Why now of signal transmission bus, iic, spi, can, 485... ) are voltage signal? I think the current signal is more stable. Do you have any current signal of the bus?

CodePudding user response:

Have, like an LVDS signal is the current signal

CodePudding user response:

This problem is very difficult

CodePudding user response:

This just form the difference, resistance fixed voltage is not response current

CodePudding user response:

High speed usb is not?
