writePWMDutyCycle

Generate PWM signal with specified duty cycle on digital pin

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

Syntax

writePWMDutyCycle(a, pin, dutyCycle)

Description

writePWMDutyCycle(a, pin, dutyCycle) sets the PWM duty cycle on a digital pin specified for the Arduino^® hardware a.

Examples

Specify the Duty Cycle of Digital Pin

Specify a 0.33 duty cycle for an LED attached to digital pin 5 on Arduino hardware.

a = arduino();
writePWMDutyCycle(a,'D5',0.33);

Input Arguments

a — Arduino hardware connection

object

Arduino hardware connection created using arduino, specified as an object.

pin — Digital pin number

character vector

Digital pin number on the physical hardware, specified as a character vector.

dutyCycle — Value of the digital pin duty cycle

numeric

Value of digital pin’s PWM duty cycle specified as number between 0 and 1.

More About

Code Generation Using MATLAB Function Block

• Use writePWMDutyCycle in a MATLAB^® Function block with the Simulink^® Support Package for Arduino Hardware to generate code that can be deployed on Arduino Hardware.

• Configure the Arduino peripherals to the appropriate mode using configurePin before using writePWMDutyCycle in the MATLAB Function block.
