Unable to read output from ML model running on RPi Pico W
I've been trying to use the tensorflow lite micro port for the Raspberry Pi Pico W, to run an ANN that will detect shape of motion of an accelerometer, using the pico-sdk.
I've followed guides and examples on how to setup the TFLMicro model and running it, but when I need to get the model output, it is gibberish and never changes. I've gone into more detail in the issue I opened on the pico-tflmicro repository, which also links to my repository of code I've written till now.
https://github.com/raspberrypi/pico-tflmicro/issues/13
although this is not a generic Pi Pico W specific issue, it can't hurt to ask here.
the pico-specific funtionality is that there is code to interface with the MPU6050 to gather accelerometer data, using the onboard LED using the cyw43 module and interrupt handling on 2 buttons to
1. Record accelerometer data
2. Send recorded data through the model and obtain a classification

project I want to work on I am completely new to pi
I am COMPLETELY new to raspberry, but as I couldn't find one myself, I wanted to make/code my own voice changer using a Pi pico. What do I need to buy, does the pico suffice, what coding language should I try to learn/use? I only really need to have one voice effect for now

Connecting Servo motor to raspberry pi 4b
so i have a Raspberri pi 4b
and i want to connect it to this motor
http://tinyurl.com/3tchkh63
in an other forum i was told that i need a signal matcher so i bought one that translates 3.3v signals for 5v for the motor to register.
but in the end of the day i got these super small female to femal jumpers for the gpio of the pi
how can i connect them safely to the terminals of the above mentioned motor
and secondly how can i wire it up to get the most controllability?

Will I need to solder this converter board?
Hey there.
Quick question about these converter boards:
I am wanting to use this FFC converter board from Amazon for my Raspberry Pi Pico W. Will I need to solder pins onto it so I can use it in the breadboard? Or will it work just fine if I were to plug it with board wires likeso? (right image)

reset password with physical access
What’s the simplest way to reset a password with physical access to a pi? Have one set up but lost the password. I have it set up as a server and want to keep the data. It’s accessible in that I can u plug and remove it and the SD card but it’s not anywhere near a keyboard/mouse and monitor.
I know I can init/sh the commandline.txt but this would then require a monitor and keyboard to change the password.
I have a laptop that I can plug the SD card into.
Whats the easiest way to reset the password?

Git Auth browser
I just installed a fresh SD card for my pi zero w with ras os lite bullseye and have been setting up an i3 environment from scratch. However I think there's been an issue with setting up netsurf as my default browser, so that I can Auth my github account. When I try to run gh Auth login it opens my file manager (spacefm) instead of my browser. I've ran the update-alternatives - - install x-www-browser /usr/bin/netsurf and it appears when I try the config flag.
Would be great to have access to my private github repost (´ω` )

Cannot Ping RPi 3B From Windows Laptop
Hello! I am trying to use my RPi 3B to run my 3D printer with Klipper/Mainsail. I've installed Klipper on the printer, Mainsail on the Pi, and am trying to access the Pi over my network. One of the things I need to do is find the USB port that the printer is using on the Pi, and to do so I need to connect to the Pi using PuTTY, but PuTTY is never able to connect. When I try pinging the Pi's IP address, 192.168.1.32 (found using Zenmap), nothing comes back.
Why is this happening? Why can Zenmap see the Pi on my network but I can't ping it using the command prompt on my laptop? Sorry if I'm leaving required info out, I'm very new to this.

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?

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)

Remote Headless Install while currently booted.
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 😛

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
