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

[armaster]

Hi,

I loaded extension pcp-sbpd.tct and set rotary encoder to works. This is my command:
sbpd -v e,27,17,KEY:KEY_VOLUMEUP-KEY_VOLUMEDOWN,1 b,22,KEY:KEY_POWER,2

But it seems that rotary encoder mode (Detent mode) does not work. I can change values from 1 to 9 but the same result.

I found two different repositories from git:
1. github.com/coolio107/SqueezeButtonPi-Daemon
2. github.com/paul-1/SqueezeButtonPi-Daemon

What I'm doing wrong here? Do I have right extension which supports detent mode or is repository #2 as different extension?

Where did you get the extension from? If you downloaded from our repo (With either pCP 6 or pCP 7) then it's the correct version. My repo is the version that I use for pCP.

I loaded pcp-sbpd.tcz from piCorePlayer main repository via web interface of pCP 7. This is the extension info:

Title: pcp-sbpd.tcz
Description: SqueezeButtonPi
Version: 3.0.1
Authors: Joerg Schwieder
Original-site: https://github.com/coolio107/SqueezeButtonPi-Daemon
Copying-policy: GPLv3
Size: 20k
Extension_by: piCorePlayer team: https://sites.google.com/site/picoreplayer
Compiled for piCore 10.x

This seems to be wrong one?
I checked also piCorePlayer mirror repository and Official piCore repository but didn't find github.com/paul-1/SqueezeButtonPi-Daemon.

How can I load github.com/paul-1/SqueezeButtonPi-Daemon extension from pCP web interface?

The extension is right, I used to push all of my changes to The main branch.....I should update the info file.

3.0.1 is the latest version.

Start with debUg output and then turn your encoder. Post the output.

Struggling with SqueezebuttonPi now..

Added this to the startup commands:

pigpiod -t 0; sbpd b,25,PLAY

(-t 0, because I am using a HifiBerry DAC)

But this doesn't work. When I manually start it in a shell, it does work though..:

tc@piCorePlayer:~$ sbpd b,25,PLAY

So I'm a little puzzled and I don't seem to find anything in the log files.. Any suggestions?

[jeroen2]

Solved it. Simply adding a pause between starting pigpiod and spbd made it work.

Added these lines to my startup.sh:

#start squeezebuttonpideamon
/usr/local/bin/pigpiod -t 0
sleep 1
/usr/local/sbin/sbpd -d b,25,PLAY

Thanks to Aki7 in this posting.

Sometime ago the following script was posted to start sbpd and pigpiod which is a bit more elaborated compared to Aki7's code:

#!/bin/sh

# start pigpiod daemon
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 root permissions
sudo modprobe uinput
sudo chmod g+w /dev/uinput

# issue the sbpd command
sbpd -z -d -f /home/tc/sbpd/sbpd_commands.cfg b,17,FAV1 b,27,FAV2 b,22,FAV3 b,18,FAV4 b,23,FAV5 b,24,FAV6

It is working fine in my case with Hifiberry HAT.

Thanks, I might try that later.

(I installed this while also doing an upgrade in hardware and upgrading to pCP7 and LMS8, which was leading to all kind of frustrating issues. For now decided to roll back all, and will try again in smaller steps.. But bookmarking this one)

I'm using detent value 5 but does not work. Shouldn't detent value change volume for 5 steps?

Hi

So I am trying to get my pHAT BEAT working with SqueezeButtonPi. I can get the buttons working by using the script here, https://forums.slimdevices.com/showt...=1#post1004820.

However my problem is trying to use the onboard LEDs at the same time.

I am using this code:

import phatbeat

phatbeat.set_clear_on_exit(False)

for channel in (0,1):
phatbeat.set_pixel(0, 255, 0, 0, 0.1, channel=channel)

phatbeat.show()

After running it the buttons seem to no longer working. Re-running the sbpd script (i.e. calling pigpid and then sbpd and assigning functions to gpios) fixes the problem.

Is the issue that phatbeat.py has the line Import Rpi.GPIO as GPIO?

Thanks in advance.
