Hello, Well after a week of head beating, cursing, downloads and chicken waving AND a great deal of help from Max Bowsher (this last bit was actually the most useful :-) I finally have legOS up and running with the above setup. Had I followed Max's (...) (23 years ago, 21-Jul-01, to lugnet.robotics.rcx.legos)

Dave and Luis, Thank you both for the information. I'm big admirer of the work you've done for the RCX community. (...) I see. (60/0.003)/16 = 1250 And if you were worried about the Sampling Theorem you would divide that in half just to be sure.. (...) (23 years ago, 21-Jul-01, to lugnet.robotics.rcx)

When using the standard firmware, sensors are sampled every 3 ms. The rotation sensor uses a quadrature encoder with a 1:4 gearing between the axle and the encoder, so there are 16 "ticks" per revolution of the axle. The decoding routine in the (...)

The hardware can actually do (in my testing) up to ~3000 rpm with good accuracy. The problem is with the standard software, which cannot do more than some low number (which may or may not be 500, I don't recall) because of how it samples the HW. (...)
