| 11 | help |
| 12 | The "Serial Peripheral Interface" is a low level synchronous |
| 13 | protocol. Chips that support SPI can have data transfer rates |
| 14 | up to several tens of Mbit/sec. Chips are addressed with a |
| 15 | controller and a chipselect. Most SPI slaves don't support |
| 16 | dynamic device discovery; some are even write-only or read-only. |
| 17 | |
| 18 | SPI is widely used by microcontrollers to talk with sensors, |
| 19 | eeprom and flash memory, codecs and various other controller |
| 20 | chips, analog to digital (and d-to-a) converters, and more. |
| 21 | MMC and SD cards can be accessed using SPI protocol; and for |
| 22 | DataFlash cards used in MMC sockets, SPI must always be used. |
| 23 | |
| 24 | SPI is one of a family of similar protocols using a four wire |
| 25 | interface (select, clock, data in, data out) including Microwire |
| 26 | (half duplex), SSP, SSI, and PSP. This driver framework should |
| 27 | work with most such devices and controllers. |
