SPI Controller Transfer

Write data to and read data from SPI peripheral device

Add-On Required: This feature requires the Simulink Support Package for Raspberry Pi Hardware add-on.

• 

Libraries:
Simulink Support Package for Raspberry Pi Hardware / Communication

Description

Write data to and read data from an SPI peripheral 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 Raspberry Pi SPI Interface

Ports

Input

Port_1 — Input port to write data to SPI peripheral

[Nx1] or [1xN] array

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

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

Output

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

[Nx1] array

Output port from which the block receives data from SPI peripheral 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 | Pi 3 Model B+ | Pi Zero W | Pi 4 Model B | Pi Zero 2 W | Compute Module 4 | Pi 5 Model

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

Chip select pin — Chip select pin to which the SPI peripheral device is connected

SPI0_CE0 (default) | SPI0_CE1 | SPI1_CE0 | SPI1_CE1 | SPI1_CE2

Select the pin number on the Raspberry Pi^® board to which the SPI peripheral device is connected.

To enable the secondary SPI bus on your Raspberry Pi hardware, follow the steps as mentioned in Enable Secondary SPI Bus of Raspberry Pi Hardware.

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

0 (default) | 1 | 2 | 3

Select the mode for SPI communication.

For more information on mode, refer to SPI Transfer Modes
