ec_sync_init()

void ec_sync_init	(	ec_sync_t *	sync,
		ec_slave_t *	slave
	)

Constructor.

Parameters

sync	EtherCAT sync manager.
slave	EtherCAT slave.

Definition at line 38 of file sync.c.

ec_sync_init_copy()

void ec_sync_init_copy	(	ec_sync_t *	sync,
		const ec_sync_t *	other
	)

Copy constructor.

Parameters

sync	EtherCAT sync manager.
other	Sync manager to copy from.

Definition at line 55 of file sync.c.

ec_sync_clear()

void ec_sync_clear

(

ec_sync_t *

sync

)

Destructor.

Parameters

sync	EtherCAT sync manager.

Definition at line 73 of file sync.c.

ec_sync_page()

void ec_sync_page	(	const ec_sync_t *	sync,
		uint8_t	sync_index,
		uint16_t	data_size,
		const ec_sync_config_t *	sync_config,
		uint8_t	pdo_xfer,
		uint8_t *	data
	)

ec_sync_add_pdo()

int ec_sync_add_pdo	(	ec_sync_t *	sync,
		const ec_pdo_t *	pdo
	)

Adds a PDO to the list of known mapped PDOs.

Returns

0 on success, else < 0

Parameters

sync	EtherCAT sync manager.
pdo	PDO to map.

Definition at line 145 of file sync.c.

ec_sync_default_direction()

ec_direction_t ec_sync_default_direction

(

const ec_sync_t *

sync

)

Determines the default direction from the control register.

Returns

Direction.

Parameters

sync	EtherCAT sync manager.
