Hi,

Has anyone ever tried a communication between Propeller chip with Basic Stamp? I have Propeller Activity Board and BS2PX chip and I want to make the propeller as the "master" communication.
Is I/O pin connection between both of them is the answer? Is it even possible? Any circuit diagram will be helpful! Thanks

    I do it all the time with half-duplex, "open-true" serial coms. Put a 10k pull-up to 5V on the BS2px side and you're set. To be clear, you'll have one bi-directional serial IO pin, and, of course, you'll need to have common ground between the two boards. Since you may be using WAIT modifiers in SERIN, make sure you select a tame baud rate like 9600 (again, open-true). And, yes, FullDuplexSerial can be configured for half-duplex, open-true coms.
