[chbot] DIP package ADC chips?

[Carl Ranson]

I've managed to get one of these chips (MCP3304) going.

A bit of study on the data sheets, and I was able to find a similar chip 
which already had code on the propeller object exchange, although it had 
a different number of bits and channels. Still, modifying someone elses 
assembler is a lot easier than writing your own.

I wanted to give a shout out to Hanno. His Viewport tool was a big help 
in visualizing the inner workings of the software on the propeller.

thanks all for your suggestions
