Matt,
I set mine up for analog on pin 1.
I used a pot off the 3.3 v supply
Here is the results.

There is quite a bit of variation in the hundreds of volts.
 (.01) I need to look at the 3.3 volt supply with my scope to see
if there is any noise on it.

It also takes about 6 msec for the A to D and the print on the screen.

I'll remove some of the characters sent to the screen and see if that helps.
I suppose saving the data on the SD card would take longer than writing
to the screen. We shall see.

Mode 1


SetPin 1, 1 'set pin 1 to analog in
Timer = 0
For x = 1 To 35
data1=Pin(1)
Print data1;
Print "   ";
Print "  Number of msec =";
Print Timer
Next x
