Issues with I2C/GPIO 2 and 3
I'm having issues with I2C-1 on a Pi 4 model B. The pins stay high, no matter what I do (verified using a logic analyser). I know about the pull-ups, so it makes sense that they are high on boot. I've tried following:
- Switched to a different PI (same model)
- Tried a different PSU
- Disconnected everything from the GPIO header
- Used pinctrl to set GPIO2 and GPIO3 manually. They stay high
- Other GPIO's do work as expected
- Reflashed SD card with clean raspbian
Anyone any idea what to try next? I'm out of ideas

does anyone know what this component this is and its value? (smd component RPi 4B)
Rpi 4b green light wasn't blinking. sd card was fine, so I checked the back and it has this component missing. not sure if its a capacitor or a resistor. I have it boxed in the image attached. as far as I know this is what is stopping it from working 🤷♂️

source file/bin/activate
python file/main.py
i tried adding those commands to crontab hoping it'd work but it does not
@reboot source file/bin/activate &

i am fairly new to this and i just followed youtube so far to set stuff up. anyone know how to get my main.py file running on reboot?

sta+ap Wifi mode and dnsmasq dns + dhcp setup
Hello, for a project, I wanted to be able to connect to a website hosted by my Pi 4, get a ip address via dnsmasq dhcp server and tunnel some domains (like server.lan to 127.0.0.1) while being connect to a host network to communicate to the world wide web. I have found guide for all of these separately, but those didn't work, even separately.

RPI Zero W using USB ethernet via my PC
Hello, My RPI Zero W I had setup by adding a new line in config.txt and adding the stuff I needed to and also in cmdline.txt and created a file just called ssh, no extensions. I plugged my RPI into my pc via a micro usb cable to connect and I used the data port. My PC shows the ethernet and it connecting but whenever I do ping raspberrypi.local or try ssh to it, it says it doesn't recognise it, I'm using a 64gb micro sd card formatted for FAT32, the green light is showing on the RPI but I'm not sure what to do. Thank you

Raspberry Pi 4 B can't ping or use ssh after installing raspio_arm64_lite
Hi, I'm very new to raspberry pi. I used PINN and vncshare to install raspio lite. After the os was installed, vnc loses connection. After that I cannot seem to ping the ip address of the Rpi, it isn't on the wifi client list either.
I've reformatted the sd card and reinstalled raspio lite twice which haven't worked.
I am following this guide https://gitlab.com/public-open-source/spotmicroai/basic-instructions/-/tree/master/1.%20Prepare%20your%20RaspberryPi?ref_type=heads
Any help is greatly appreciated!

[zero-w] Debug constant crashes
Hello everyone, i have come to yall as my last resort. My rapsberrypi zero-w just keeps crashing(?) every few days and i cannot figure out the cause or how to stop it.
Ist running a simple discord.py bot that is supervised by the pm2 process manager. Every 1-3 Days it goes offline and refuses to do literally anything. I cannot interact with it via cable or ssh. After having to cut power [:(] to get it back running i tried sifting through journalctl but with no luck. After observing when exactly it went offline, then going back and checking that timestamp there is literally nothing logged at that time.
I have tried completely whiping it and reinstalling the OS, didnt help. I have tried the watchdog (though admittely i had no idea what i was doing really). No luck.
It is a new bought rapsbverrypi zero-w running pi-OS (not headless). Ive had the issue whether i primarily connect to it via hdmi and keyboard or ssh.
Any Ideas how i could go about debugging this will be apppreciated 🙂

Pi 4: Raspbian booting to commandline, instantly logs me out
I've been getting my brand new Raspberry Pi 4 set up, and I installed Raspbian on it. However, after rebooting, it now only boots to the commandline login instead of the desktop login...
and when I type in my username and password, it seems to log-in, but then instantly boots me back to the same commandline.
How can I go about troubleshooting this?

Raspberry Pi 5 and MLX90640 Adafruit sensor connection with SSH at the moment but should change
Hi, I have successfully connected my sensor and Pi using SSH. I set up the Raspberry Pi OS on my SD card and ran the code in VS and it works. My next steps are to connect my sensor and display an image for real time monitoring and data acquisition using LabVIEW for the GUI.
I don't want to rely on using Wi-fi for my project and my Pi might loose connection with the internet so what are my other options to connect my Pi because that will determine how I design my GUI in LabVIEW?
I am new to Pi so I am struggling a bit. People said you can use external mouse and keyboard to access the Pi GUI but what if I just want the Pi connected to run the code saved in it and have my own GUI but not suing wifi?
Is the mouse and keyboard the only way of connection?

Raspberry Pi 4 and OpenMediaVault
Hello,
I am currently in the process of setting up a NAS system with OpenMediaVault on my Raspberry Pi 4B. When I execute the install script from OpenMediaVault, everything works fine. At the end, it says that everything has been successfully created, and then the script restarts my Raspberry Pi:
yaml Succeeded: 13 (changed=8) Failed: 0 ------------- Total states run: 13 Total run time: 3.513 s [2024-02-11 13:35:19+0100] [omvinstall] Network setup. Rebooting...I get kicked out of my SSH session. However, I cannot reconnect afterward. On my router, I can see that the Raspberry Pi is connected to the Wi-Fi network. However, I cannot access the OpenMediaVault page, and I cannot connect via SSH. When I ping the Pi (using the Ping command in the Windows cmd):

Is it Possible to trigger gaming pcs power button when raspberry pi loses and gains power?
I am building an arcade cabinet and I was wondering if I could have a raspberry pi hooked up to a power source that has a wireless outlet to remotely turn it off and on and make it power off and power on my pc when power is applied to it
Kind of a specific issue but i don’t really know where to start
Was thinking something like a Zero W so maybe I can wirelessly turn it off too

I Want to create a Music player from voice command , help
So basically we are told to create any project using raspberry pi in our college. I have great project idea that is we'll be creating a music player from voice command. I have created discord music bots using node.js so I'll be using the same method in this project as well with google transcript packages for catching the command from microphone. Whenever the user says play song_name the code will execute and fetch the music from youtube ( using ytdl ans ytsr packages in nodejs ) and it'll then send gpio signals which will result into playing the song from the speaker.
We are getting Rpi 3 B+ from college will that work ?
Basically , this is my first time creating any project in raspberry pi am i doing any mistake till now ? Also i want to create a online model of this project where can i do the same ?
Additionally this project is not available on youtube or any other platform ( as of my knowledge ) can someone list the components that I'll be needing i tried chat gpt but indeed its ai and folks here a well experienced.
Any guidance apart from these is welcomed

Can't read analogue sensor data
Hi, I'm trying to read data from the Sparkfun sound detector over SPI but for some reason it only works when I try to read the digital output (whether sound is detected or not), rather than the analogue outputs (amplitude and audio).
I'm reading it through a MCP3008 by sending 0x80 (channel 0). It returns a value when it's plugged into the GATE pin and I'm making noise, but I just get 0x00 back when I plug it into the other 2 pins. Any ideas on why? I thought the MCP was meant to convert analogue to digital so the Pi can read it.

Bluetooth as audio input "microphone"
Hello, i was wondering if it would be possible to use my raspberry pi as a bluetooth host, which i can connect to via my phone or pc and then on my raspberry pi the bluetooth audio is being recorded inside a python script using pyaudio. For this the part where i struggle is how i can setup my raspberry pi to serve as a bluetooth host and use the incomming audio signal as a microphone source.
