decrementResourceCount

R2026b

Decrement count of number of instances of resource

Syntax

count = decrementResourceCount(arduinoObj, resource)

Description

Add-On Required: This feature requires the MATLAB Support Package for Arduino Hardware add-on.

count = decrementResourceCount(arduinoObj, resource) decrements current count of instances of the specified resource by one and returns the updated count. Call this function in your custom Arduino library Destructor.

Examples

Decrement Count of Servo

Decrement the resource count of a servo created with the parent arduino object.

arduinoObj = obj.Parent;			% In the constructor
incrementResourceCount (arduinoObj, 'servo')

1

decrementResourceCount (arduinoObj, 'servo');		% In destructor

0

Input Arguments

arduinoObj — Arduino^® object

object

Arduino object, specified as an object that is an internal variable called from within classes that derive from matlabshared.addon.LibraryBase.

resource — Name of resource to decrement

character vector

Name of resource to decrement, specified as a character vector. The resource must be added to the arduino object before using incrementResourceCount.
