So I downloaded the emulator and ROMs but when I open the game the game crashes than I open the game once again and the emulator crashes any fix?btw I’m on iPhone 12 iOS 17

Hello,

I want to use Ubuntu Desktop or Server (doesn't really matter which one) on my Raspberry Pi 5 using my NVME 1TB SSD. I have no SD-Card so the way im installing Ubuntu on my RPI is that I plug the USB Stick into my normal Windows PC, then using RPI Imager flash Raspbian (Raspberry PI OS) onto the USB Stick, then plug the stick into RPI and boot up, on the RPI OS go to /boot/firmware/config.txt then add dtparam stuff to enable pci, next open Imager and install Ubuntu os on the ssd. Then just unplug the usb and reboot, done.

But now I want to add full disk encryption to to that Ubuntu system on the ssd, how can I achieve this?

Hello there, I recently bought a RasPI 3.5-inch TTF touch module and am facing issues using it. The module, even after all drivers are installed, does not display any output. The guild on the website also does not go into detail on how to troubleshoot it and I was not able to find any useful info on debugging this issue.

I will list out everything I have done until now: - Reinstalled Raspbian Desktop image. - Configured the Xserver to work (even though the driver install script does it). - Tried to manually display an Image (this is interesting and I will further explain this below). - Used Python to try and display an image.

