Description

Read the logical value of a configured GPIO pin.

This block configures the general-purpose I/O (GPIO) MUX registers that control the operation of GPIO shared pins for digital input. Each I/O port has one MUX register that selects peripheral operation or digital I/O operation (the default). When a pin is configured for digital input, you cannot use the same pin for digital output or peripheral operation. You can configure the pull-up and the open-drain options for the individual digital input pins. To configure, go to Configuration Parameters > Hardware Implementation > Target Hardware Resources and select the appropriate GPIO group.

Ports

Output

Pin # — GPIO pin status

scalar | vector

The port outputs the status of the digital pin you select in the Pin number parameter.

Data Types: Boolean

Parameters

GPIO port — Port to read GPIO pin status

GPIOA (default) | GPIOBGPIOC…

Select one of GPIO ports to get the GPIO pin status.

Pin number — GPIO pin whose status you want to read

Pin 0 (default) | Pin 1 | Pin 2 | ...

Select the pin number of the GPIO pin whose status you want to read.

Sample time — Frequency at which block reads input pin values

-1 (default) | 0.1

Specify how often the block receives message, in seconds. 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.
