 | | 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)

| (...) (URL) Is a note I posted a while back on pbForth speed. It really is very fast - not as quick as legOS, but fast enough for what we're doing. In fact, NQC and native firmware is fast enough - we just don't have enough variables.... As a point (...) (24 years ago, 6-Oct-00, to lugnet.robotics)