So at first, I thought while installing it, I followed the standard procedure and it did not display anything other than a black screen with an _ in it. next, I tried to delete everything and then reinstalled it, but still no luck. Next, I removed the image and used a fresh image, no use. then I tried using this command: ``` sudo fbi -T 1 -d /dev/fb1 -noverbose -a /home/pi/test_image.png

``` to forcefully display something and when I did this a terminal interface got printed but was not usable, then I figured the framerate was flicked so, I tried changing the refresh rate that also did not work.

Now I am lost on what to do. Any suggestions will be appreciated.

I am using a rasp pi zero 2 w for this.

Hi,

for a project I bought a 2.8inch DPI LCD and WM8960 Audio HAT both from Waveshare. Since the audio hat has GPIO extension I thought it would it be possible to stack one on top of the other. THe idea is to give "comact" audio and video output to a Raspberry Pi Zero, as much pankake as possible with no wires going around. For speaker I'm using 2w 28 mm speakers, no need for hd audio.

Well, I followed the intsructuon to edit the config.txt and add the overlays for the LCD and all went ok, once I understood that the drivers works only with Legacy 32 full image. Then I installed the audio drivers and the display stopped working. I uninstalled the audio drivers and checked the config.txt file were clean and the display worked again.

Is there a way to make this happen? Can you suggest another compact way of bringing audio out for the rpi? Maybe by using a usb board, taking data and power from the testing pads?

Hi everyone,

I’m working on my first Raspberry Pi project and could use some guidance. I’m building a theremin-like digital instrument using two SHARP GP2Y0A51SK0F IR sensors. Each sensor is supposed to trigger one of five audio clips based on distance.

Here’s what I’ve done so far:

• I’ve set distance thresholds for each audio clip (e.g., 14-15cm triggers Clip 1, 11-13cm triggers Clip 2, etc.).
• I’ve written code to handle sensor input and play the clips accordingly.

However, I’m encountering a few issues:

• Erratic Playback: The audio clips play erratically and seem to be cut off at the low and high ends of the distance range.
• Persistent Playback: When no object is in front of the sensors, one clip plays continuously until something comes into range.

I’m wondering if:

• There might be improvements or adjustments I can make in the code to address these issues.
• The IR sensors might not be ideal for this application, and if alternatives like ultrasonic or Time-of-Flight sensors could be better (ideally want to solve with coding before buying new hardware)

Here’s my code for reference:

Hello all! I'm new to the Raspberry Pi scene; however, I have recently found my interest piqued by the tinkering possibilities of the Raspberry Pi. I am currently in the process of creating a NAS server that will be primarily used to maintain a photo library to offload from my phones. I am looking for suggestions, feedback, and any remarks on my build. The build will be as follows: - Raspberry Pi 5 - Argon Neo case with NVME support - 64GB Micro SD to download Pi OS Lite and Open Media Vault - 1 TB Crucial NVME

Additionally, I am also planning on buying a Black Shark phone cooler that I will stick above the Argon Neo's aluminum case with the theory that it will cool the metal down, which will cool the air within the case down, and therefore the fan's in the case will be circulating cold air to the Raspberry Pi.

I understand some of you might be asking me why I am not running RAID and multiple bays. Well, I don't want to increase the budget of this build anymore. It was supposed to be USD 250, and I'm already at USD 260.

Hi, Recently I bought a Raspberry Pi 5 so that I can use it in a project of mine, an autonomous car.

Unfortunately I'm not very experienced with electronics and I need help because I see that everybody online chooses different parts.

I want the car to be powered by a single LiPo battery with 11.1V and 2200mAh (with the XT60 plug). I want it to power the Raspberry Pi 5, a small 130 motor (3V) and a servomotor.

My question is, how do I power all of them from the same battery? I've searched and found that I can use a motor driver, I've seen more complex builds that use some additional parts. I'm just really unsure on how to connect all these so that they are powered by the Raspberry Pi only. I doubt the motor driver can power all 3 of them so I'm searching for either something else or something additional.

If anyone has some recommendations, articles that I can read, videos or anything to point me in the right direction, please send 'em my way.

Heyo everyone,

So this is quite frustrating..

I got myself a raspberry pi 5... A rasperry pi 5 pcie M.2 hat ( The pimoroni Duo )

The idea is to use proxmox on the PI. Just for fun.

My current problem is that the ubuntu server can't see nor mount the nvme.. And whenever I search for help I get loooots of sites helping me on how to boot from an nvme.. I do not want to boot from my nvmes.. I want the os to run from the SD card and then mount the nvmes into the os...

Does anyone here have any ideas how to accomplish that?

Thanks for reading.

P.S. I'm slightly triggered that there's no one just mounting an nvme.

I am using a very basic test code provided at the end of this video linked below (I'm basically trying to rebuild her robot with a few extra mods but I haven't even added the mods yet)

https://www.youtube.com/watch?v=Bp9r9TGpWOk

I keep getting this error:

RuntimeError: The GPIO channel has not been set up as an OUTPUT

It marks the error at the first line of my forward function.

I have tried googling the solution and this is the only link that comes close to solving my issue but not quite as I'm not using GPIO.cleanup(), so I have no idea what else my issue can be. I've reviewed the code a dozen times, and it should be working, as I'm essentially doing this but with some extra steps:

import time

import RPi.GPIO as GPIO

GPIO.setwarnings(False)

GPIO.setmode(GPIO.BOARD)

GPIO.setup[29, GPIO.OUT]

GPIO.setup[31, GPIO.OUT]

#30 GND

GPIO.setup[32, GPIO.OUT]

GPIO.setup[33, GPIO.OUT]

GPIO.output(29, True)

time.sleep(3)

GPIO.output(29, False)

GPIO.output(31, True)

time.sleep(3)

GPIO.output(31, False)

GPIO.output(32, True)

time.sleep(3)

GPIO.output(32, False)

GPIO.output(33, True)

time.sleep(3)

GPIO.output(33, False)

time.sleep(3)

exit()

And this code worked perfectly fine. I don't know why it shit the bed as soon as I brought classes into the equation. The pins all work, and they all respond to the pi calling them out exactly like this. I think it must be something in my syntax that's making it freak out and throw this error. I removed all the extraneous stuff I added in for my future mods (except for some of the imports), and nothing fixed it. I'm putting my code below.

#GPIO Settings

GPIO.setwarnings(False)

GPIO.setmode(GPIO.BOARD)

#labeling pins

GPIO.setup[29, GPIO.OUT]

GPIO.setup[31, GPIO.OUT]

#30 GND

GPIO.setup[32, GPIO.OUT]

GPIO.setup[33, GPIO.OUT]

class Robot:

def __init__(self, name, rwheel, lwheel):

self.name = name

self.rwheel = tuple(rwheel)

self.lwheel = tuple(lwheel)

self.rwheel_f = int(rwheel[0])

self.rwheel_b = int(rwheel[1])

self.lwheel_f = int(lwheel[0])

self.lwheel_b = int(lwheel[1])

def forward(self, sec):

GPIO.output(self.rwheel_f, True)

GPIO.output(self.lwheel_f, True)

#stop

time.sleep(sec)

GPIO.output(self.rwheel_f, False)

GPIO.output(self.lwheel_f, False)

def backward(self, sec):

GPIO.output(self.rwheel_b, True)

GPIO.output(self.lwheel_b, True)

#stop

time.sleep(sec)

GPIO.output(self.rwheel_b, False)

GPIO.output(self.lwheel_b, False)

def lturn(self, sec):

GPIO.output(self.rwheel_f, True)

#stop

time.sleep(sec)

GPIO.output(self.rwheel_f, False)

def rturn(self, sec):

GPIO.output(self.lwheel_f, True)

#stop

time.sleep(sec)

GPIO.output(self.lwheel_f, False)

#establishing ob

smelly = Robot("smelly", (29, 31), (32,33))

#test run

smelly.forward(3)

smelly.backward(3)

smelly.lturn(3)

smelly.rturn(3)

Again, I'm following her code exactly, so I'm not sure where I could have gone wrong on this. Again, I get the error attached to the first line of my forward function.
