Hi guys,
I use a megasquirt ECU permanantly hooked up to a linux system with touchscreen. I'm in the process of binning the dials completely and using just the screen.
I'm slightly stuck at the fuel gauge stage.
The ECU has a spare input which accepts 0-5v. It also has a 5v reference output easily available.
The fuel level sender is a potentiometer (with just 2 connections) of just a little over 0 - 118 ohms (tested on my meter)
What im after is how do i use what i have to create a nice 0-5v output from this.
Many thanks in advance, and if i suss it out i'll post back with how... I guess it will be simple, but i've only ever followed circuit diagrams before, never had to figure these things myself.
