I'm not familiar with the 3200? That's not 3002slackjack wrote:Yes it is the MCP3200.
That's sounds like a simple,practical solutionGert van Loo wrote:I solution which I suggested in the past and which seems to work for slow changing signals,
is to add a capacitor to the input.

GND AD0 3.3V
Now I have found something else I did not expect, but which may help someone to put me straight.
I have run the dad.py program and it does not do what I expect either, but does do what is shown in another tutorial (http://www.tech-fruits.com/all-tutorial ... onverters/).
The output from a digital input of 255 is analog 634. I expected the 255 to corespond to 3.3 V and therefore to return analogue 1023.
Please tell me what I am missing here.
