SPI Register Read

Read data from SPI peripheral device register

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

• 

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

Description

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

Port_1 — Output port to read data

[Nx1] array

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

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

0 (default) | 1 | 2 | 3

Select the mode of SPI communication.

Register address — Register address to read the data

0 (default) | uint8 array

Enter the SPI peripheral register address to read the data.

Output data type — Data type for output

int8 (default) | uint8 | int16 | uint16 | int32 | uint32 | int64 | uint64 | single | double

Select the data type for SPI communication.

Output data length — Data length for SPI communication

1 (default) | scalar

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

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.

Sample time — Frequency to read data from the SPI peripheral device

0.1 (default)

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.
