LED

Illuminate built-in LED on Raspberry Pi board

• 

Libraries:
Raspberry Pi Blockset / Basic

Description

Use the LED block to illuminate a user-controllable LED on the Raspberry Pi^® board. During simulations without the hardware, this block does nothing. See Block Produces Zeros or Does Nothing in Simulation (Simulink).

Do not specify the same LED in multiple blocks within a model.

Note

To generate code C/C++ code for this block, you must have an Embedded Coder^® license.

Ports

Input

Port_1 — Input signal

scalar

If the input to the block is a nonzero value, the LED specified in the LED parameter turns on. If the input to the block is zero, the LED specified in the LED parameter turns off.

For example, if the LED parameter is set to led0(Green) and the input to the block is 5, the green LED on the hardware starts glowing.

Data Types: uint8

Parameters

Board — Raspberry Pi hardware board

Pi 2 Model B (default) | Model B Rev1 | Model B Rev2 | Model B+ | Pi 3 Model B | Pi 3 Model B+ | Pi Zero W | Pi 4 Model B | Pi Zero 2 W | Compute Module 4 | Pi 5 Model
