No, ICSP is for programming only. My schematics has an (non-standard) 8-pin ICSP, the basic one + serial rx/tx + PGM (for low voltage programming - I don't think I actually use it, but it is on the wisp...) > I'm thinking again about flow control.

I'd prefer a 6-pin connector (or 7, when you add +7v) over a smaller one and jumpers to select the signal. This because you can use all signals at the same time if you have a use for it. An alternative would be 2 connectors - one for i2c and one for serial (and that one with rx and tx). > Joep --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "jallib" group.
