bool "SPI support"

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.

This simple GPIO bitbanging SPI master uses the arch-neutral GPIO

interface to manage MOSI, MISO, SCK, and chipselect signals. SPI

slaves connected to a bus using this driver are configured as usual,

Note that this driver often won't achieve even 1 Mbit/sec speeds,

GPIO operations, you should be able to leverage that for better

speed with a custom version of this driver; see the source code.
