Launch script with Joystick

dthgti

Hi there! i'm trying to get RetroPie installation accesed without having to use the TV remote, so... i got 2 scripts to controll tv through hdmi-cec:

1 turn on tv ((turnon.sh))
echo 'on 0' | cec-client -s -d 1

2 switch source to hdmi where the rpi is connected ((changesource.sh))
echo 'as' | cec-client -s -d 1

Ok, i've tried those scripts from console and they work, i want to execute both or just one of those, when i hit SOME KEY OF MY JOYSTICK, but i can't find any mapping app inside retropie.

I've being messing with runcommand-menu, and i got both scripts to appear in user menu, and launch those scripts from there, but i need to do that without seein the screein, just by touching keys on joystick.

some data: rpi4 4gb + 8bitdo sf30pro joystick + logitech k400 keyboard (if needed for coding but not willing to use keyboard to execute scripts) + wired ethernet + philips android tv.

Thank you in advice.

@dthgti Look-up triggerhappy - it runs as a service and listens to input events (Keyboard/Controller/etc.).

@mitu nice one! it's exactly what i'm looking for, i'll try things with that tool, will tell you later if i can make it.

@mitu i've been trying things with triggerhappy but i think it's too difficult for me, can you help me with coding?

"thd --dump /dev/input/event6"
witch this comand i found out the event of the button i want to make tv to turn on. it returns this:

"EV_KEY BTN_THUMBL 1 /dev/input/event6

BTN_THUMBL 1 command

EV_KEY BTN_THUMBL 0 /dev/input/event6

BTN_THUMBL 0 command"

so
[EV_KEY BTN_THUMBL] is event produced by button i want.
[0] is release button
[1] is push button
[2] is hold button

Knowing this, now i'm going to do what guide says:
https://github.com/wertarbyte/triggerhappy

*"Event handlers can be defined in configuration files (specified by --triggers).
If a directory is specified, all configuration files within matching the
pattern *.conf are loaded. The files use the following format:

e.g.

KEY_VOLUMEUP 1 /usr/bin/amixer set Master 5%+
KEY_VOLUMEUP 2 /usr/bin/amixer set Master 5%+
KEY_VOLUMEDOWN 1 /usr/bin/amixer set Master 5%-
KEY_VOLUMEDOWN 2 /usr/bin/amixer set Master 5%-"*

i don't know how to proceed anymore, after the example, it gives poor info, so i can't just change data and make it work. any suggestion?

i think next step is to create the .conf file, i did that, but i'm failing in content of that file, in github it says <event name> <event value> <command line> so i think correct way should be:

BTN_THUMBL 1 "HERE GOES COMAND THAT I WANT TO EXECUTE"

i don't know what comand to write there, remember that i just want to execute this script (named pushstar.sh) [echo 'on 0' | cec-client -s -d 1], so the .conf file should be like this?

BTN_THUMBL 1 ./pushstar.sh

¿?¿?¿?

@dthgti as the page says:

For more information, consult the manual pages of "thd" and "th-cmd".

You'll need to add a .conf file with the necessary lines in /etc/triggerhapy/triggers.d/.

finally i've got it done! with some minor bugs that will try to fix, but work most of the times.

one thing... all this works after i execute this:

thd --triggers /etc/triggerhappy/triggers.d/ /dev/input/event

but, how do i autostart that on every boot?

triggerhappy runs as a service when your system starts. Unless you've disabled it, it should read the configuration file and do the actions configured.
