SD card test
|
||||
|
||||
This example shows how use the utility libraries on which the'
|
||||
SD library is based in order to get info about your SD card.
|
||||
Very useful for testing a card when you're not sure whether its working or not.
|
||||
|
||||
|
||||
The circuit:
|
||||
* SD card attached to SPI bus as follows:
|
||||
** MOSI - pin 11 on Arduino Uno/Duemilanove/Diecimila
|
||||
** MISO - pin 12 on Arduino Uno/Duemilanove/Diecimila
|
||||
** CLK - pin 13 on Arduino Uno/Duemilanove/Diecimila
|
||||
** CS - depends on your SD card shield or module.

Pin 4 used here for consistency with other Arduino examples
