Hello iam having trouble coming up with how to go about measuring a differential voltage from a rs-485 transceiver using a mcu.What iam trying to accomplish is getting a "oscilloscope type" graphical view so they can see the signal,obviously the resolution and accuracy wont be great.I was reading around and thinking i can use a non-inverting op-amp for the negative signal then have two adc(+,-) pins with voltage dividers to step it down to Vcc?Iam completely lost and still new to this so any input is appreciated.Thanks
