Stable ADC readings

[dream-]

Hi,

What about reinitialise your Wsum value to 0 @ each 50 samples batch ??? don't you run this loop in another continuous loop ... ???

Oh I do. I left that part out of the code I pasted, but it is indeed running in an outside continuous loop.

PinProbe VAR PORTA.2
...
myLoop:

WSum = 0
Pause 100

For i = 0 to 49
ADCIn PinProbe, W0
Pause 10
WSum = WSum + W0
Next i

W0 = WSum / 50
...
LCDout $fe, 1 'Clear Screen
Lcdout $fe, $80
Lcdout "Reading: ", DEC W0

Goto myLoop

The readings I get with the ADCIN method are in the ballpark but move around too much. With the "manual" ADC method I get a stable value.
