For Picar-x Raspberry PI 5
I assembled the car ok, but, there are a few issues.
When I image a new storage card with the latest Picobricks code, the card will not boot.
When I try the Sunfounder app, it will not connect. I have verified that both are on the same network and I can even connect via SSH on my phone. When I add the code and run the example, I get the following errors:
~/picar-x/example $ sudo python3 13.app_control.py

picamera2 0.3.22

^^^^^^^^^^^^^
OSError: [Errno 6] No such device or address
I don’t know the product nor anything about the code that comes along with it but I noticed a potential typo in your code.
Not sure if this was a copy/paste error or not but ….
self.config_flie shouldn’t that be file instead?
omg! never saw that!. And,when I go to edit the file, it has a lot of references that use flie. Will take a while to fix.
This is a big fail on Sunfounder. And I have to wonder, what else is wrong. They need to first fix their documents.
What system are you currently using, and what version is it?
Did you encounter any errors while installing all the library code? If so, please provide a screenshot of the error to help us analyze and resolve the issue.
All modules installed just fine, no errors encountered
Here is my system; output of uname -a Linux darylpi 6.6.51+rpt-rpi-2712 #1 SMP PREEMPT Debian 1:6.6.51-1+rpt2 (2024-10-01) aarch64 GNU/Linux
Also note, some of the examples work just fine, like moving etc. However, the camera isn’t working;

This camera test code worked and produced an image within VNC;
from picamera2 import Picamera2, Preview
import time
picam2 = Picamera2()
camera_config = picam2.create_preview_configuration()
picam2.configure(camera_config)
picam2.start_preview(Preview.QTGL)
picam2.start()
time.sleep(2)
picam2.capture_file(“test.jpg”)
So, with the fixes to the typos in picarx.py the camera is now working.
However, the Sunfounder App for Android (Galaxy s23) won’t connect. Both are on the same LAN and I can connect to the Raspberry PI via an SSH app on the phone.
Not sure how, but, I can successfully connect to the app.
However, there is no ‘Picar-x’ applet. So, I don’t know what widgets to add and their values.
I did try the other car applet, but, got this error;

After successfully connecting to the app, click on “Create Remote.” In the presets section, you can swipe to the right to see the PiCar-X preset templates. Just click on “Use” to proceed.
