Description

Write the logical status of a GPIO port pins for STM32 processors.

Examples

Getting Started with STMicroelectronics STM32 Processor Based Boards

Use the Embedded Coder® Support Package for STMicroelectronics® STM32 Processors to run a Simulink® model on an STMicroelectronics STM32 Processor Based hardware board.

Open Example

Ports

Input

Pin(s) — Set GPIO pin status

scalar | vector

The input port to set the GPIO pin status in incremental order.

• 0 - the respective pin is set to low value.

• Non zero - the pin is active low or active high.

Dependencies

To read multiple port values, select Access port pins as array parameter.

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

Output

msg Pin n — SoC Blockset™ simulation message

scalar | vector

he simulation-only message output port, when connected to an Digital IO Interface (SoC Blockset) block, acts as pass-through with the output emitted on the output of the Digital IO Interface block during simulation. When the Access port pins as array parameter is not selected, a simulation port is generated for each pin in the Pin number parameter, otherwise the pin array must be treated as a scalar.

Dependencies

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

Data Types: SoCData

Parameters

Port name — Port to write GPIO pin status

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

Select one of GPIOA to GPIOK ports to set a GPIO pin status of a specified GPIO port.

Pin number — GPIO port to set GPIO pin status

0 (default) | any range between 1 to 15

Specify the GPIO digital pin to set the logical status.

Access port pins as array — Input multiple pin values

on (default) | off

Select this parameter to read multiple port pin values.

Enable simulation port — Enable simulation ports to block

off (default) | on

Select this parameter to add an SoC Blockset compatible simulation output port.
