Function Documentation

ec_fsm_master_exec()

int ec_fsm_master_exec

(

ec_fsm_master_t *

fsm

If the state machine's datagram is not sent or received yet, the execution of the state machine is delayed to the next cycle.

Returns

true, if the state machine was executed

Parameters

fsm	Master state machine.

ec_fsm_master_idle()

int ec_fsm_master_idle

(

const ec_fsm_master_t *

fsm

)

Returns

true, if the state machine is in an idle phase

Parameters

fsm	Master state machine.
