Description

Set the logical value of a digital pin of the STM32F4 -Discovery™ board.

Examples

Getting Started with Embedded Coder Support Package for STMicroelectronics Discovery Boards

Demonstrates how to use the Embedded Coder® Support Package for STMicroelectronics® STM32 Processors to run a Simulink® model on an STMicroelectronics STM32F4-Discovery, STM32F746G-Discovery, or STM32F769I-Discovery board.

Open Example

Push Button and LED

Use the GPIO blocks in the STMicroelectronics® STM32F4-Discovery library to control the push-button and the LED's on the STMicroelectronics® STM32F4-Discovery board.

Open Example

G.729 Voice Activity Detection for STM32 Processor Based Board

Model the ITU-T G.729 Voice Activity Detector (VAD) algorithm and run it on the ARM® Cortex®-M based STMicroelectronics® STM32 boards using Embedded Coder® Support Package for STMicroelectronics STM32 Processors.

Open Model

Asynchronous Scheduling for STM32F4-Discovery Board

Ports

Input

Port_1 — Set the GPIO pin status

scalar

The input port to set the GPIO pin status.

Data Types: single | double | int8 | int16 | int32 | uint8 | uint16 | uint32 | Boolean | fixed point | enumerated | bus

Parameters

GPIO port — GPIO port to set the GPIO pin status

GPIOA (default) | GPIOA | GPIOB | GPIOC | GPIOD | GPIOE | GPIOF | GPIOG | GPIOH | GPIOI

Select one of GPIOA to GPIOI ports to set a GPIO pin status.

Pin number — GPIO port to set the GPIO pin status

1 (default)

Select a GPIO pin to write the logical status.

Initially set GPIO pin — Option to set the GPIO pin status during model initialization

off (default) | on

Select this option to set the GPIO pin status during model initialization.

Toggle pin when input is true — Option to enable GPIO pin toggling when the input is true

off (default) | on

Select this option to enable GPIO pin toggling when the input is ‘true’.
