Very new to Fritzing, it is awesome! Thank you.
I have a test shield for the Uno that has a built-in SD card. My project has exceeded the capacity of an Uno and was looking to use a Mega 2560. Plugged in my card only to find the SPI pins on the mega have moved to the ICSP header. Most of my shields use the SPI pins on the Uno, 11, 12, 13 I believe they are…
It seems one can make an adapter shield with jumpers of some sort that can ‘map’ the functionality of the SPI pins between 11, 12, 13 to the ICSP header, maybe another setting to make the pins pass-thru to other shield, etc.
Before going down this path, surely someone has done this already or there is some obvious problem that I am missing.
Let’s say I have to make one or decide to make one of my own for whatever reason… The ICSP header I would want to use would be a long pinned female type connector pass-thru hole … ? I did not find this part in the large list of parts. Am I missing it?
Lastly, if I add my own SD card, is there a chip of some sort needed? Or do the pins go directly to the ICSP pins? My existing shield looks like it has a real small ship with no markings that I can see.
