Module pwm

Pulse wave modulation (PWM) driver for RP2040.

Hardware Interface Layer (HIL)

The driver implements both Pwm and PwmPin HILs. The following features are available when using the driver through HIL:

• Configurable top and compare values
• Independent configuration for each channel and for each output/input pin
• Duty cycle from 0% to 100% inclusive

Examples

The integration tests for Raspberry Pi Pico provide some examples using the driver. See boards/raspberry_pi_pico/src/test/pwm.rs
