(...) Yep - I thought so...for things like cameras where these things are in common use, the need is only to know the range to the nearest object. I don't even know if the other things (multiple object detection and size/reflectance estimation) are (...) (23 years ago, 6-Feb-02, to lugnet.robotics)

(...) let (...) Thanks for that Steve. My circuit will be based on the latter of the two possibilities. It is based on a design by RA Penfold from Electronics and Beyond (Sept.2001) so I'm basically doing construction by numbers! However, the thesis (...) (23 years ago, 6-Feb-02, to lugnet.robotics)

Hi all, my name is Francis (from Spain). I've read Extreme MindStorms and I decided to put my hands on and build some new sensors. I began with the optointerrupter, but have a little trouble. When I connect the sensor to the RCX I can't get a stable (...) (23 years ago, 6-Feb-02, to lugnet.robotics)

(...) I guess the first question I'd ask is "What interface does the sensor present to the RCX?" I imagine there are two possibilities: It could be a raw interface that let you send an acoustic "PING" on command and read a voltage back telling you (...) (23 years ago, 6-Feb-02, to lugnet.robotics)

Now that my interest has been piqued by the multiplexer problem (and sensing problem in general), what would some of you hardened embedded/real-time system veterans recommend for reading on the subject. Two books that I've found at Amazon.com are (...) (23 years ago, 6-Feb-02, to lugnet.robotics.rcx.legos)
