SPI Register Write

Write data to registers of an SPI slave device

• Library:

• Simulink Support Package for Raspberry Pi Hardware / Communication

• 

Description

The SPI Register Write block writes the block input data to specified register address. To open the pin map of the Raspberry Pi board, click the View pin map button.

Ports

Input

Port_1 — Input port to accept data

[Nx1] or [1xN] array

The input port to accept data to write the data to the SPI slave register.

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

Parameters

Board — SPI module used for communication

Pi 2 Model B (default) | Model B Rev1 | Model B Rev2 | Model B+ | Pi 2 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 — Pin connected to the SPI slave device

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 SPI communication mode.

Register address — Register address to write the data

0 (default) | uint8 array

Enter the slave register address to write the data.
