset of HHC?

[BioCam]

HHS has no active cooling

HHC definitely has active cooling

In terms of firmware I don't know, one has shaking, the other doesn't while one has cooling and the other doesn't

i propose adding back the accidentally removed HHC changes because there is no better current API. In the future, we should merge the HHS and HHC implementations as best we can and probably follow a similar model as we did with the HHS.
