PWM outputs

v2 Usermod to add generic PWM outputs to WLED. Usermode could be used to control servo motors, LED brightness or any other device controlled by PWM signal.

Installation

Add the compile-time option -D USERMOD_PWM_OUTPUTS to your platformio.ini (or platformio_override.ini). By default upt to 3 PWM outputs could be configured, to increase that limit add build argument -D USERMOD_PWM_OUTPUT_PINS=10 (replace 10 by desired amount).

Currently only ESP32 is supported.

Configuration

By default PWM outputs are disabled, navigate to Usermods settings and configure desired PWM pins and frequencies.

Usage

If PWM output is configured, it starts to publish its duty cycle value (0-1) both to state JSON and to info JSON (visible in UI info panel). To set PWM duty cycle, use JSON api (over HTTP or over Serial)

{
    "pwm": {
        "0": {"duty": 0.1},
        "1": {"duty": 0.2},
        ...
    }
}
