[oopic] Re: Using ultra sonic sensor with the oopic

The sensors can't be connect to the 31 Digital I/O lines and
communicate with PW or RX?

If I was to go with the A2D lines could I add a extension module to
get more then 7 (I was thinking it was only 4)?
Is there any example code on how to program using A2D?

Thanks for your help.

communicate? Would I need the expansion module to do this?
