Function Documentation

__attribute__()

struct __attribute__

(

(packed)

)

pointer to the actual value

is the value allowed to be altered by the host?

length of the value

factor that should be applied to the returned values by the host. can be set to 0.0f to indicate that the value is a control value (not floating point)

turag_feldbus_stellantriebe_init()

void turag_feldbus_stellantriebe_init	(	feldbus_stellantriebe_command_t *	command_set,
		const char **	command_names,
		uint8_t	command_set_length,
		TuragFeldbusPacketProcessor	package_processor
	)

Sets up this module.

This function calls turag_feldbus_slave_init(), so you should not do this again.

Parameters

command_set	pointer to array containing the command set definition of the device
command_names	pointer to array of strings describing the command set
command_set_length	length of the command set
package_processor	This function is called upon the reception of packages that are not handled by the Stellantriebe protocol. Pass 0 if you don't need it.

turag_feldbus_stellantriebe_value_changed()

void turag_feldbus_stellantriebe_value_changed

(

uint8_t

key

)

This function is called after a value was changed.

You can use this function to start certain actions that have to follow the change of a value or you can check whether the new value is a valid one and if not, change it back using the variable feldbus_stellantriebe_old_value that always holds the original value of the entry that was changed last.

Parameters

key	of the changed value
