PBP2.50b and POT command problem ?

[RFsolution]

Hi

I'm trying to use the pot command in order to read 8 switches
I have put 8 different resistors in serie with a pushbutton
and as described in the pbp manual 100nf to ground

Then to test I took a 47K pot with 100nf and the following code
but regardless off the value (128) i can see the var changing to 128 max and then it goes back to 0 even if I still continue increasing or decreasing the resistance value

tried 220nf and 10nf the change the time constant with no result

anyone who can reach a full 0-255 range with 47K pot and 100NF ?

loop:

pot portc.7,128,b0
pause 50
Lcdout $fe, 1 ' Clear screen
Lcdout #b0
goto loop

And you've tried changing SCALE in the POT command? Or used the example code in the book to find the optimal SCALE value?

Put a PAUSE 1000 before goto. Increase PAUSE 50 to PAUSE 200
