[How to do instruction] Using a wireless USB Keypad as remote control

[wga22]

A simple, effective, way to create a remote control for Moode is to repurpose a "wireless USB keypad".




Parts list

• Wireless USB Keypad (~$11)
  

Instructions 

1. insert USB dongle from keypad
   
2. modify /etc/triggerhappy/triggers.d/media.conf  with the content below
   
3. enable, and restart triggerhappy:
   
   systemctl enable triggerhappy
   systemctl restart triggerhappy
   

Code:

#/etc/triggerhappy/triggers.d/media.conf
KEY_KP0         0       mpc toggle
KEY_KPENTER     0       mpc next
KEY_KPPLUS      0       /var/www/vol.sh -up 5
KEY_KPMINUS     0       /var/www/vol.sh -dn 5

KEY_KP8         0       /var/www/vol.sh -up 5
KEY_KP6         0       mpc next
KEY_KP5         0       mpc pause
KEY_KP2         0       /var/www/vol.sh -dn 5

What fun. With my kids and grandkids it was all Hot Wheels cars (think jazzed-up Dinky Toys) and Lego bricks down the back of the chair. No room for fortunes.

Hello there,

i wanted to add that you can read out the keynames for your keyboard when you log in via ssh and type in the following command:

Code:

sudo thd --dump /dev/input/event0

This displays the keys that were recognized.
Exit the display via Ctrl-C.

The file /etc/triggerhappy/triggers.d/media.conf is built up as follows..


KEY_Name    Press-Action        Command

The Key_Name can be displayed via the command above,
the Press-Action is  0=release button  1= press button 2= press button long.
The command can be found in the setup-txt of MoOde. Actually, the info is in line 311 following.

Additionally, if you type in "mpc help" via ssh, this give's you the full set of possible commands.

Just a little more explanation to make it easier to follow.

Thanks for your great work!

Hi,

what Pi model and what moOde version are you on?

maybe you can also post the result of the following:

ls -l /dev/input/

Triggerhappy isnt working with me, am i doing something wrong or missing something ?

Thanks for your advise

Ok, i think i found the cause, mini keyboard is not recognized by the pi-zero.
Just attached another big size keyboard and everything works as it should.

Thanks Nutul

Hi,

I suppose you are not so happy, but nevertheless...

can you try this:
lsusb

before and after having plugged the mini kbd, so we know if it is at least seen by the system.
