Yes! Thank you. I used pip install pms5003==0.0.5 and pip install st7735==0.0.5 and all of the example scripts I’ve tried work! (and the display displays things!).
I feel a bit bad for not trying out the branch and seeing if it fixes things, but it bundles together a whole load of changes by the looks of it, so I’m a bit daunted a the prospect of giving it a go.
