getDisplayEnvironment

Get display environment value that NVIDIA hardware uses

Syntax

displayValue = getDisplayEnvironment(hwObj)

Description

Add-On Required: This feature requires the MATLAB Coder Support Package for NVIDIA Jetson and NVIDIA DRIVE Platforms add-on.

displayValue = getDisplayEnvironment(hwObj) shows the display environment value that generated applications use on the NVIDIA^® hardware. For example, if you deploy an application that uses the image function onto NVIDIA hardware, the application displays the image in the environment that getDisplayEnvironment returns.

Examples

Check Display Target of Jetson Board

Create a jetson object. Check the display environment that the object uses. In this example, the live connection uses display environment 0.0.

hwObj = jetson;
getDisplayEnvironment(hwObj);

ans =

    '0.0'

Input Arguments

hwObj — Connection to a specific NVIDIA hardware board

jetson object | drive object

Connection to a specific NVIDIA hardware board, specified as a jetson or drive object.

Output Arguments

displayValue — Display environment value

character vector

Display environment value, returned as a character vector in the format 'X.Y', where X is the display number and Y is the screen number.

If you have used the setDisplayEnvironment function before, the displayValue that the function returns is the most recent value that you set. If you have not set the display environment value before, the default value is '1.0'.

Example: '0.0'

Version History

Introduced in R2019a

R2026a: Default display value changed

If you have not set the display environment before, the default value that getDisplayEnvironment returns is '1.0'. In previous releases, the default value was '0.0'.
