Pulsin circuit ? Can't find it..

Steel

So somewhere, Parallax has a circuit for reading a variable resistor using pulsin.· I can't seem to find it anywhere...

I know that it is a variable resistor with a capacitor connected to a BS2/SX pin.· The pin is set up as an output, held high, set as an input, and then a counter counts how long the pin stays high (or time for the capacitor to discharge.

I just cant remember how to connect the wiper of the resistor, so I am trying to find that circuit schematic.

Can anybody help me?

You generally use RCTIME for this sort of reading. You can use PULSIN but it gets set up (code-wise) a little differently.

There are circuit and resistor/capacitor combination suggestions if you look up the RCTIME command in the Pbasic Manual.

That's the one.

Thank you.· I found it real quick.
