Read the state of five-position Joystick

• 

Joystick 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:
Raspberry Pi Blockset / Sense HAT

Description

Read the state of five-position Joystick. The block outputs a value between 0-5 based on the Joystick button pressed. The Joystick button positions are shown.

The positions on the Joystick that correspond to the five values of the block output are:

• 0- when you have not pressed a button

• 1- when you press the center button

• 2- when you press the left button

• 3- when you press the top button

• 4- when you press the right button

• 5- when you press the bottom button.

Note

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

Ports

Output

Port_1 — Output port to return value of the Joystick button

scalar

This is the output port that returns the value of the button pressed on Joystick.

Data Types: uint8

Parameters

View Position information — View the position of the Joystick button position

Click this button to know the position of the button pressed. The picture shows the positions of the Joystick button and the position of the other sensors on the SenseHAT board.

Sample time — Frequency at which data is read from pressure sensor

0.1 (default) | scalar

Specify how often this block reads the data from the pressure sensor.

Programmatic Use: Add Block

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

"sensehatlib/Joystick"

Example: add_block("sensehatlib/Joystick","myModel/myBlock",MakeNameUnique="on")
