What is then better? I2C? Yes, but then you need at least 2 wires (Clock and Data).
Is there another "low PIN cost" communication system?
You know what is not reliable are old prototype boards, that is why I prefer to use serial lcd to prove out code, as it uses 20 less connections. later it is simple to change over to lcdout routines, and if you use the lcd routine in My thread (mostly Darrel's code) then you can use standard lcdout type formatting so there is less to change.
