Version 1.4.0: |
547 | 10 |
|
864 | 11 |
* Slave config allow flag and completion object. |
866 | 12 |
* Mailbox state machine using toggle bits. |
13 |
* Mailbox protocol handlers. |
|
819 | 14 |
* READMEs for examples. |
776 | 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. |
|
819 | 19 |
* SDO write access in sysfs. |
831

|
20 |
* Distributed clocks. |
776 | 21 |
* Update documentation. |
833 | 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. |
|
845 | 25 |
* Adapt remaining examples. |
848 | 26 |
* Separate Pdo and Pdo entry classes. |
27 |
* Attach Pdo names. |
|
850 | 28 |
* Make all define underscores the same. |
855 | 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(). |
|
857 | 33 |
* Implement ecrt_slave_config_state(). |
547 | 34 |
|
776 | 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. |

|
43 |
* Slave-to-slave communication. |
776 | 44 |
* Redundancy with 2 network adapters. |
45 |
* Interface/buffers for asynchronous domain IO. |
|
46 |
||
47 |
Smaller issues: |
|
48 |
||
866 | 49 |
* Evaluate SII Size field (0x003E) to determine maximum SII memory size. |
833 | 50 |
* Unite fsm_pdo_mapping, fsm_pdo_config and fsm_coe_map. |
776 | 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. |
