Add joy to keyboard button mapper

[tiopex]

Linux Joystick Mapper app for mapping joy/gamepad buttons to miyoo keyboard keys.

Configuration:
Provide configuration to your gamepad in file /mnt/joymap.map (as default there is configuration for xbox gamepad)
enter id or vendor and product from your gamepad (see /proc/bus/input/devices) and provide correct src numbers for buttons and axis

hint: use input_info /dev/input/event1 >>/mnt/input.log then ctrl+c to discover the correct src numbers for buttons and axis

Detailed configuration described in the attached config.pdf file

Usage:

1. Run USB host script from gmenu2x
2. Run joymap script from gmenu2x
3. Connect gamepad

Not sure yet, but it does only register 2 axis on my generic gamepad and when pressed they stay in that state even after release. Couldn't map buttons - I have read src values from jstest --event /dev/input/js0. Took me some time to realize that /proc/bus/input/devices already has values in HEX of vendor and product

Here is my config:

button vendor=0x2563 product=0x0575 src=1 target=kbd button="leftalt"
button vendor=0x2563 product=0x0575 src=2 target=kbd button="leftctrl"
button vendor=0x2563 product=0x0575 src=3 target=kbd button=""
button vendor=0x2563 product=0x0575 src=4 target=kbd button="leftshift"
button vendor=0x2563 product=0x0575 src=5 target=kbd button="space"
button vendor=0x2563 product=0x0575 src=6 target=kbd button=""
button vendor=0x2563 product=0x0575 src=7 target=kbd button="tab"
button vendor=0x2563 product=0x0575 src=8 target=kbd button="backspace"
button vendor=0x2563 product=0x0575 src=9 target=kbd button="rightalt"
button vendor=0x2563 product=0x0575 src=10 target=kbd button="rightshift"
button vendor=0x2563 product=0x0575 src=11 target=kbd button="esc"


axis vendor=0x2563 product=0x0575 src=0 target=kbd plus="right" minus="left" flags=trinary
axis vendor=0x2563 product=0x0575 src=1 target=kbd plus="down" minus="up" flags=trinary

BTW u can run loadmap joymap.map from terminal to see list of available input devices to map

[tiopex]

src values from jstest are incorrect. I've added input_info app (hint: input_info /dev/input/event1 >>/mnt/input.log then ctrl+c) to discover the correct src numbers for buttons and axis. Also added -d parameter to compute the calibration value so that events are reported in the range -32767 to 32767.

Can you check the values from axis in jstest after press and release?

[Apaczer]

Yes, the ranges are correct, but still the same issue on all axises. Buttons works correct after identyfing from input_info, so thanks for clarification.

I'll try the xdotool package with https://github.com/wizlab-it/joymap and see if I can get different outcome.

[tiopex]

I was trying joymap with xdotool, not working at all.
You can try with different flags, binary trinary min max deadzone

[Apaczer]

Success! Had to wiggle a bit settings until I found one suitable for my joystick:

axis vendor=0x2563 product=0x0575 src=0 target=kbd minus="left" plus="right" min=0 max=255 deadzone=150 flags=trinary
axis vendor=0x2563 product=0x0575 src=1 target=kbd minus="up" plus="down" min=0 max=255 deadzone=150 flags=trinary

This will be great for frontend and other apps without complex input configuration! GJ 👍

I need to rework GMenu2X to simplify executing apps in bg, now it's a pain to do from there. Additionaly joymap.sh or linkapp should treat $1 as mapping to make enduser pick between suitable configuration.

[tiopex]

I think one configuration for all will be fine, as it use product and vendor code. Like a base for all known gamepads. Can you share your config and the name of gamepad, so I will add it to the pr?

[tiopex]

Also if you add param -8 to loadmap it should transform min-max from 0 255 to -32767 32767 and deadzone shouldn't be needed

maybe we could test if /dev/input/js0 exist, if not killall loadmap
