PWM_Config

Definition

    typedef struct {
        float dutyCycle; 
        Timer_Config timer;
        Pin pin; //our output pin
        uint8 enable;
        PWM_Channel channel;
    }PWM_Config;

Description

The PWM_Config structure is used for configuring a PWM channel for use.

Parameters

• dutyCycle: this should be a value between 0 and 1 and specifies the duty cycle of the PWM waveform.
• timer: this should be a complete filled out and initialized timer structure that will be used for the PWM generation. Only the PWM frequency depends on this structure. The timer structure can only utilize timers 2 and 3 for PWM generation. No other timers may be used.
• pin: This should be the desired output pin. Please refer to the documentation on page 11 and 12 to determine which pins are available for use by your selected PWM channel specified in channel.
• enable: this parameter specifies whether the PWM should be enabled after configuration
• channel: this specifies which PWM channel will be used. Each channel can only be used to generate a single PWM waveform.
