Version 1.4.0:

    10

    11

* Slave config allow flag and completion object.

    14

* READMEs for examples.

    15

* Remove get_cycles() calls and references to cpu_khz to increase

    16

  portability.

    17

* Remove ecdb.h and let lsec output PDO information 'cut-and-pastable' for

    18

  applications.

    19

* SDO write access in sysfs.

    20

* Distributed clocks.

    21

* Update documentation.

    22

* Do not configure in ecrt_master_activate(), but later in the state machine.

    23

* Remove master_state_t.

    24

* Scanning of Sdo dictionary / writing EEPROM in OPERATION state.

    25

* Adapt remaining examples.

    26

* Separate Pdo and Pdo entry classes.

    27

* Attach Pdo names.

    28

* Make all define underscores the same.

    29

* Remove bus validation; make bus scanning possible at any time.

    30

* Re-design slave configuration FSM, avoid unnecessary process data

    31

  interruptions.

    32

* Wait for bus scanning, even when link is not up at ecrt_request_master().

    33

* Implement ecrt_slave_config_state().

    34

    35

Future issues:

    36

    37

* Move slave handlers and state machines, etc. into a user space daemon.

    38

    - Step 1: Replace Sysfs interface with cdev and a user space program

    39

              to replace lsec.

    40

    - Step 2: Move kernel threads to user space daemon with a TCP interface

    41

              replacing the cdev.

    42

* Mailbox gateway.

    43

* Slave-to-slave communication.

    44

* Redundancy with 2 network adapters.

    45

* Interface/buffers for asynchronous domain IO.

    46

    47

Smaller issues:

    48

    50

* Unite fsm_pdo_mapping, fsm_pdo_config and fsm_coe_map.

    51

* Clear sync managers in INIT.

    52

* Simplify FSMs with <state>_enter() functions.

    53

* Read out CRC counters.

    54

* Optimize alignment of process data.

    55

* Evaluate EEPROM contents after writing.

    56

* Configure slave ports to automatically open on link detection.

    57

* Interrupt master state machines state scan for other jobs.

    58

* Master state machine, slave configuration: Do not check every slave on

    59

  a cycle.

    60

* Only execute one EoE handler per EoE cycle.

    61

    62

Less important issues:

    63

    64

* File access over EtherCAT (FoE).

    65

* Allow VLAN tagging.

    66

* Determine number of frames, the NIC can handle.
