In article (...) 650 ticks per second works out to about 1.5 ms per tick. I didn't think the RCX sampled inputs that fast - I thought it was 3.0 ms per sample. If so, this would mean that the RCX is capable of adding 2 to the rotation value during a (...) (25 years ago, 13-Jul-99, to lugnet.robotics)

(...) Nope-it's not. I use LegOS, and that only adds 1- I know that particular section of code inside and out. Therefore, it must be the sampling time. Or a really egregious error on my part.

In article (...) I don't know anything about legOS - perhaps it has its own sensor sampling code. I was looking through the standard Lego firmware to determine the 1250 rpm number, and I verified it with a few experiments, but again using standard (...) (25 years ago, 14-Jul-99, to lugnet.robotics)

(...) Ah! I thought the 3 ms you were referring to was a function of the hardware, not the software- I thought it might have something to do with the A-to-D in the chip. FYI, in legOS, the rotation sensor can technically be sampled as often as the (...) (25 years ago, 14-Jul-99, to lugnet.robotics)
