  Rotaion Sensor Sampling Speed?
 
Hi all, I'm putting together a mazebot for Mindfest, and ran into a bit of a funny with the rotation sensor. I THINK it has to do with the sample speed, but I'm not positive. I'm using pbFORTH and sampling the rotation sensor in a tight loop. The (...) (25 years ago, 14-Oct-99, to lugnet.robotics)
 
  Re: Rotaion Sensor Sampling Speed?
 
Ralph, I don't know about the specific issues with pbForth, but this summer I was working on a large gear train (for a problem that we have recently "proven" is computationally intractable for the RCX) and dropped about 20 counts out of every 1,000 (...)

(...) Well, I'd need to vibrate things while looking at raw values, which is possible, I guess. I could run the gantry, smaple as long as possible and then store the value in an array... Something like: CREATE BUFFER 5000 CELLS ALLOT ( makes room (...) (25 years ago, 14-Oct-99, to lugnet.robotics, lugnet.robotics.rcx.pbforth)

(...) I thought the problem was that it vibrated itself? (...) <snip forth code, which looks cool :)> (...) Take a look at the code that Markus sent out a while ago with the new firmdl he cooked up, particularly the code in keepalive.c and the code (...)
