EtherCAT master TODO

Version 1.4.0:
|
|
|
|
* Realtime interface changes:
|
|
- SDO access.
|
|
* Mailbox handler
|
|
* READMEs for examples.
|
|
* Remove get_cycles() calls and references to cpu_khz to increase
|
|
portability.
|
|
* Remove ecdb.h and let lsec output PDO information 'cut-and-pastable' for
|
|
applications.
|
|
* SDO write access in sysfs.
|
|
* Distributed clocks.
|
|
* Update documentation.
|
|
* Do not configure in ecrt_master_activate(), but later in the state machine.
|
|
* Remove master_state_t.
|
|
* Scanning of Sdo dictionary / writing EEPROM in OPERATION state.
|
|
* Adapt remaining examples.
|
|
* Separate Pdo and Pdo entry classes.
|
|
* Attach Pdo names.
|
|
* Make all define underscores the same.
|
|
* Remove bus validation; make bus scanning possible at any time.
|
|
* Re-design slave configuration FSM, avoid unnecessary process data
|
|
interruptions.
|
|
* Wait for bus scanning, even when link is not up at ecrt_request_master().
|
|
* Implement ecrt_slave_config_state().
|
|
|
|
Future issues:
|
|
|
|
* Move slave handlers and state machines, etc. into a user space daemon.
|
|
- Step 1: Replace Sysfs interface with cdev and a user space program
|
|
to replace lsec.
|
|
- Step 2: Move kernel threads to user space daemon with a TCP interface
|
|
replacing the cdev.
|
|
* Mailbox gateway.
|
|
* Slave-to-slave communication.
|
|
* Redundancy with 2 network adapters.
|
|
* Interface/buffers for asynchronous domain IO.
|
|
|
|
Smaller issues:
|
|
|
|
* Unite fsm_pdo_mapping, fsm_pdo_config and fsm_coe_map.
|
|
* Clear sync managers in INIT.
|
|
* Simplify FSMs with <state>_enter() functions.
|
|
* Read out CRC counters.
|
|
* Optimize alignment of process data.
|
|
* Evaluate EEPROM contents after writing.
|
|
* Configure slave ports to automatically open on link detection.
|
|
* Interrupt master state machines state scan for other jobs.
|
|
* Master state machine, slave configuration: Do not check every slave on
|
|
a cycle.
|
|
* Only execute one EoE handler per EoE cycle.
|
|
|
|
Less important issues:
|
|
|
|
* File access over EtherCAT (FoE).
|
|
* Allow VLAN tagging.
|
|
* Determine number of frames, the NIC can handle.
