Rocview supports up to 4 connected gamepads for controlling locomotives.
The Gamepad support must be enabled.
In case a gamepad is connected, a locomotive can be selected with function 10 which pops up the selection dialog (see below).
With the D-pad a locomotive from the list can be selected which must be activated with the function 10 button.

Dialogue Mobile selection

Predefined action mapping

Button	Action
1 to 4	decoder function 1 to 4
5	change direction
6	lights on/off
7	stop (not emergency)
8	track power off
9	track power on
10	select locomotive (dialog open/close)
D-pad	speed up/down, or scroll through the loc list

These are the predefined button definitions.
The values are zero indexed. (mapping 0 is button 1)

How to map a GamePad

After the GamePad is connected and pressing the buttons and Axis you will get messages in the trace like these:

JsEvent dev=0, type=1, number=0, value=1, msec=50766908
JsEvent dev=0, type=1, number=1, value=1, msec=50773640
JsEvent dev=0, type=1, number=2, value=1, msec=50774584
JsEvent dev=0, type=1, number=3, value=1, msec=50775384
JsEvent dev=0, type=2, number=5, value=-32767, msec=50778792
JsEvent dev=0, type=2, number=5, value=0, msec=50779824

Type 1 is a Button, type 2 are axis.

Setup in Rocview

Possible entries:

V: button used for acceleration/decelleration
Repeat: auto repeat interval in case the acceleration button is kept pressed, entry is in in msec.
- smaller numbers get higher repeat rate.
- "0" means autorepeat = off
Direction: button to change loco direction, in case it is pressed loco will: decelerate , stop, accelerate in opposite direction
Stop: button to stop the loco
Decoder steps: defines how much decoder steps are accelerated/decelerated per keypress
Lights: button to toggle lights
F1-12: button to toggle F1-F12
- -1 for not used
on/off: button to switch on/off command station power (not all command station may support this)

Trouble shooting

Try todo the following test running Linux:

open a console
connect the gamepad
type the command:

  cat /dev/input/js0
or
  cat /dev/js0

press all buttons one after another starting with button 1
press the D-Pad in all direction.

The console output should show something like this (depends on the console codepage settings):

The Gamepad is not useable if there is no output on pressing a button or D-Pad.

Now start the Rocview in a console:

./rocview -debug

insert the gamepad
touch all buttons and D-Pad direction as you did with the previouse test.

It is all a matter of mapping:

If your D-Pad generates different values like those ones: (rocview trace with debug lines)

The number corresponds to the number of the gamepad button subtracted with 1. In this example the button 1 to 4 where pressed and meets the default values in the jsmap.

Adjust the jsmap in the rocgui.ini to meet your gamepad. Example:

<jsmap step="1" updown="5" repeat="500" reverse="4" stop="6" light="5" f1="0" f2="1" f3="2" f4="3" poweron="8" poweroff="7"/>
