Description

Set the logical value of a digital pin of the 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’.
