Digital Port Read

Read GPIO pin(s) status

Since R2022b

• 

Libraries:
Embedded Coder Support Package for Infineon AURIX TC4x Microcontrollers / AURIX TC4x

Description

Read the logical status of a GPIO port pin for the Infineon AURIX TC4x Microcontrollers.

Ports

Input

msg — SoC Blockset simulation message

scalar

This port receives the SoC Blockset™ message from the interface blocks and the Digital Port Read block converts the msg into data to be emitted at the output port during simulation.

Dependencies

To view this port, select the Enable simulation port parameter and set the port type as SoC Data (Message based).

sig — Simulink based simulation signal

scalar | vector

The simulation-only signal input port acts as pass-through with the output of the Digital Port Read block during simulation.

Dependencies

To view this port, select the Enable simulation port parameter and set the port type as Signal.

Output

Pin(s) — GPIO pin status

scalar | vector

The port outputs the status of the digital pin you select in the Port number and Pin number parameter from Digital Port Read Peripheral Configuration.

The port outputs the status as a logical scalar if the pin number is 1 or as a logical vector if it is greater than 1.

Data Types: Boolean

Parameters

Number of pins — Number of pins you want to configure

1 (default) | 2 | 3 | ...

Select the number of pins (1 to 16) whose output you want to configure in the block.

Sample time — Frequency at which block reads input pin values

-1 (default) | scalar | vector

Specify in seconds how often the block should read the pin value.

When you specify this parameter as -1, Simulink^® determines the best sample time for the block based on the block context within the model.

Enable simulation port — Enable peripheral simulation ports in the block

off (default) | on

Select this parameter to enable peripheral simulation capability.

Note

If you do not have a SoC Blockset license, the Enable simulation port parameter is visible but you cannot enable it.

Port Type — Specify the type of peripheral simulation port

SoC Data (Message based) (default) | Signal

Select this parameter to configure either the SoC Blockset compatible or the Simulink signal based simulation ports to enable peripheral simulation capability.

Dependencies

To view this parameter, select the Enable simulation port parameter.
