The SPI Master Synchronous Driver
|
|
=================================
|
|
|
|
The serial peripheral interface (SPI) is a synchronous serial communication
|
|
interface.
|
|
|
|
SPI devices communicate in full duplex mode using a master-slave
|
|
architecture with a single master. The master device originates the frame for
|
|
reading and writing. Multiple slave devices are supported through selection
|
|
with individual slave select (SS) lines.
|
|
|
|
Features
|
|
--------
|
|
|
|
* Initialization/de-initialization
|
|
* Enabling/disabling
|
|
* Control of the following settings:
|
|
|
|
* Baudrate
|
|
* SPI mode
|
|
* Character size
|
|
* Data order
|
|
* Data transfer: transmission, reception and full-duplex
|
|
|
|
Applications
|
|
------------
|
|
|
|
Send/receive/exchange data with a SPI slave device. E.g., serial flash, SD card,
|
|
LCD controller, etc.

Limitations
|
|
-----------
|
|
|
|
The slave select (SS) is not automatically inserted during read/write/transfer,
|
|
user must use I/O to control the devices' SS.
