Could not determine default I2C bus for platform

Nick-Harvey commented 2 years ago

Hi there,

I got the Picar Pro and I'm trying to get the webServer running and I get the following error:

Traceback (most recent call last):

A quick google search says that this is using a deprecated Adafruit_Python_GPIO library and this error keeps you from getting past the first few steps of the build.

Hello, It may be a problem with the version of the Raspberry Pi image file. Please try the following two methods:

Download Raspberry Pi OS (Legacy): https://www.raspberrypi.com/software/operating-systems/ Raspberry Pi official description of the Raspberry Pi OS (Legacy): https://www.raspberrypi.com/news/new-old-functionality-with-raspberry-pi-os-legacy/
Download the previous Raspberry Pi version, Raspberry Pi image file (2021-5-07) download address: https://downloads.raspberrypi.org/raspios_armhf/images/raspios_armhf-2021-05-28/

Best!

I have the same problem. Picar pro bought in September 22, with a RPI 4b.

Installed the official RPI OS tried the legacy and non legacy and didn't solve the problem

Did you manage to fix it? If so how?

SOLVED: by using the 2021 os image. But now new issue, webserver not runing automatically in background

adeept commented 1 year ago

Hello, This is due to the incompatibility between the Raspberry Pi image file and some dependent libraries. Please download and burn the Raspberry Pi OS (Legacy) according to the content "Method one" in the link below, then configure SSH and WiFi, and run the setup.py program after downloading the product code.
