I'd like to know if anyone has any experience with using the STK200 programming cable (it comes out to a 5x2 female connector) as the programming interface for a new design. I want to build the ISP capability into a board but I don't understand why certain things were done on the STK200 schematic. Can the MOSI, MISO, SCK lines go straight to the uC to be programmed if I don't use those lines for anything else? Or do they need to be pulled up or down?

Thanks.

Patrick,
I use this Kanda standard on ALL my PCBs. The STK200
software works well.

If you don't use the MISO MOSI and SCK lines for anything else you can connect them directly from
the AVR to the ISP connector.
If in your design do you have some output for LED's (or similar) or input keys you can connect
them to MISO MOSI and SCK to avoid to loose these I/O.
