SPI Master Transfer

Write data to and read data from SPI slave device

• Library:

• Simulink Support Package for Raspberry Pi Hardware / Communication

• 

Description

Write data to and read data from an SPI slave device. To open the pin map of the Raspberry Pi board, click the View pin map button.

For more information on SPI communication refer to Support SPI Communication and The Raspberry Pi SPI Interface

Ports

Input

Port_1 — Input port to write data to SPI slave

[Nx1] or [1xN] array

The input port through which the block accepts a single dimensional array of values to write to the slave device.

Data Types: single | double | int8 | int16 | int32 | uint8 | uint16 | uint32

Output

Port_1 — Output port to read data from an SPI slave device

[Nx1] array

Output port from which the block receives data from SPI slave device.

Data Types: single | double | int8 | int16 | int32 | uint8 | uint16 | uint32

Parameters

Board — Specific board used for SPI communication

Pi 2 Model B (default) | Model B Rev1 | Model B Rev2 | Model B+ | Pi 3 Model B

Select the specific board that you are using. Changing the board updates the pin choices that you get.

Slave select pin — Slave select pin to which the SPI slave device is connected

SPI0_CE0 (default) | SPI0_CE1

Select the pin number on the Raspberry Pi™ board to which the SPI slave device is connected.

Mode (Clock polarity and phase) — Mode of SPI communication

0 (default) | 1 | 2 | 3

Select the mode for SPI communication.
