I am attempting to connect a microSD breakout board to a LilyPad Arduino USB. The microSD board has previously been connected to an Arduino Duemilanove.
In the Duemilanove setup, the following connections were made successfully:
(SD) -> Duemilanove
- (CS) -> Pin 10 (SS)
- (DI) -> Pin 11 (MOSI)
- (DO) -> Pin 12 (MISO)
- (CLK) -> Pin 13 (SCK)
Plus 5 V and ground.
I have attempted to replicate this with the LilyPad USB, following the schematic.
(SD) -> LilyPad USB
- (CS) -> Pin D17 (SS)
- (DI) -> Pin D16 (MOSI)
- (DO) -> Pin D14 (MISO)
- (CLK) -> Pin D15 (SCK)
However, the problem is, I cannot locate this digital pins physically on the LilyPad USB. I believe they are the six pins in a rectangle formation next to analogue port A2, but I do not know which are which. Following the forum post LilyPad USB v1.1 and SPI, I have tried that combination, but I have not had any results.
What is the order of the six pins? Also, where is the SS pin (that doesn't seem to be included there)?
