PWM Example

Overview

This sample exercises the PWM HAL with a focus on synchronous multi-channel output, dynamic frequency and duty-cycle changes, and readback verification.

Source file: src/rtsmart/examples/peripheral/pwm/test_pwm.c

Default Setup

• Maps PWM0 to PIN42

• Maps PWM1 to PIN43

Key APIs

• drv_pwm_init() / drv_pwm_deinit()

• drv_pwm_set_freq() / drv_pwm_get_freq()

• drv_pwm_set_duty() / drv_pwm_get_duty()

• drv_pwm_enable() / drv_pwm_disable()

• drv_fpioa_set_pin_func()

Build and Run

cd src/rtsmart/examples/peripheral/pwm
make
./test_pwm

The sample has no command-line parameters.
