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!
Greets, Thomas

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/

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.
