osal_uint32_t | handler_flags |
Flags signalling handler recv of send action. | |
osal_mutex_t | sync_mutex |
Sync mutex for handler flags. | |
osal_binary_semaphore_t | sync_sem |
Mailbox sync semaphore. | |
int | handler_running |
Mailbox handler thread running flag. | |
ec_t * | pec |
Pointer to ethercat master structure. | |
int | slave |
Number of EtherCAT slave. | |
osal_task_t | handler_tid |
Mailbox handler thread handle. | |
osal_mutex_t | lock |
mailbox lock | |
int | seq_counter |
mailbox sequence counter | |
pool_t | message_pool_send_queued |
Pool with mailbox buffers ready to be sent. | |
osal_uint32_t | sm_state_bitno |
osal_uint8_t * | sm_state |
Sync manager state of read mailbox. | |
osal_uint8_t | mbx_state |
State if not mapped. | |
osal_mutex_t ec_mbx::lock |
mailbox lock
Only one simoultaneous access to the EtherCAT slave mailbox is possible at the moment.
ec_t* ec_mbx::pec |
Pointer to ethercat master structure.
Used by handler thread wrapper to call mailbox handler function.
int ec_mbx::slave |
Number of EtherCAT slave.
Used by handler thread wrapper to call mailbox handler function.
osal_uint8_t* ec_mbx::sm_state |
Sync manager state of read mailbox.
The field is used to receive the mailbox sync manager state. This is useful to determine if the mailbox is full or empty without the need to poll the state manually.
