GPIO Write

Set GPIO pin status

Add-On Required: This feature requires the Simulink Support Package for Raspberry Pi Hardware add-on.

• 

Libraries:
Simulink Support Package for Raspberry Pi Hardware / Basic

Description

Use the GPIO Write block to set the logical value of a digital pin of your Raspberry Pi^® board.

Warning

You can damage your target hardware by:

• Exceeding the maximum voltage that can be applied to GPIO pins.

• Shorting a GPIO pin to ground.

• Shorting a GPIO pin with high voltage to another GPIO pin with low voltage.

• Connecting a GPIO pin to a voltage source greater than the maximum voltage.

• Exceeding the maximum current by driving multiple GPIO pins high simultaneously.

Ports

Input

Port_1 — Set GPIO pin status

scalar

The block accepts a logical value to set the status of a digital pin.

Data Types: Boolean

Parameters

Board — Raspberry Pi hardware board

Model B+ (default) | Model B Rev1 | Model B Rev2 | Pi 2 Model B | Pi 3 Model B | Pi 3 Model B+ | Pi Zero W | Pi 4 Model B | Compute Module 4 | Pi Zero 2 W

Select your Raspberry Pi hardware board. You can find this information on the target hardware, product packaging, or product documentation.

GPIO number — GPIO pin of Raspberry Pi hardware board

4 (default) | 17 | 27 | 22 | 10 | 9 | 11 | 14 | 15 | 18 | 23 | 24 | 25 | 8 | 7 | 5 | 6 | 12 | 13 | 19 | 16 | 26 | 20 | 21

Select a GPIO pin of the Raspberry Pi hardware board to set its logical status. Do not use the same GPIO pin in multiple blocks within the Simulink^® model. For more information on Raspberry Pi GPIO pins, click View pin map.
