Check out this link:и http://www.phanderson.com/stamp/intro/intro.html and also www.google.com (http://www.google.com) (type in "BASIC Stamp and ADC0832") and you should find the information that you are looking for.

Check out this link:и http://www.eng.yale.edu/EE-labs/morse/courses/ee226TP/robot/default.htm and once again type in "BASIC Stamp and the ADC0834" at www.google.com (http://www.google.com).и I saw quite a few articles there.

Connecting to the ADC0834 shouldn't be any harder than connecting to the ADC0832 -- give the attached example a try.

Note: I've posted the file with an added .TXT extension to allow online viewing.и When downloading, remove the .TXT extension so that it's easy to open in the BASIC Stamp IDE.

So i can tie both DI and DO to the same pin?

I haven't read the data sheet for your part, but yes, with the ADC0838, you can tie them together.

To be safe, put a 1k resistor between the BASIC Stamp and the ADC0834 -- see the ADC0832 schematic in this article:
