Hello!

I just want to make sure I understand correctly…  
If I want to install legacy pyuavcan I use  
`pip install uavcan`  
Otherwise I use  
`pip install pyuavcan`  
for v1

?

That’s right, yes. We are going to change it though:

I noticed that python can was added to legacy driver a while ago. Are the installation options (transport\_) explained in  
[https://pyuavcan.readthedocs.io/en/stable/pages/installation.html](https://pyuavcan.readthedocs.io/en/stable/pages/installation.html) available for legacy uavcan as well?

No. There is only one configuration available for the legacy library, which is the default one.
