What's your current formula?
A third degree polynomial didn't fit?

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.

f(x) = 5167.68(0.98^x)

could be more simple than you think

Nope, bad link...

well, I changed it up and am using three diff power curves to keep everything within 1 degree +/-
only thing that is trouble is negative exponents.. tryin to figure out how to simplify it out so pbp can do it, but im am sucking on figuring this out. lol

You could still build a lookup table and use some interpolation between some points, that should do the trick and way easy to implement.

Hi, Folks

Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

IF there is the word "Problem" in your question ...
certainly the answer is " RTFM " or " RTFDataSheet " !!!

Wow, you mention that and I look at the gauge that the sender was supposed to work with and they did that!

So I looked at the resistor that was used, its 510
It brings the change in resistance per degree down to
3 ohm from 100-150
2 ohm from 151-200
1 ohm from 201-250
Isnt that crazy.
