Create CSS class for this instead of the massive inlined style.
succd: Switch to libgpio to ensure GPIO states are reset when succd crashes
Right, but what does it reset to? And what's your reference for this, other than the docs which state 'may' (which doesn't inspire confidence)?
Investigate pirani gauge noise margins
The window is now 1 second (as we tick at 100Hz, but still capture 100 samples). It's actually a bit too noisy now IMO.
Should we implement some proper DSP to filter out high frequencies?
Add thermal sensor inputs to monitor diffusion pump temperature
Do you know of any off the shelf thermocouple sensor that we could interface to, eg. via a fieldbus or at some other high level? That might be the easiest and most reliable option.
Alternatively…
