What is an SPI driver?
The Serial Peripheral Interface (SPI) driver is a generic, full-duplex driver that transmits and receives data on a SPI bus. SPI is sometimes called SSI (Synchronous Serial Interface). Some SPI controllers feature a hardware chip select to assert SPI slave peripherals.
What is SPI controller?
The Serial Peripheral Interface (SPI) is a synchronous serial communication interface specification used for short-distance communication, primarily in embedded systems. The interface was developed by Motorola in the mid-1980s and has become a de facto standard.
What is the driver API for the SPI bus?
Driver API for SPI Bus Peripheral (Driver_SPI.h) The Serial Peripheral Interface Bus (SPI) implements a synchronous serial bus for data exchange. In microcontroller (MCU) applications, the interface is often used to connect peripheral components at board (PCB) level.
How is the SPI bus used for long distance communication?
Extending the SPI bus for long-distance communication The serial peripheral interface (SPI) bus is an unbalanced or single-ended serial interface designed for short-distance communication between integrated circuits. Typically, a master device exchanges data with one or multiple slave devices. The data exchange is full-duplex and requires syn-
What do you need to know about SPI device drivers?
SPI device drivers should initialize the name and owner field of this structure. This represents the kind of device driver that uses SPI messages to interact with the hardware at the other end of a SPI link.
Which is an example of a SPI communication protocol?
Introduction to SPI Communication. SPI is a common communication protocol used by many different devices. For example, SD card modules, RFID card reader modules, and 2.4 GHz wireless transmitter/receivers all use SPI to communicate with microcontrollers. One unique benefit of SPI is the fact that data can be transferred without interruption.
