Version 1.5.0:

    12

    13

* Distributed clocks:

    14

    - Check 32/64 bit operations.

    15

    - Use vendor correction factors when calculating transmission delays.

    16

    - Skip setting system time offset when application detached.

    17

    - How to set the SYNC1 shift time?

    18

    - Do not output graph, if topology calculation failed.

    19

    - Set the "Cyclic Generation Start Time" based on the slave's

    20

      "System Time" register instead of using the application time.

    21

    - Check if register 0x0980 is working, to avoid clearing it when

    22

      configuring.

    23

* Fix unloading problem of ec_e100 driver.

    24

* Use ec_datagram_zero() where possible.

    25

* Fix arguments of reg_read.

    26

* Sign/Abs type for reg_ commands?

    27

* Number layout for reg_read.

    28

* Show Record / Array / List type of SDOs.

    29

* Limit bandwidth of state machine datagram.

    30

* Read alias from register 0x0012 instead of SII.

    31

* Finish library implementation.

    32

* Re-work EoE code.

    33

* Replace locking callbacks.

    34

* Implement EoE callbacks for library.

    35

* Rescan command.

    36

* Override sync manager size?

    37

* Remove ecrt_domain_state()?

    38

* Check force_config flag before error.

    39

* Remove allow_scanning flag.

    40

* Test File access over EtherCAT (FoE) reading.

    41

* Implement ecrt_master_slave() in kernel space.

    42

* Check for ioctl() interface version.

    43

* Improve application-triggered SDO transfers by moving the statemachine into

    44

  the SDO handlers.

    45

* Apply watchdog patches from J. Mohre.

    47

    48

Future issues:

    49

    50

* Segmented SDO downloads.

    51

* External memory for SDO transfers.

    52

* Bus information via userspace library (slaves, sync managers, PDOs, entries).

    53

* C++ implementation of the library.

    54

* Bus simulator interface.

    55

* Move master threads, slave handlers and state machines into a user

    56

  space daemon.

    57

* Allow master requesting when in ORPHANED phase

    58

* Mailbox protocol handlers.

    59

* Mailbox state machine using toggle bits.

    60

* Mailbox gateway.

    61

* Separate CoE debugging.

    62

* Evaluate EEPROM contents after writing.

    63

* Optimize alignment of process data.

    64

* Redundancy with 2 network adapters.

    65

* Interface/buffers for asynchronous domain IO.

    66

* Make scanning and configuration run parallel (each).

    67

* ethercat tool:

    68

    - Data type abbreviations.

    69

    - Add a -n (numeric) switch.

    70

	- Check for unwanted options.

    71

* Simplify master fsm by introducing a common request state to handle external

    72

  requests (replace write_sii, sdo_request, etc).

    73

    74

Smaller issues:

    75

    76

* Stop master thread at ecrt_master_request() to get rid of allow_* flags?

    77

* Clear sync managers in INIT.

    78

* Read out CRC counters.

    79

* Configure slave ports to automatically open on link detection.

    80

* Only execute one EoE handler per EoE cycle.

    81

* Fix datagram errors on application loading/unloading.

    82

    83

Less important issues:

    84

    85

* Allow VLAN tagging.

    86

* Determine number of frames, the NIC can handle.

    87
