Pico W connected to wifi but not the internet
hey, i have a pico w and i had it working with wifi a few weeks ago. but today the same script keeps getting EHOSTUNREACH whenever I try to connect to something outside of my network. I have confirmed that the wifi connects, I have an IP, the default gw is set, I can ping the default gw, but when i ping something like 8.8.8.8 or 1.1.1.1 or if i try to socket.connect() to something like google.com I just get EHOSTUNRECH. I've rebooted a few times. Can anyone think of what might be causing this problem? using micropython.

What's the best way to read analogue input using GPIO?
I'm reading the Sparkfun sound sensor amplitude/envelope which is analogue. The sensor doesn't seem to have I2C sadly. I think I could use SPI instead, but is there an easier way to read this data that I'm missing? Also, do you NEED a MCP3008 to read the data?
Link to the sensor: https://learn.sparkfun.com/tutorials/sound-detector-hookup-guide#software-example

M.2 NVME Drive doesn't list in the system on my Raspberry Pi 5 with Pineberry Pi Hat.
I need help with configuring my m.2 nvme. I have watched several guides/tutorials which explain how to setup the nvme to show up and eventually boot from it, but unfortunately mine just doesn't show up, for example lsblk will just show my current usb to sata 3 drive. Currently I booted from normal sata 3 ssd with usb and I have fully updated the system also inputed dtparam=nvme and dtparam=pciex1_gen=2 in bottom of the /boot/firmware/config.txt. I have also tried to change the option to gen 3 since my ssd and hatdrive fully support pcie gen 3. (btw the power light on the hat is on, also the connection and everything between the raspberry pi and the hat is connected properly, so it's most likely software issue?)

Micropython modules conflicting with existing modules on visual studio code
So i've got a project that I created using micropico
json
{
"python.linting.enabled": true,
"python.languageServer": "Pylance",
"python.analysis.typeCheckingMode": "basic",
"python.analysis.diagnosticSeverityOverrides": {
"reportMissingModuleSource": "none"
},
"micropico.syncFolder": "",
"micropico.openOnStart": true,
"python.analysis.typeshedPaths": [
".vscode\\Pico-W-Stub"
],
"python.analysis.extraPaths": [
".vscode\\Pico-W-Stub"
]
}
this is the settings.json. My issue is that doing import os, the intellisense will think im using the usual python os module, not the one declared in the Pico-W-Stub folder. Is there any way to override this?

SIM800L and rp2040-zero echoes commands back
I have a sim800l connected via uart to the pi and wrote a sample micropython code to test it, but the weird thing is that it just replies with the same command instead of executing it, in the documentation of it ive read something about echo mode, could that be an issue?
https://cdn-shop.adafruit.com/datasheets/sim800_series_at_command_manual_v1.01.pdf
even if i just send pizza' to it it replies with b'pizza', same thing with the AT commands (see code below), any ideas what im doing wrong?
py
from machine import UART, Pin
import time
uart = UART(1, baudrate=9600, tx=Pin(4), rx=Pin(5))
uart.write('pizza')
time.sleep(0.1)
response = uart.read()
print(response)

Nevermind, I read a bit on how it could be doable, but that's going to take wayyyy more time than actually go and grab the pi for a reinstall haha š

VirtualGL is using LLVMPipe and not the GPU
What I currently have
- Raspberry Pi 5 with 3a/5v charger and fan
What's my purpose here
I want to use RPi's GPU to its full core
I'm currently using Xpra and hosted it online so that my friends can view and do stuff along with me
However glxinfo reports LLVMPipe is used so I believe it's cpu's complete work?
I've compiled VirtualGL and ran but then found that it also uses LLVMPipe [note the attachment pic]
What have I tried for alternatives
I've used TightVNC with noVNC for achieving similar to Xpra but then sound wasn't there [the forks with sound seems impossible for me to config]
I noted that RealVNC uses Broadcom's GPU in Service Mode which gave me some hope but then it wasn't working with noVNC, the authorization protocol resulted in some error [ https://github.com/novnc/noVNC/issues/1826 ]
i'm newbie so idk much, just read the docs and tried stuff then failed miserably :C

