Is there a best practices for interfacing 5v TTL logic with the 3.3v logic on the GPIO pins? I was thinking a bi-directional shifter would be good, but there are so many different ways to do this. Is there a best current practice for this? -- Bryan Fields 727-409-1194 - Voice http://bryanfields.net
