(...) For fun, with a second sensor you can make a gouvenor, which takes it speed from the track, and with a third motor you can change the gouvenor setting :-). It works reasonably with the ligth sensor as well. Then it is analog. But I found the (...) (25 years ago, 6-Jan-00, to lugnet.robotics.rcx, lugnet.trains)

Actually, additional to this, it seems to be caused by colouring of keywords.

(...) Maybe this was already posted: the color coding doesn't work for multiline macros. (because of that, I thought for a while that they weren't even legal in NQC!) thanks /Vlad (25 years ago, 6-Jan-00, to lugnet.robotics.rcx.nqc)

A few (Hah!) years ago we used to get that realistic slow train speed by running our Lionel "O" gauge and American Flyer engines on DC. We used an AC Gilbert rectifier that was a full-wave selenium unit. By adding a switch we made it be only (...) (25 years ago, 6-Jan-00, to lugnet.robotics.rcx, lugnet.trains)

(...) PWM stands for "pulse width modulation". The LEGO speed control changes voltage as you turn the knob. An RCX turns the motor on and off really fast but always supplies full voltage. So half speed is a 50% duty cycle of full power, rather than (...) (25 years ago, 6-Jan-00, to lugnet.robotics.rcx, lugnet.trains)

| | Emulating arrays in NQC
|
|
Hi all! as I promised earlier, I am posting the code I've written to emulate arrays. I tried to make it general, but it's difficult to do without compiler support. Right now it implements a 32 items array of 4 bit variables. It can be quite easily (...) (25 years ago, 6-Jan-00, to lugnet.robotics.rcx.nqc)

(...) I think 1 and 2 are the ones that would be really needed. 2 would be useful in writing macros to emulate arrays or "small" variables. But maybe there will be support for that in the compiler... cheers /Vlad (25 years ago, 6-Jan-00, to lugnet.robotics.rcx.nqc)

Hi Ben, I think I missed something here. What is "PWM mode"? What language are you programing in? And what is the "internals page"? Thanks so much for pursueing this!

Thanks for the reply, I really enjoyed your book. My son (age 13) also enjoyed it. He's starting out using ROBOLAB, but your book has sparked an interest in C (like) programming. I look forward to a sequel. (...) (25 years ago, 6-Jan-00, to lugnet.robotics, lugnet.robotics.edu, lugnet.robotics.rcx.robolab, lugnet.edu, lugnet.robotics.rcx)

As this is my first post to this newsgroup, I thought I'd start by saying how wonderful I think nqc is etc. I got the RIS 1.5 for xmas and had nqc up and running in no time on my linux system.
