Set logical state of digital output pin

• 

Digital Write block

To add a block to a model, double-click the canvas and start typing the block name. Then, select the block from the list.

Libraries:
STM32 Microcontroller Blockset / (Legacy) STM32 MBED Based Boards / Common
STM32 Microcontroller Blockset / (Legacy) STM32 MBED Based Boards / STM32F746G-Discovery
STM32 Microcontroller Blockset / (Legacy) STM32 MBED Based Boards / STM32F769I-Discovery
STM32 Microcontroller Blockset / (Legacy) STM32 MBED Based Boards / STM32L475VG-Discovery (B-L475E-IOT01A)

Description

The Digital Write block sets the logical state of the specified digital pin on the board.

During the external mode simulation, the block sets the value to the pin that you specify in the Pin parameter.

During simulation in all other modes, the block does nothing.

Ports

Input

Port_1 — Input signal

scalar

The block sets this value to the digital output pin that you specify in the Pin parameter.

Parameters

Pin — Pin number of the digital output

Specify the digital pin.

To open the pin mapping table, click View pin map.

Make sure not to assign the same pin name to multiple blocks within your model.

Programmatic Use: Add Block

To add the block programmatically, use the add_block function with one of these library block paths as the source.
