PWM (Pulse Width Modulation) is a technique for digitally encoding analog signal levels.
The RTOS includes a PWM driver, enabling applications to access the PWM device via the
PWM device management interface provided by RT-Thread, through which they can configure
parameters such as period and duty cycle. Additionally, the system includes a test
program capable of setting the PWM duty cycle of PWM, which is located at
rtthread/bsp/starfive/jh7110/applications/pwm_test.c.
