Example Code for Intel Joule-PWM Control

Last revision 2026/01/24

The article features sample code for controlling Intel Joule's PWM using JS+MRAA, focusing on setting an 80% duty cycle to demonstrate continuous PWM wave output.

Sample Code

JS+MRAA init PWM32, enable it and set duty cycle to 0.8.

var mraa = require('mraa');
var pin = new mraa.Pwm(32);
pin.enable(true);
pin.write(0.8)

Result

PWM32 continuously outputs PWM wave with 80% duty cycle.
