Support of 28 Speed Steps about wifred HOT 6 OPEN

Throttle Commands >> 's' set speed step mode.

:) I'd hope it's the same as these: https://www.jmri.org/help/en/package/jmri/jmrit/withrottle/Protocol.shtml#ThrottleChangeNotification

(though I don't know what 27 speed steps is)

from wifred.

I just double checked the wiThrottle protocol specs and actually there is a command to set the speed step mode in the protocol already.

I'll look into it, though I won't be able to test on anything else beside JMRI.

I did not find this. Any Hint?

I will test it from throttle to loco. I have DCS100 and Loco with LE103 (or DCC Sniffer) for this.

Second try:

Still the question which values are allowed.

Older Dekoders from Lenz (LE075 or Roco 10741) supported only 14 and 27 speed steps. 27 was like 14, but the CU was sending two different speed steps alternating. http://www.dcc-mueller.de/decoder/dectab_o.htm

About guessing the values:

JMRI has a class (enum) jmri.SpeedStepMode. The ordinal values would be 0=UNKNOWN, 1=NMRA_DCC_128, 2=NMRA_DCC_28, 3=NMRA_DCC_27, 4=NMRA_DCC_14, 5=MOTOROLA_28, 6=TMCC_32, 7=INCREMENTAL.

That does not match what is documented in ThrottleChangeNotification.

https://www.jmri.org/JavaDoc/doc/src-html/jmri/SpeedStepMode.html
https://www.jmri.org/JavaDoc/doc/jmri/SpeedStepMode.html

May be a hint is the method decodeSpeedStepMode() in jmri.jmrit.withrottle.ThrottleController:
https://www.jmri.org/JavaDoc/doc/src-html/jmri/jmrit/withrottle/ThrottleController.html#line.734

So I would guess that possible values are

• "1",
• "2"
• "4"
• "8"
• "16"

and

• "unknown"
• "128"
• "28"
• "27"
• "14"
• "motorola_28"
• "tmcc_32"
• "incremental"
