  • SPI Register Read block

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 Read block initiates an SPI read operation from an SPI peripheral register. You can specify the data type and data length to get data from the peripheral registers. To open the pin map of the BeagleBone® board, click the View pin map button.

Ports

Output

This port is the output port to read data from an SPI peripheral register.

Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64

Parameters

expand all

Select the mode of SPI communication.

Enter the SPI peripheral register address to read the data.

Select the data type for SPI communication.

Enter the output data length of the selected data type to read from the SPI peripheral register.

Select the pin number on the BeagleBone Blue board to which the SPI peripheral device is connected.

Specify how often the block reads data from the SPI peripheral device. When you specify this parameter as-1, Simulink® determines the best sample time for the block based on the block context within the model.

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 Read"

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

Version History

Introduced in R2018b
