Version 1.5.0:

    12

    13

* Distributed clocks:

    14

    - Use common application time offset when setting start times.

    15

    - Check 32/64 bit operations.

    16

    - Set system time offset only when application time available.

    17

    - Use vendor correction factors when calculating transmission delays.

    18

* Fix unloading problem of ec_e100 driver.

    19

* Use ec_datagram_zero() where possible.

    20

* Fix arguments of reg_read.

    21

* Sign/Abs type for reg_ commands?

    22

* Number layout for reg_read.

    23

* Show Record / Array / List type of SDOs.

    24

* Limit bandwidth of state machine datagram.

    25

* Read alias from register 0x0012 instead of SII.

    26

* Finish library implementation.

    27

* Re-work EoE code.

    28

* Replace locking callbacks.

    29

* Implement EoE callbacks for library.

    30

* Rescan command.

    31

* Override sync manager size?

    32

* Remove ecrt_domain_state()?

    33

* Check force_config flag before error.

    34

* Remove allow_scanning flag.

    35

* Test File access over EtherCAT (FoE) reading.

    36

* Implement ecrt_master_slave() in kernel space.

    37

* Check for ioctl() interface version.

    38

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

    39

  the SDO handlers.

    40

* Apply watchdog patches from J. Mohre.

    41

    42

Future issues:

    43

    44

* Segmented SDO downloads.

    45

* External memory for SDO transfers.

    46

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

    47

* C++ implementation of the library.

    48

* Bus simulator interface.

    49

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

    50

  space daemon.

    51

* Allow master requesting when in ORPHANED phase

    52

* Mailbox protocol handlers.

    53

* Mailbox state machine using toggle bits.

    54

* Mailbox gateway.

    55

* Separate CoE debugging.

    56

* Evaluate EEPROM contents after writing.

    57

* Optimize alignment of process data.

    58

* Redundancy with 2 network adapters.

    59

* Interface/buffers for asynchronous domain IO.

    60

* Make scanning and configuration run parallel (each).

    61

* ethercat tool:

    62

    - Data type abbreviations.

    63

    - Add a -n (numeric) switch.

    64

	- Check for unwanted options.

    65

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

    66

  requests (replace write_sii, sdo_request, etc).

    67

    68

Smaller issues:

    69

    70

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

    71

* Clear sync managers in INIT.

    72

* Read out CRC counters.

    73

* Configure slave ports to automatically open on link detection.

    74

* Only execute one EoE handler per EoE cycle.

    75

* Fix datagram errors on application loading/unloading.

    76

    77

Less important issues:

    78

    79

* Allow VLAN tagging.

    80

* Determine number of frames, the NIC can handle.

    81
