Hi, All ! I wrote a Windows 95/98/Me/2000 free software. This program named "Midi2Lsc" is SMF (Standard MIDI File) to LSC (LEGO Script Language of RIS2.0 SDK) and/or NQC translator. It is alpha test release status now. SMF format 0/1/2 support (...) (25 years ago, 28-Jul-01, to lugnet.robotics, lugnet.robotics.rcx, lugnet.robotics.rcx.nqc)

Hi Jeff; I think play for its own sake is generally misunderstood. It seem if you are not making something immediatley useful then what you are doing has no value! The value lies in the benefits of pure play. It certainly relaxes me. I view play (...) (25 years ago, 26-Jul-01, to lugnet.robotics.rcx)

Hi everyone, Someone asked me just the other day what good was playing with the Lego RCX. I quickly barked back that the RCX and NQC had taught me, a none programmer (well real world vs. Lego), a great deal about the essence of programming and the (...)

I saw some programs for a palm pilot that makes it a learning remote. They were used in the same way the Lego remote was: directly controlling the rcx. I was wondering if anyone had a link for the same thing for a pc/laptop... -Rob (25 years ago, 25-Jul-01, to lugnet.robotics.rcx)

(...) I am not sure if the USB serial ports work for all applications. You might want to be a bit careful. I have some older programs which expect to find real hardware COM ports and they don't recognise the USB variety. JB (25 years ago, 23-Jul-01, to lugnet.robotics.rcx)

Lego Mindstorms told me that USB to Serial converters have not functioned properly. The actual conversation went as, "they (the convertors) don't send correct information to the brick through the IR tower. There are no work arounds." I have been (...)

(...) There are external Serial ports that you can buy and plug into your USB ports. I would think that might be the easiest way to go. Eric Kingsley (25 years ago, 23-Jul-01, to lugnet.robotics.rcx)

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.. (...) (25 years ago, 21-Jul-01, to lugnet.robotics.rcx)

| | Re: Maximum sample rate (turn rate) for rotation sensor
|

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. (...)

Does anyone know the correct maximum sampling rate for the Lego rotation sensor?
