Although MM and SD Cards are designed to operate with their own special bus wiring and protocols, both types of cards also provide a simple SPI-like interface mode which is exceptionally useful when attempting to use the cards in embedded systems.</dd></dl> |
||
| 14 | <dl compact><dt><b>Wiring</b></dt><dd>To work with this library, the card must be wired to the SPI port of the Atmel microcontroller as described below. Typical cards can operate at up to 25MHz maximum SPI clock rate (thus faster than most AVR's maximum SPI clock rate). <pre> |
