I guess I have a really simple question to ask... I know that I can
share many of the lines off of the SPI in order to hook up two polaroid
sensors... However, is it really necessary to add a diode to each of the
ECHO lines? If so, what are the specs for those diodes? I am basing the
fact that I can use D3 for the additional INIT line for the second
sonar. IS THIS CORRECT? I would not like to just chuck and jive with
this, it is of course university property. I would like the reply to go
to my account directly cause I don't know when Fred will get me added to
the mailing list... Thanks
Ian
