Description

The Digital Read block outputs the logical state of a specified digital pin on the board.

During the external mode simulation, the block outputs the simulation results returned from the executable running on the target hardware.

During simulation in all other modes, the block outputs zeroes.

Ports

Output

expand all

The port outputs the logical state of the digital pin on the board that you specify in the Pin parameter.

Parameters

expand all

Specify the digital pin.

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

Make sure to assign different pin name to the different blocks of your model.

Specify in seconds how often this block reads the pin value.

When you specify this parameter as-1, Simulink® determines the best sample time for the block based on the block context within the 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.

"stm32nucleodiscoboardslib/Common/Digital Read"
"stm32f7lib/Digital Read"
"stm32f769ilib/Digital Read"
"stm32l475vglib/Digital Read"

Example: add_block("stm32nucleodiscoboardslib/Common/Digital Read","myModel/myBlock",MakeNameUnique="on")
