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

The easiest way to do this is to use the analog output of the MAXSONAR
unit and trigger them in sequence so you don't have interference. The
most straightforward way is to give each SONAR its own A2D line - With
the ooPIC you can have up to 7 A2D lines. With buffer resistors from
each SONAR you might be able to connect all of them to a single A2D if
you really needed to, but you'd have to experiment with that resistor
value and how fast you could switch units.

What I was wondering is it possible to connect this type sensor to the oopic digital I/O pins. The sensor supports PW RX, etc. How would I communicate? Would I need the expansion module to do this?
