void pwm_initPWMCH_enum pwmch uint32 freq uint32 duty;

The function pwm_init is used to initialize the PWM channel with the specified frequency and duty cycle.

Parameters:

• pwmch: The PWM channel to be initialized (PWMCH_enum type)
• freq: The desired frequency of the PWM signal in Hz (uint32 type)
• duty: The desired duty cycle of the PWM signal in percentage (uint32 type)

Return Type: void

Example usage: pwm_init(PWMCH0, 1000, 50); This initializes PWM channel 0 with a frequency of 1000 Hz and a duty cycle of 50%.
