About photocells... I did this once and used some of the stuff that Rodney Brooks et al were working on with subsumption to build the ultimate "bug". It was a tiny cockroach type robot with a small FM wireless microphone strapped to its back. The (...) (28 years ago, 20-Jun-96, to lugnet.robotics.handyboard)

(...) It seems as if your unwanted light is mostly going to be coming from above your bot. It also seems that the tubing that you have around the photocells has made the light detection too directional. (Is that what you want?) With the two cells on (...)

I'm experimenting with photocells, and I'm looking for some feedback from anyone who's got some insight or experience with this sort of thing. Essentially, I have two photocells, both facing forward, on the left and right side of my robot. I'd like (...) (28 years ago, 19-Jun-96, to lugnet.robotics.handyboard)

| | SPI newbie question
|
|
Forgive the newbie question, but I have an assembly program developed for the 6811 EVB that uses the SPI which I'm trying to rewrite in Interactive C for the Handyboard. However, I'm not sure if or how IC can access the SPI. I just need the SPI to (...) (28 years ago, 18-Jun-96, to lugnet.robotics.handyboard)

(...) It seems like this might be a good thing to do - create a document of all of the pcode bytecodes. Another thing that might be usefull is a document describing the serial line protocal that IC uses. I have had need for both of these in the (...)

(...) If you're interested in learning what the various pcodes do, or in making a new development environment which backends to the pcodes, I'd recommend looking at "pcodesim.c" in the libs directory of the IC sources. This is a fairly (...) (28 years ago, 17-Jun-96, to lugnet.robotics.handyboard)
