|
|
* Truncated JMRI WiThrottle server implementation for DCC-EX command station
|
|
* Credit is due to Valerie Valley RR https://sites.google.com/site/valerievalleyrr/
|
|
* for showing how it could be done, but this code is very different to the original
|
|
* implementation as it is designed to run on the Arduino and not the ESP and is
|
|
* also calling directly into the DCCEX Api rather than simulating JMRI text commands.
|
|
* Refer JMRI WiFi Throttle Communications Protocol https://www.jmri.org/help/en/package/jmri/jmrit/withrottle/Protocol.shtml
|
|
*
|
|
*
|
|
* PROTOTYPE NOTES:
|
|
* There will be one WiThrottle instance created for each WiThrottle client detected by the WifiInterface.
|
|
* Some shortcuts have been taken and there are some things that are yet to be included:
|
|
* e.g. Full response to adding a loco.
|
|
* What to do about unknown turnouts.
|
|
* Broadcasting to other WiThrottles when things change.
|
|
* - Bear in mind that changes may have taken place due to
|
|
* other WiThrottles, OR JMRI commands received OR TPL automation.
|
|
* - I suggest that at the end of parse(), then anything that has changed and is of interest could
|
|
* be notified then. (e.g loco speeds, directions or functions, turnout states.
|
|
*
|
|
* WiThrottle.h sets the max locos per client at 10, this is ok to increase but requires just an extra 3 bytes per loco per client.
