Hello, I am using patchbox os which is great. What I am trying to do is to somehow use the button finctionality. I found out it is hooked to gpio17 so I did the same with my custom button, but now the thing is pisound-btn seems not starting. When run I get: “Reading Pisound serial failed, did the …

Edit the ExecStart line as: ExecStart=/usr/bin/pisound-btn --gpio 21

is it possible to change the gpio to fit with a button on my tft screen. if so where should i look. thanks

Just in case I found it there: BlokasLabs/pisound/blob/master/pisound-btn/pisound-btn.c /* * pisound-btn daemon for the Pisound button. * Copyright (C) 2017 Vilniaus Blokas UAB, https://blokas.io/pisound * * This program is free software; you can redistribute it and/or * modify it un…

I have just made pisound-btn to run even if Pisound is not detected (no config changes necessary), and added a --gpio N command line argument to specify which GPIO pin to use. It will also take care of ‘exporting’ the GPIO pin, if necessary. (Changing BUTTON_PIN would not have been enough, as Pisoun…

Thank you! I’ll test it up and report back.

Hi, I’m using Pisound and the button works just as expeced, also when I soldered an “external” button to gpio 17 and gnd. Anyway, when using Patchbox OS on RPi without Pisound, it doesn’t seem to work. I made all recomended updates, the command “–gpio N” does chande the pin and I get info that it’s…

I gave it up as it also does not work for me. Forgot to report it up.

The Pisound’s device tree overlay configures the button pin as an input pin with pull up enabled, active low mode. If Pisound is removed, the pin is not properly configured. There’s multiple ways to get this configuration done, you may write and load your own device tree overlay, use commands like r…

Thx, the trick with hooking the other end of the button to +3V3 doesn’t work with GPIO 17 but it does with GPIO 21. However, I have no frickin’ idea how to permanently change gpio to 21. What I do is typing: pisound-btn --gpio 21 and it says “Listening to events on GPIO #21” and it is listening, i…

The +3V3 trick worked for me on GPIO 17 and RPi4, but anyway, to change the pin and save it between reboots, you have to override the pisound-btn.service file. See this topic where I explain how to do it for modep-mod-ui.service, and do the same for pisound-btn.service, edit the command line appropr…
