Digital Input 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:
Simulink Coder Support Package for VEX EDR V5 Robot Brain / Sensors

Description

Add-On Required: This feature requires the Simulink Coder Support Package for VEX EDR V5 Robot Brain add-on.

The Digital Input block reads the logical value from the selected 3-wire port on VEX^® EDR V5 Robot Brain. You can use up to eight 3-wire ports on the VEX EDR V5 Robot Brain to read logical values.

Ports

Output

Port_1 — Logical value read from the 3-wire port

0 | 1

Logical value read from the 3-wire port, returned as a boolean value.

Data Types: Boolean

Parameters

3-Wire Expander (smart port) — Select the smart port that is used by 3-Wire Expander

None (default) | 1 to 21

If you are using a 3-Wire Expander, specify the smart port on VEX EDR V5 Robot Brain to which the expander is connected.

Port — Select the 3-wire port to read the logical value

A (default) | A to H

Select the 3-wire port on the VEX EDR V5 Robot Brain from which you want to read the digital signal.

Do not assign the same port to more than one Digital Input block within the same model.

Sample time — Sample time for obtaining the value from the 3-wire port

0.2 (default) | seconds

Specify how often the block should read the values from the 3-wire port.

Programmatic Use: Add Block

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

"vexv5lib/Sensors/Digital Input"

Example: add_block("vexv5lib/Sensors/Digital Input","myModel/myBlock",MakeNameUnique="on")
