[ANNOUNCE] SqueezeButtonPi - Tool to use buttons and rotary encoders on a RPi

[Paul Webster]

No

You do it all from the pCP web interface - look for "Extensions".


Note though ... pCP is not like other Linux systems.
It is great for novices to get going really quickly.
Part of its speed in booting is its small size and being memory resident.

However, if you want to do something that it does not handle already then it can be harder to do then you would expect from a generic How To guide that is aimed at Rasbian or Raspberry Pi OS ... as you are finding out.

You might be better off using a full Linux and then following a generic guide for installing LMS and Squeezelite ... then you can more easily add other things where you follow a generic guide.

I did everything with Termina!!!!
Now I used Extensions!

It seems better but not working:

"Could not connect to pigpiod. Is it running?"

This does not look good.
Is it running?

ps -ef | grep pigpiod

[chill]

You have to start the pigpio daemon manually before running sbpd. See this post for an example script.

But nothing happens when PIN24 (GPIO8) goes to GND

[paul-]

Then tell it to use pin 8, it’s all in the help information.

For buttons: 
    b,pin,CMD[,resist,pressed,CMD_LONG,long_time]
        "b" for "Button"
        pin: GPIO PIN numbers in BCM-notation

Almost nothing uses physical PIN numbers.

[chill]

What command line options did you use with pigpiod?
Do you have any other devices attached to this RPi?

It work!!! I used physical pin numbers! :-(

But when I quit (CTRL C) the terminal, the switch doesn't work anymore.
How to "stay" it working ?

- Is there 6 commands (pause, vol up/dn, rew, ffw and power) available ?

Thanks

[Paul Webster]

You need to set it to run automatically on boot - see the linked posts for how to get pCP to do that for you.

I look on the post and create file sbpd-script.sh

#start pigpiod daemon
sudo pigpiod -t 0 -f -l -s 10

# wait for pigpiod to initialize - indicated by 'pigs t' exit code of zero
count=10 # approx time limit in seconds
while ! pigs t >/dev/null 2>&1 ; do
        if [ $((count--)) -le 0 ]; then
                printf "\npigpiod failed to initialize within time limit\n"
                exit 1 # or however you want to deal with failure
        fi
#       printf "\nWaiting for pigpiod to initialize\n"
        sleep 1
done
printf "\npigpiod is running\n"

# load uinput module - required to be able to send keystrokes
# then set the permission to group writable, so you don't need to run sbpd with
sudo modprobe uinput
sudo chmod g+w /dev/uinput

# issue the sbpd command
sbpd -s b,8,PLAY,2,0 -v

And added on the Tweaks User command #1 /home/tc/sbpd-script.sh

But something more is missing.

[chill]

But something more is missing.

Why? You'll have to explain what's happening now.

Did you make the script executable?
Did you test it from the command line?

[PaulH]

I made:
chmod g+x sbpd-script.sh

I can't run it:

[email protected]:~$ [email protected]:~$ sbpd-script.sh
-sh: sbpd-script.sh: not found

The file exist

[email protected]:~$ ls
pcp-powerbutton.sh  powerscript.sh      sbpd-script.sh

[Paul Webster]

sh sbpd-script.sh

or put a "hash bang" on the first line

#!/bin/sh

Also - make sure that you are using Unix line-endings for the file
If you made all of your edits with nano or vi then you will be ok.
If you did it with Notepad on Windows then you might have problems.
If you are using Windows then Notepad++ is the 3rd-party tool to use and tell it to save in Unix format.

- Is there 6 commands (pause, vol up/dn, rew, ffw and power) available ?

Yes, built in, but there is almost an infinite amount of possibilities with custom configuration files.....its all buried in this thread. But get one thing working correctly so you understand, before moving onto more.

[chill]

I can't run it:

[email protected]:~$ [email protected]:~$ sbpd-script.sh
-sh: sbpd-script.sh: not found

Ah, that's an evil Linux trap for the unwary Windows user! It won't assume that you are referring to a file in the current directory. You have to be explicit:

[email protected]:~$ [email protected]:~$ ./sbpd-script.sh
