Function Documentation

up_pwm_trigger_arm()

__EXPORT void up_pwm_trigger_arm

(

bool

armed

)

Arm or disarm trigger outputs.

Bug:

This function should, but does not, guarantee that any pulse currently in progress is cleanly completed.

Parameters

armed

If true, outputs are armed; if false they are disarmed.

up_pwm_trigger_deinit()

__EXPORT void up_pwm_trigger_deinit

(

void

)

De-initialise the PWM trigger outputs.

up_pwm_trigger_init()

__BEGIN_DECLS __EXPORT int up_pwm_trigger_init

(

uint32_t

channel_mask

)

Intialise the PWM servo outputs using the specified configuration.

Parameters

channel_mask

Bitmask of channels (LSB = channel 0) to enable. This allows some of the channels to remain configured as GPIOs or as another function.

Returns

OK on success.

up_pwm_trigger_set()

__EXPORT int up_pwm_trigger_set	(	unsigned	channel,
		uint16_t	value
	)

Set the current output value for a channel.

Parameters

channel	The channel to set.
value	The output pulse width in microseconds.
