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

[paul-]

Power on/off in the spbd/lms context is just turning off the "Player Power" Just like hitting the power button on the LMS interface. Most would use it to control a relay that powers an amplifier on/off.

To shutdown the complete pi, you could script it here with spbd, but other ways are easier.

Yes, I understand that this is only a "soft" power off. And this is exactly what I need. But it has an issue.

My configuration:

RPi 2B
PCP 6.1.0
pcp-sbpd
jivelite (Waveshare 3.5")

/home/tc/sbpd-script.sh
================================================== ===========================
#!/bin/sh

# start pigpiod daemon
pigpiod

# give the daemon a moment to start up before issuing the sbpd command
sleep 1

# load uinput module, 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 e,6,12,KEY:KEY_UP-KEY_DOWN,2 b,5,KEY:KEY_RIGHT,2,0,KEY:KEY_LEFT,500
================================================== ============================



Rotary encoder working...key up and down, and button also working.
BUT. when key up, down..jump 2 step down or up.
I have to rotate very slowly to move 1 step.

Does any options are available to fix this problem ?

Check the optional mode setting for encoders.

For rotary encoders (one, volume only):
    e,pin1,pin2,CMD[,edge]
        "e" for "Encoder"
        p1, p2: GPIO PIN numbers in BCM-notation
        CMD: Command. one of. \n\
            VOLU for Volume\n\
            TRAC for Prev/Next track\n\
            KEY:<Positive key_name>-<Negative key_name>
        mode: Optional. one of\n\
            1   - Step mode (default)\n\
            2-9 - Detent mode - Assumes 1 dial click is x steps.

It works after changing dent mode setting from 2 to 4.
Thank you.

The above issue is solved by LMS update to latest. Now I have a working solution to control GPIO when the player is in "power off" status.

Hi,
I'm using a PiCorePlayer v6.1 setup with HDMI output. LMS is running on Synology NAS in the LAN.
I installed the sbpd as explained on the first site of this thread.
Then I tried several hours a bunch of different User commands in the tweaks menu to get my rotary encounter running. It's a model KY-040 encounter.

First I tried to use VOLM but read later on that it got replaced by VOLU.
My last version I tried was:

/usr/local/sbin/sbpd -d -s e,23,24,VOLU,1 b,25,POWR,1

This and all the versions before didn't work.
Last thing i did was to connect via SSH and to exec:

sbpd -v e,23,24,VOLU,1

The result was:
1601829442.7315 6 GPIO.c,219:Initializing GPIO
wiringPiISR: Can't find gpio program
wiringPiISR: unable to open /sys/class/gpio/gpio23/value: No such file or directory

I assume there is a piece of software missing to use the gpio but have no clue how to solve it.

Got anybody the KY-040 running and can help me?

[meq123]

Do you have the gpio library loaded? (pigpio.tcz on the Extensions tab)

[klothi]

These were not not installed. I installed all 3 now. pigpio.tcz, pigpio-dev.tcz and pigpio-doc.tcz.
After a reboot nothing changed.
The error message is still the same. :-(

[Paul Webster]

From the error message I guess that you need wiringpi.tcz
