Hello everyone. I finally got everything cool with the Handyboard I'm using in terms of the software and loading it and getting all connections right.

A while back I asked if anyone knew about a socket to accomodate the 9-pin plugs that come with the Polaroid sonar modules. I feel pretty dumb now, because I talked with the people at Polaroid, who tell me that it's not really a plug at all; it's (...) (27 years ago, 16-Mar-98, to lugnet.robotics.handyboard)

(...) If I am understanding you right... I haven't looked at the encoder routines yet, but I am assuming encoder0_counts is global. Why not, just omit the pointer count from the _encoder struct and just use the global, since you already have it? (...) (27 years ago, 15-Mar-98, to lugnet.robotics.handyboard)
