Re: Non Powered Devices

Found some issues on the Internet about this subject. Saw also some=20
discussion about a difference between technology and the registered=20
name. E.g. some chip manufacturer integrated the I2C bus (original IP of =

Philips), but called it 2-wire bus. The patent has been expired, but the =

name is still registered. Maybe that is the reason why companies like=20
Espressif and Allwinner don't talk about their CAN implementations.
