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