Which wires do you have connected? Just:
3.3v -> B3
B6 -> B7
B7 -> B6Yes - that's all.
Do you have ground connected between the two Picos as well?
Ah - I don't, no. I'll give it a try - thanks!
Edit: That seems to have fixed it - many thanks! Not knowing much about electronics that was seriously confusing the hell out of me - clearly I need to read up a lot more to get my head around more of these basic concepts. Thanks again!

If you don't, it's possible that could be causing your problems I guess?
