Adding a Power Button
Previously I had set up a power button by having one pin connected to gpio 3 and another to GND and I had a script that ran in the background. I tried the same guide as previously and watched many more yet none seem to work.

Running Script on startup
Previously i used "sudo nano crontab -e" and pasted the command at the bottom, and this worked however now when i try do that on my new raspberry pi (same model) it does not work? is there another way i can do this?

why does raspberrypi 400 use the swap partition when ram isnt full
My raspberry pi has 4GB ram and usually when the available ram is down to about 1GB my raspberry pi just decided to not use the ~1GB avliable ram and start using the swap partition causing my system load to sky rocket to over 100 (due to high loads of IO)
Any idea on how to fix this issue?

Using ATWINC1500 with Raspberry Pi
Hey everyone, I made a small HAT for the raspberry pi. It has an ATWINC1500 WiFi module. Any idea as to how to make it show up in ifconfig as a normal wifi interface? I've tried the WiFi101 libraries but ofc since they're intended for arduino, there's no makefile

Stream Picamera module 3 over network
Hi,
I am building a video surveillance system. I have a Raspberry PI 4 to which a Camera Module 3 Wide is connected.
My goal is to recover the image from this camera on another Raspberry (PI5). I currently have a Python program that allows me to stream in MJPEG but the quality is not optimal. I would like to stream in RTSP but I haven't found a working method.
Have any of you ever done this?
Thank you in advance for your answers.

RPi 5 on 4k HDMI TV
Raspberry Pi 5
Ubuntu 24.04 LTS
LG 55uq7070zue TV (4K, 60Hz)
The HDMI cord and adapter definitely work, but I can't get it to display on the TV. The TV gets input, but only displays a black screen.
How can I get my Pi 5 to display on this TV?

Need help with an I2C LCD display
I have a breadboard with Raspberry Pi Pico on it and connected an I2C LCD Display. I can't get the LCD to "work" though. Can't print anything on it despite having the libraries installed on the micro controller. I've tried .putstr and .putchar but neither work, although .backlight_on and .backlight_off work. If this makes things clearer, I have a 2x16 LCD with I2C LCM1602 converter

Updating pi pico directly or remotely
I’m just getting started with the pico. With the pi I’m used to uodsting it remotely so it doesn’t have to always be plugged into my computer.
I just assumed the pico would be the same but after about a day of messing about trying to get WebREPL set up, telnet, ftp), all of which has just sent me round and round in circles) I wondered if I’m just approaching this wrong.
Is the idea with the pico that you just have to take it out of whatever device it’s sitting in and update the code manually when you want to change it? I am a bit confused about this as it seems to be what most people do but that seems quite difficult to do if you want it embedded in something and don’t want to be endlessly unscrewing and taking everything apart.
On the other hand maybe the idea is that these devices are supposed to be for one very simple bit of code and shouldn’t need changing a lot?
I feel I’m missing something very simple here.

Help Needed: Interfacing ST7302 LCD Display with Raspberry Pi Zero 2 W
Hello everyone,
I'm currently working on a project where I need to interface an ST7302 LCD display with my Raspberry Pi Zero 2 W, and I'm running into some issues. I’ve tried following various guides and repositories, but haven’t been successful in getting the display to work properly.
Project Setup:
Display Model: ST7302 LCD
Microcontroller: Raspberry Pi Zero 2 W
Connection Type: SPI
Connections:
> GND - GND
> VCC - 3.3V
> SCL (SPI Clock) - GPIO 11 (SPI0 SCLK)
> SDA (SPI Data In) - GPIO 10 (SPI0 MOSI)
> RES (Reset) - GPIO 25
> DC (Data/Command) - GPIO 24
> CS (Chip Select) - GPIO 8 (SPI0 CE0)
Problems Encountered:
Initialisation Issues: The display does not seem to initialise properly. I suspect the initialisation sequence might be incorrect.
Noise on Display: When running the code, the display shows noise for a few seconds and then goes blank.
No Clear Output: Attempts to display patterns or text have been unsuccessful, resulting in either no output or random pixels.
import spidev
import RPi.GPIO as GPIO
import time
GPIO.setwarnings(False)
DC_PIN = 24
RESET_PIN = 25
CS_PIN = 8
spi = spidev.SpiDev()
spi.open(0, 0)
spi.max_speed_hz = 500000
spi.mode = 0b00
GPIO.setmode(GPIO.BCM)
GPIO.setup(DC_PIN, GPIO.OUT)
GPIO.setup(RESET_PIN, GPIO.OUT)
GPIO.setup(CS_PIN, GPIO.OUT)

write_data(0x00)
clear_display()
try:
while True:
time.sleep(1)
except KeyboardInterrupt:
GPIO.cleanup()
spi.close()
What I've Tried:
Double-checked all connections.
Verified GPIO pin numbers and corresponding functions.
Attempted different SPI settings and initialisation sequences.
Questions:*
Is there anything obviously wrong with my code or connections?
Can anyone provide a correct initialization sequence for the ST7302 display?
Are there specific SPI settings that I should use for this display?
Any help or suggestions would be greatly appreciated. Thank you!

Hi, I'm trying to install raspbian on a ssd m2 I just received. I don't have an adapter so I mounted the ssd on my laptop to use rpi imager. The problem is that the imager does not see the ssd when it's time to install the OS. I've tried to format the ssd but still doesnt popup in the list...

Raspberry Pi 5, Pimoroni NVMe Base
I just got the NVMe base for the Raspberry Pi 5 (Pimoroni PIM699), and I must say the circuit board quality is impressive! Promising start. 🙂
To my project:
I slotted a Micron 256GB NVMe (Gen3, 4x) into the base board, attached the base board to the RPi5, and the Pi recognizes it. I used Raspberry Pi OS 64-bit and then used the imager to install Raspberry Pi OS 64-bit on my disk.
However, when I try to boot from it, I get a message that it fails to boot from NVMe, with options to hold shift for network boot or press escape.
The NVMe I'm using is an MTFDHBA256TCK-1AS1AABHA from Micron Technology Inc.
https://www.digikey.no/en/products/detail/micron-technology-inc/MTFDHBA256TCK-1AS1AABHA/10320942
Has anyone encountered similar issues or have any advice?
Edit: I see now that the disk is not on the list of supported disks on the Pimoroni website. Is it still possible to make this work?

Pi5 + Moonlight/Sunshine - No Audio coming through HDMI & case fan not working/always on.
Hi, I'm new to this so please explain to me like I'm five! Thanks.
Edit: Audio topic was finally solved. 3rd party software was interfering with the routing of the sound to sunshine (Steelseries GG Sonar)
my case fan (white one) is either always if using gpio as seen on the picture, or not at all, if connected on Gpio 17. (tried to do this: https://howchoo.com/pi/control-raspberry-pi-fan-temperature-python/)
can you tell me what information you need from the terminal in very simple language because I really, have no idea what i am doing. Thank you so much!
