Topic: SD Library - which pins ? (Read 792 times) previous topic - next topic

   Can anyone help me out and clarify which pins I should use for the SD library on the Due ?

   EDIT : Ok found the MOSI etc on the pin out, looks like I will have to solder up a quick adaptor before I can try the library.




You must use the "ICSP" pins.  Unfortunately this is the only access to SPI.


SPI: SPI header (ICSP header on other Arduino boards)
These pins support SPI communication using the SPI library. The SPI pins are broken out on the central 6-pin header, which is physically compatible with the Uno, Leonardo and Mega2560. The SPI header can be used only to communicate with other SPI devices, not for programming the SAM3X with the In-Circuit-Serial-Programming technique.

Bit of a mission, but got there finally.

I soldered jumpers directly to the SD Card and and have them connected to the Arduino through female headers soldered back to back. Not pretty but working.

Found the SD Card pinouts here -
