As they are addressable, I want to stack the relayplus boards.
I can use all the relays/inputs/outputs on a single plus board and extra board not a problem.
I am just not sure of the syntax and I cant find any documentation referring to the addressing of multiple boards.
I gather the address is set in the initialisation code ie pfr = pifacerelayplus.PiFaceRelayPlus(pifacerelayplus.RELAY).
Any one have any ideas?
