Detailed Description

EtherCAT FMMU configuration structure.

Definition in file fmmu_config.h.

Function Documentation

ec_fmmu_config_init()

void ec_fmmu_config_init	(	ec_fmmu_config_t *	fmmu,
		ec_slave_config_t *	sc,
		ec_domain_t *	domain,
		uint8_t	sync_index,
		ec_direction_t	dir
	)

FMMU configuration constructor.

Inits an FMMU configuration, sets the logical start address and adds the process data size for the mapped PDOs of the given direction to the domain data size.

Parameters

fmmu	EtherCAT FMMU configuration.
sc	EtherCAT slave configuration.
domain	EtherCAT domain.
sync_index	Sync manager index to use.
dir	PDO direction.

ec_fmmu_config_page()

void ec_fmmu_config_page	(	const ec_fmmu_config_t *	fmmu,
		const ec_sync_t *	sync,
		uint8_t *	data
	)

Initializes an FMMU configuration page.

The referenced memory (data) must be at least EC_FMMU_PAGE_SIZE bytes.

Parameters

fmmu	EtherCAT FMMU configuration.
sync	Sync manager.
data	Configuration page memory.
