void pwmout_free ( pwmout_t * obj )

Deinitialize the pwmout object.

Parameters

obj	The pwmout object

void pwmout_init	(	pwmout_t *	obj,
		PinName	pin
	)

Initialize the pwm out peripheral and configure the pin.

Parameters

obj	The pwmout object to initialize
pin	The pwmout pin to initialize

void pwmout_period	(	pwmout_t *	obj,
		float	seconds
	)

Set the PWM period specified in seconds, keeping the duty cycle the same.

Periods smaller than microseconds (the lowest resolution) are set to zero.

Parameters

obj	The pwmout object
seconds	The floating-point seconds period

void pwmout_period_ms	(	pwmout_t *	obj,
		int	ms
	)

Set the PWM period specified in miliseconds, keeping the duty cycle the same.

Parameters

obj	The pwmout object
ms	The milisecond period

void pwmout_period_us	(	pwmout_t *	obj,
		int	us
	)

Set the PWM period specified in microseconds, keeping the duty cycle the same.

Parameters

obj	The pwmout object
us	The microsecond period

const PinMap* pwmout_pinmap ( void )

Get the pins that support PWM.

Return a PinMap array of pins that support PWM. The array is terminated with {NC, NC, 0}.

Returns: PinMap array

void pwmout_pulsewidth	(	pwmout_t *	obj,
		float	seconds
	)

Set the PWM pulsewidth specified in seconds, keeping the period the same.

Parameters

obj	The pwmout object
seconds	The floating-point pulsewidth in seconds

void pwmout_pulsewidth_ms	(	pwmout_t *	obj,
		int	ms
	)

Set the PWM pulsewidth specified in miliseconds, keeping the period the same.

Parameters

obj	The pwmout object
ms	The floating-point pulsewidth in miliseconds

void pwmout_pulsewidth_us	(	pwmout_t *	obj,
		int	us
	)

Set the PWM pulsewidth specified in microseconds, keeping the period the same.

Parameters

obj	The pwmout object
us	The floating-point pulsewidth in microseconds

float pwmout_read ( pwmout_t * obj )

Read the current float-point output duty-cycle.

Parameters

obj	The pwmout object

Returns: A floating-point output duty-cycle

void pwmout_write	(	pwmout_t *	obj,
		float	percent
	)

Set the output duty-cycle in range <0.0f, 1.0f>

Value 0.0f represents 0 percentage, 1.0f represents 100 percent.

Parameters

obj	The pwmout object
percent	The floating-point percentage number
