9 * Future features: |
9 Version 1.4.0: |
10 - Distributed clocks. |
|
11 - Redundancy with 2 network adapters. |
|
12 - Mailbox handler |
|
13 - Support slaves, that don't support the LRW datagram, only LRD/LWR. |
|
14 - PDO reading in IDLE mode. |
|
15 - Replace Sysfs interface with cdev and user space program. |
|
16 - Interface/buffers for asynchronous domain IO. |
|
17 - Remove ecdb.h and let lsec output pdo information 'cut-and-pasteable' for |
|
18 applications. |
|
19 - SDO access via realtime interface. |
|
20 - Scanning shall include reading the PDO mapping via CoE. |
|
21 |
10 |
22 * Smaller issues: |

23 - Datagram debugging flag. |
12 - PDO configuration. |
24 - Clear sync managers in INIT. |
13 - SDO access. |
25 - Simplify FSMs with <state>_enter() functions. |
14 - Replace process data pointers with offset. |
26 - Output intermediate results during lsec. |
15 - External memory for domains. |
27 - Read out CRC counters. |
16 * Mailbox handler |
28 - Calculate expected working counter for domains. |
17 * Read PDO mapping via CoE during bus scan. |
29 - Optimize alignment of process data. |
18 * SDO write access in sysfs. |
30 - Evaluate EEPROM contents after writing. |
19 * Remove get_cycles() calls and references to cpu_khz to increase |
31 - SDO write access in sysfs. |
20 portability. |
32 - Configure slave ports to automatically open on link detection. |
21 * Remove ecdb.h and let lsec output PDO information 'cut-and-pastable' for |
33 - Calculate cycle time of operation state machine. |
22 applications. |
34 - Locking for serveral slave variables for sysfs access. |
23 * Update documentation. |
35 - Interrupt master state machines state scan for other jobs. |
|
36 - Master state machine, slave configuration: Do not check every slave on |
|
37 a cycle. |
|
38 - Only execute one EoE handler per EoE cycle. |
|
39 |
24 |
40 * Less important issues: |
25 Future issues: |
41 - Implement all EtherCAT datagram types. |
26 |
42 - File access over EtherCAT (FoE). |
27 * Move slave handlers and state machines, etc. into a user space daemon. |
43 - Allow VLAN tagging. |
28 - Step 1: Replace Sysfs interface with cdev and a user space program |
44 - Determine number of frames, the NIC can handle. |
29 to replace lsec. |
|
30 - Step 2: Move kernel threads to user space daemon with a TCP interface |
|
31 replacing the cdev. |
