external A/d converter

[Knightlord]

Hi
I am trying to hook up an external A/D converter LTC1598(supports SPI)
I have never done any serial communication
can anyone help me into how to hook it up and how to control it?

thanks

The datasheet shows you how to connect it to a controller, and logic values for channel selection.

You should be able to modify this http://www.microengineeringlabs.com/resources/samples/x1/pbp/spix.bas to fit your application.

Here's another link with PBP code for use with similar LTC IC's.

That should be enough to get you started.
