Presumably if you write a simple test program as described in https://luma-lcd.readthedocs.io/en/latest/python-usage.html#seven-segment-drivers, the driver works?

Yep!

but I’m not in a position to test this at the moment, could you try it?

Same here, but will do.

We can add it if you like?

Sound good (for newbies).

ps. using suggested code (and not the examples) worked fine for me (only tested numerals though).
