Raspberry Pi 4 Performance Issues: Slowdowns and Freezes, Motion Detection Software
Hello 👋 I am using a Pi 4 4GB , Pi Camera V2, powered through a standard electrical outlet, running the Bullseye 64-bit image to implement motion detection software using Code::Blocks, OpenCV, C++ and GStreamer. However, the Raspberry Pi is extremely slow, suffering from delays and freezes. It becomes challenging to implement the motion detection software and add features, especially since the camera freezes as well. Overclocking is currently not an option and it even seems i dont have the option under settings. It wont let me overclock at all. <:confusedblob:1053364681575776276> I access the Pi through VNC, and I'm not sure if the performance issues are related to that, as I don't encounter any problems when working on my job tasks via VMWare. What could I do, and what might be the problem?

Pi 5 Low Power - Anker 747 Charger (GaNPrime 150W)
I'm getting a message that the Anker 747 Charger (GaNPrime 150W) is not able to provide 5V 5A power. Anyone else have this issue? Is there a recommended power supply that can power multiple (3+) Raspberry Pi 5's?

Pi 5 USB Boot is clunky
Flashing USB Boot SD card does nothing and it still boots from SD Card, remove the SD Card with only USB and the Pi idles, going into raspi-config on the sd card setting Boot Order to usb and then rebooting finally boots to the USB, if I reboot, it still boots into the usb and works flawlessly but the moment I shut it down and start it again, it will start to boot into the SD Card or idle without it.... Latest raspi-config and bootloader and checked wtih 2 usb drives, even USB 2.0, used rpi imager and official img, balena etcher, ubuntu server and raspbian, is anybody else having this issue or is it just that I am dumb?

new to linux and pi, trying to flip my display (not rotate or invert) please help ;-;
I'm using a pi4 to drive a media installation where the image of the monitor is meant to reflect off of a pane of glass, this means that the display is inherently flipped (vertical orientation is correct but text is backwards).
As far as I can tell, the orientation settings in preferences include "left, right, normal, inverted," none of which are what I'm looking for. It also seems that any attempts to add "rotate_display=0x10000" to the
/boot/config.txt have no effect after saving and rebooting.
I'm thoroughly stumped and could use some assistance.

Pi zero / 5 inch screen help
Would anyone know how to set this touchscreen i recently ordered up? When i boot it on with my pi zero it shows the start up screen just fine but then it just shows a fading in and out white screen after that. The screen works fine with my laptop so im just confused why it only shows the start up screen with the pi zero.

Having trouble building C++ on Windows
Hello,
Somewhat new here to Raspberry Pi, but I have several years of C++ experience.
I'm on Windows and used the official installer that setup up VS Code for the Pico. A quick question:
VS Code seems to have problems with the Debug Probe. I got it to debug my program once. But then it threw out some error about hardware breakpoints and now every time I try and launch the debugger I get a OpenOCD quit unexpectedly error. The console shows these errors:
Error: could not get configuration descriptor 0 for device 0x1b1c:0x0c32: Input/Output Error Warn : could not read product string for device 0x2e8a:0x000c: Operation timed out Error: unable to find a matching CMSIS-DAP deviceIt almost feels like these Raspberry Pi devices were developed with only Linux in mind. Wondering if I should use WSL or just switch to a Linux machine. Thoughts? Thanks, Blake

need help setting up raspberry pi as arduino HDMI shield
I'm following this guide ( https://codeandlife.com/2012/12/27/raspberry-pi-as-arduino-hdmi-shield/ ) to setup up a raspberry Pi Zero W as a hdmi shield so that I can display text on the screen and change characters on the screen. I have the arduino setup, I have the Pi zero booted and connectec to the internet. I think i have pyserial installed. I tried to install pygame and it gave me an error.

How to control when RPI camera IR Leds are powered
I've just setup this night vision camera with my RPI
https://thepihut.com/products/raspberry-pi-night-vision-camera
But I have an issue that whenever the raspberry PI is powered, so are the LEDs, this leads to them heating up when the camera is not actually in use (the PI is used for a home hub as well as camera)
While this heat may not matter much, I would feel better if I could control them, and only have them on when I want to use the camera.
Is there any software method for disabling power to the camera until I need to use it? Or any other software method around this?
If no, what would be the simplest hardware method for limiting camera to the power when I'm not using it? (I'm much better at software than hardware)
Thanks!

USB TYPE A onto raspberry pico
I want to add a usb type A onto my Raspberry pi pico W. I thought about just soldering the usb type A connector onto the board and then connecting the correct pins with wires. But im not sure if that is the best way. Also, what are the correct pins XD? I don't have a D+ or D- so is it even possible to do so?
yes I am a newbie 🙂

PI 4 runs 24/7
Hi, do you think it's a problem for the Raspberry PI 4B / (I think 4GB ram) to run 24/7? I run a python script on it that also runs 24/7, (but mainly for timers to wait, so it only really executes an active thing about every 2-3 hours (which takes about 5 minutes) and at night it just waits (again with a timer) for about 8 hours. Theoretically, the PI has to work continuously because the timer/countdown is running. I have no cooling. I have PI 4 case (plastic) and the normal/official PI power supply.

RGB led raspberry pi 4 on base hat
Hello, I'm a student in computer science and we got a project on a raspberry pi. My group and I decided to do a connected lamp so we asked for RGB led and they gave us 2 chainable rgb led v2.0. but from what we looked it work with grovepi but we don't have it. I don't know how to make the RGB led change color or even turn off and the teacher doesn't help us. I tried to use the code of the grovepi but we don't have the di_i2c library which is used everywhere in the code. The other RGB led works on a white board and 4pin so it doesn't help. I'm totally new and don't know what to do, so if there is someone that would be willing to help, I'll be grateful.

Looking for a 64bit display driver for this HAT
Bought this HAT kit for my RPI Zero 2 W ( https://spotpear.com/index/product/detail/id/721/no/666.html ), included documentation only links to a 32bit display driver ( https://spotpear.com/index/study/detail/id/631.html ). I need to run a 64bit OS on this machine, and I was wondering how I would go about finding another compatible display driver for this device.

Can't get the USB-C port to work as OTG
Hi, I am working on a project that needs to use USB C port as OTG. I bought a power hat (X735 v3) to power the RPi4. I am using Raspbian Bullseye. I added “dtoverlay=dwc2” to config.txt, “dwc2” to /etc/modules, and used “sudo modprobe dwc2”. Dmesg says:
[ 3.806204] dwc2 fe980000.usb: supply vusb_d not found, using dummy regulator
[ 3.806633] dwc2 fe980000.usb: supply vusb_a not found, using dummy regulator

[ 4.014966] usb usb3: Manufacturer: Linux 6.1.21-v8+ dwc2_hsotg
however, dmesg-w doesn’t show anything when I try to connect something to the port (phone, USB stick).
What should I do? Could this be a hardware issue?

Pi 4 - Pytorch - Segmentation Fault
Hi there, I built a machine learning model that detects licenses plates. Everything is working fine on my main laptop machine, but as soon as I try runningit on the PI and try passing the tensor into the first convolutional layer I get a "Segmentation Fault" error.
Happy to provide any information that wil help debug this!