Reprogramming Pico live, 2nd CPU doesn't reset
I've discovered that if I reprogram the Pico firmware live through a pico probe and tell it to reset, only processor 0 gets reset. Processor 1 seems to be stuck doing something else or crashes, and I have to fully power cycle it. Is there something I can add to "program build/pico_motor.elf verify reset exit" to reset core 1?
I tried using the function multicore_reset_core1() upon entering main() on core 0, but that didn't help.
I also tried changing the openocd command to something I found on a forum, but that didn't help either: openocd -f interface/cmsis-dap.cfg -f target/rp2040.cfg -c "program $ELF verify reset ; init ; reset halt ; rp2040.core1 arp_reset assert 0 ; rp2040.core0 arp_reset assert 0 ; exit"

help me find what connection in pico killed my usb hub
Hi all,
need some help with pi pico.
I followed a tutorial to get a 4 digit 7 segment display work with pico, and it worked absolutely fine, I was able to see the display working properly. (https://how2electronics.com/using-7-segment-display-tm1637-with-raspberry-pi-pico/)
But then I wanted to find how much current was consumed by the display, so I did two experiments (in both cases pico is connected to macbook pro via usb hub):
1) I connected the display to the pico and measured the current by connecting the multimeter in series with the pico(pin 38) and the ground pin of the display. (I did not remember exactly, but the display did not turn on I guess)
2) Did the same experiment as above, but this time I connected the multimeter in series with the pico(pin 36) and the vcc pin of the display,
when I did this, the usb hub that I had connected to use the pico with macbook just stopped working forever. but the pico itself just works fine.
I felt very bad for what I did, lost my usb hub.
But still unable to understand what went wrong, pls explain to me what happened and how to avoid it in the future.
Attaching pictures of my second experiment.

Building audio player
Im a programmer and i wanted to build an cli app to play music from the internet, would be cool if i could run it on dedicated device. So im thinking maybe i could build a DAC with raspberry Pi? Since it can run Linux so i think wouldnt be too hard. But i have no knowledge beside the programming part so, any resources for building HI-FI DAC with raspberry Pi? Maybe some extra device that i need? Some documentation? Any help would be appreciated, thanks!

Trying to control a 3.5" RPi Display with a Pico, confusing controls
Hello, I have recently started work on trying to display something to my pico with a Raspberry Pi 3b RPi screen, but the pins are extremely confusing. I found the documentation for the chip that the display uses (ILI9486) but the pins on the actual display do not match up with the inputs of the display (attached image). I'm not sure exactly what to do, and how to communicate with the screen.

Large self-playing pinball machine
Hello, I'm working on a pinball machine project in which the pinball is a small-sized soccer ball. My friends decided they wanted more points for risk (this is for a "competition"), and they decided a self-playing pinball machine would be cool.
this is what we want to achieve but scaled up and less expensive (Wood isn't a problem) :https://www.instructables.com/Pinball-Machine-With-Raspberry-pi/
I have access to 2 Raspberry Pi 3s, 1 Raspberry Pi 4, wood tools/saws, and other sensors and electronics.
I would appreciate any suggestions with the coding or with the wires. I don't have any progress so far with the code or wiring except for making the frame of the pinball machine. I have also worked on an Arduino controller.

Vulkan drivers installation fails
Urgent???
This isnāt the typical I need help topic. If I canāt fix this I canāt use my raspberry pi. Iām not willing to reflash my micro se card a million times until it decides it want to work with me. So I was using PiKiss to install Vulkan Drivers on the Raspberry Pi 5. One small issue the two times I had to reflash my sd card and redo the process, it stopped the first time a random amount of time during either downloading or installing the drivers. The second time is when it would work, the issue is, the second time I rebooted then tried to install then it installed without issues, or so it seemed. I downloaded some Vulkan demos to test and they worked flawlessly. Cool right? WRONG 1. Some open/webgl websites that I tried had HORRIBLE fps. Just as a test I pulled screenshots from a prior flash of the sd card without all this Vulkan nonsense. 60fps on the website! After both of these 2nd Vulkan download attempts I would average 15-23fps. Somethingās wrong!! I reboot and low and behold NO MORE GUI! šš¤¬š¤¬ Now Iām just mad. I knew the GUI was gone because I waited 15 minutes for it but the text cursor you usually see for a split second on boot was it here flashing. So I hold alt+F2 so I can use text mode. And when I tried to run the Vulkan program that ran not even 5 minutes ago shows the following image. Please help Iāve been troubleshooting for hours and now Iām actually getting to that point where tears are about to start rolling because Iāve wasted my entire day on this with no success!
TLDR: how do I get VULKAN drivers installed with zero error?

Raspberry Pi 4 connected to my rental apartment's router, am I in danger?
So basically I just moved in with my gf and I found a raspberry pi4 on our apartments router. The landlord says it's for wifi expansion and smart home devices, but I am hesitant to believe that's all it does. Is there a way to test if I or my data is in danger? And if so, would it be hard for me, as I did very little to none python programming in my life?
It's a raspberry pi4 with raspbee 2 on it, it's connected directly to our router, but also to the wifi.
