R2026b

Write data to registers of an SPI peripheral device

• 

SPI Register Write block

To add a block to a model, double-click the canvas and start typing the block name. Then, select the block from the list.

Libraries:
Simulink Coder Support Package for BeagleBone Blue Hardware / Communication

Description

Add-On Required: This feature requires the Simulink Coder Support Package for BeagleBone Blue Hardware add-on.

The SPI Register Write block writes the block input data to specified register address. To open the pin map of the BeagleBone^® Blue 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 peripheral register.

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

Parameters

SPI Select — Pin connected to the SPI peripheral device

S1.1 (default) | S1.2

Select the pin number on the BeagleBone Blue board to which the SPI peripheral 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 peripheral register address to write the data.

Programmatic Use: Add Block

To add the block programmatically, use the add_block function with one of these library block paths as the source.

"bbblueCommlib/SPI Register Write"

Example: add_block("bbblueCommlib/SPI Register Write","myModel/myBlock",MakeNameUnique="on")
