New Wheel

Hi, Im a programmer by trade, but a total newbie to Python, especially for EV3.

I need to add a new wheel. It’s the Motorcycle wheel (part: 88517c02) (100.6 D, 17 W). I created the class in the wheel.py file. VSCode recognizes it, but when trying to run the code on the EV3, I get the following: File “/home/robot/vscode-hello-python-master/hello.py”, line 8, in <module> from ev3dev2.wheel import MCTire ImportError: cannot import name ‘MCTire’

What am I missing?

• **ev3dev version:4.14.96-ev3dev-2.3.2-ev3
• **ev3dev-lang-python version:

I am not familiar with the workflow for using VSCode to edit and deploy changes to ev3dev-lang-python but I can walk you through how to get this up and running (just not using VSCode).

• ssh to your ev3
• $ git clone https://github.com/ev3dev/ev3dev-lang-python.git
• $ cd ev3dev-lang-python
• $ export PYTHONPATH=/home/robot/ev3dev-lang-python/
• use an editor like nano or vim to edit ./ev3dev2/wheel.py to add your new wheel class
• copy your hello.py program to your EV3
• $ python3 hello.py

@dlech – Thank you!!! I’ve successfully connected my EV3 via usb to my mac and shared out the internet to it.

The issue now is when I download/run hello.py from VSCode, it fails… but when I run the code via SSH (or directly from EV3, it works. Its a cludgy workflow, but I’ll work with this for now.
