Gpio pins not working on pi 5

[TNT]

Hello good people of the Volumie community can anybody help with this?

Problem with Gpio on my Raspberry pi 5 8 gb. Not alle of them are working. Only the Ir remote is working and now also a error that says Alsa fail to open Alsa device.

All work perfect on a raspberry pi zero 2.

With my Dac Dragonfly Red

I bought a raspberry pi 5 in march, It was my first raspberry pi build, I am new to all thinks with the raspberry pi. But i was gonna build streaming pi using volumio software. And I did, and put it in a case, not using the gpio pin. It worked okay but, with some small errors I thought maybe was settings, that i had to check up on.

After a couple of weeks i wanted to expand the streamer,

with Buttons, Oled Display, Ir remote, 2 Led lights, rotary encoder and power Butten

So i bought a pi zero 2 and a breadboard and slowly build a better version of the streamer. Testing it on the zero.

But when I had to assembled it all in a new case, I found out, that some of the gpio pins doesn’t work on the raspberry pi 5 it works great on the pi zero 2 and some of the other problems I had on the pi 5 was working on the zero.

I got a new pi 5 from the place I got it, thinking it must be a faulty unit. But still same problem came up.

Not connection to

Oled Display, buttons, power button on gpio 3 not working. And one of the led light doesn’t work

Not tested the rotary encoder, because of the other problem.

I tried.

Fresh install a lot of times and install from website, install of raspberry pi software to upgrade system.

And screaming ad it

Can anybody help with this.

Ps, I am new to this.

Raspberry Pi 5 Notes

• There are dedicated pads on the PCB for connecting an external switch.
  

• On Buster V3.819, the following components work flawlessly:

  • OLED displays (3,3V VCC, GND, SDA, SDL)
  • GPIO buttons
  • GPIO-controlled LEDs (gpio=12,16,20)
  • Rotary encoders (3,3V VCC, gpio=5,6,22 and gpio=17,27, powerswitch pad)

• If something isn’t working:

  • Double-check your wiring setup
  • Make sure you’re not exceeding the power capacity of your PSU,you’re using the official 25.5W Raspberry Pi power supply?

I am running a rPi5, with 2 rotary encoders, power switch, power led and 2.42 Inch OLED display.

nice set up.
i have the official 27 W Raspberry Pi power supply is there at difference from that to the 25.5 w
one off the led light are Connected to the gpio 16

[Wheaten]

Try gpio=12 for the led

What plug in are you using to get this information on a 2.42" OLED display?

I have a 2.42" SPI OLED display and an MPD OLED plug-in.

But I’m interested in your version of displaying information on a 2.42" OLED.

[Wheaten]

This is something I programmed for personal use only.

[tweed77]

Could you elaborate on how to do this?
What needs to be edited to change the display method?
Is this done in the configuration files in the MPD OLED plugin?

[Wheaten]

It’s completely written in Python, it has nothing in common with MPD_OLED.
Information is extracted by calling:

# Fetch Volumio status
def get_volumio_status(host="http://localhost:3000"):
    try:
        response = requests.get(f"{host}/api/v1/getstate")
        if response.status_code == 200:
            return response.json()
    except Exception as e:
        print(f"[Volumio Error] {e}")
    return {}

# Fetch MPD audio info
def get_mpd_audio(host="localhost", port=6600):
    try:
        with socket.create_connection((host, port), timeout=5) as s:
            s.recv(1024)
            s.sendall(b"status\n")
            data = s.recv(4096).decode()
            audio = re.search(r'audio:\s*(\S+)', data)
            bitrate = re.search(r'bitrate:\s*(\d+)', data)
            return audio.group(1) if audio else "Unknown", int(bitrate.group(1)) if bitrate else 0
    except Exception as e:
        print(f"[MPD Error] {e}")
    return "Unknown", 0

To me, this is black magic
Unless someone explains it to me in layman’s terms…
If this could be edited in the MPD OLED plugin configuration file, I could still manage it.
Thanks for the information.
