Version 1.5.0:

    12

    13

* Fix link detection in generic driver.

    14

* Remove byte-swapping functions from user space.

    15

* Implement 'ethercat foe_read --output-file ...'.

    16

* Use ec_datagram_zero() wherever possible.

    17

* Fix arguments of reg_read.

    18

* Number layout for reg_read.

    19

* Finish library implementation.

    20

* Rescan command.

    21

* Document ec_fsm_foe members.

    22

* Implement identifier parameter for cstruct command.

    23

* Implement sync delimiter for cstruct command.

    24

* Change SDO index at runtime for SDO request.

    25

* Output skipped datagrams again.

    26

* Output warning on unmatched slave configuration.

    27

* Output warning when send_ext() is called in illegal context.

    28

* Output hexadecimal values in 'ethercat xml'.

    29

* Add native drivers from 2.6.24 up to 2.6.31.

    30

* Implement indent in 'ethercat ma'

    31

* Add master index to log messages.

    32

* Implement 0xXXXX:YY format for specifying SDOs.

    33

* Lookup codes for 64bit data types.

    34

* Move data type usage string into DataTypeHandler.

    35

* Implement interpretation of SoE '[SP]-x-yyy' strings.

    36

* Implement reading from stream for soe_write.

    38

    39

Future issues:

    40

    41

* Implement ecrt_slave_config_request_state().

    42

* Implement CompleteAccess for command-line tool.

    43

* Implement CompleteAccess for SDO uploads.

    44

* Check for Enable SDO Complete Access flag.

    45

* Remove default buffer size in SDO upload.

    46

* Improve application-triggered SDO transfers by moving the state machine into

    47

  the SDO handlers.

    48

* Remove allow_scanning flag.

    49

* Override sync manager size?

    50

* Show Record / Array / List type of SDOs.

    51

* Distributed clocks:

    52

    - Check 32/64 bit operations.

    53

    - Use vendor correction factors when calculating transmission delays.

    54

    - Skip setting system time offset when application detached.

    55

    - How to use the SYNC1 shift time?

    56

    - Do not output graph, if topology calculation failed.

    57

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

    58

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

    59

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

    60

      configuring.

    61

* Mailbox protocol handlers.

    62

* Mailbox state machine using toggle bits.

    63

* External memory for SDO transfers.

    64

* C++ implementation of the library.

    65

* Bus simulator interface.

    66

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

    67

  space daemon.

    68

* Allow master requesting when in ORPHANED phase

    69

* Mailbox gateway.

    70

* Separate CoE debugging.

    71

* Evaluate EEPROM contents after writing.

    72

* Optimize alignment of process data.

    73

* Redundancy with 2 network adapters.

    74

* Interface/buffers for asynchronous domain IO.

    75

* Make scanning and configuration run parallel (each).

    76

* ethercat tool:

    77

    - Data type abbreviations.

    78

    - Add a -n (numeric) switch.

    79

	- Check for unwanted options.

    80

    - Implement ranges for slaves, domains, etc.

    81

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

    82

  requests (replace write_sii, sdo_request, etc).

    83

    84

Smaller issues:

    85

    86

* Read out CRC counters.

    87

* Configure slave ports to automatically open on link detection.

    88

* Fix datagram errors on application loading/unloading.

    89

    90

Less important issues:

    91

    92

* Allow VLAN tagging.

    93

* Determine number of frames, the NIC can handle.

    94
