9 | The "Serial Peripheral Interface" is a low level synchronous | |
10 | protocol. Chips that support SPI can have data transfer rates | |
11 | up to several tens of Mbit/sec. Chips are addressed with a | |
12 | controller and a chipselect. Most SPI slaves don't support | |
13 | dynamic device discovery; some are even write-only or read-only. | |
14 | ||
3cb2fccc | 15 | SPI is widely used by microcontrollers to talk with sensors, |
8ae12a0d DB |
16 | eeprom and flash memory, codecs and various other controller |
17 | chips, analog to digital (and d-to-a) converters, and more. | |
18 | MMC and SD cards can be accessed using SPI protocol; and for | |
19 | DataFlash cards used in MMC sockets, SPI must always be used. | |
20 | ||
21 | SPI is one of a family of similar protocols using a four wire | |
22 | interface (select, clock, data in, data out) including Microwire | |
23 | (half duplex), SSP, SSI, and PSP. This driver framework should | |
24 | work with most such devices and controllers. | |
