If its battery voltage then you need to ensure that the input pin voltage will be valid over the range of possible battery voltages. Also if you're not feeding into a schottky input then you will need to meet the minimum rise time requirement.

He has a digital 12V or 0V signal which needs to be captured, so he only cares about safely detecting a 1 or 0 state.

Please note all diodes needs to be soldered different. I used the frankeso symbol that has wrong pinout :-(

I am updating the module with the right symbols now.

This is just another example of what issues the hated rusefi lib does.

I even used a micro usb symbol with d+ and d- switched.
It's at the uart on the boards you got from me.
It took me a long time to figure out..

So please follow my advice to make steps to get rid of it, instead of letting it grow.

For this, you need to put the diodes upside down, and turned

I found L9966 for analog inputs of my custom ECU.
But I cant find any datasheet!
