Function Documentation

pwm_duty()

void pwm_duty

(

uint8_t

duty

)

Set the duty cycle.

Sets the duty cycle of the pulse width modulated signal.

Parameters

duty	The duty cycle per cent.

pwm_init()

void pwm_init

(

void

)

Initialize PWM module.

Initializes the PWM module but does not yet start the modulation.

pwm_start()

void pwm_start

(

void

)

Start the modulation.

Start the modulation on the oscillator pin.

pwm_stop()

void pwm_stop

(

void

)

Stop the modulation.

Stops the modulations, clears the oscillator pin and resets the PWM timer.
