Description

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

Note

You can run a Simulink® model containing Digital Port Write block in Connected IO mode on STM32 Processor Based Boards. For more information, see Communicate with Hardware Using Connected IO.

Ports

Input

expand all

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

expand all

The 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

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

Programmatic Use

Block Parameter: PortName

Specify the GPIO digital pin to set the logical status.
