Some of you may have heard of my WebSpirit, well, I've taken in, improved appearances, cleaned up some code, and moved it to my domain. Cybermaster support is planned. Please note, this does not control anything on my computer! I don't know about (...) (25 years ago, 25-Sep-99, to lugnet.robotics, lugnet.robotics.rcx)

|
(...) Cool, that'd be great. What I'm looking for is: nqc -listen and then all IR messages sent by the RCX via SendMessage would get dumped, one per line, in decimal, to stdout. Additional parameters could make the format be comma-delimited, (...) (25 years ago, 24-Sep-99, to lugnet.robotics.rcx, lugnet.robotics.rcx.nqc)

(...) You can sometimes fake it by sending "bad" codes in -raw mode with verbose mode turned on (-v) and a long timeout (-t). For example, to examine the Lego remote codes I kept typing this: nqc -v -t 2000 -raw 10 Since I didn't have an RCX around (...)

(...) If I understand you correctly, then this is more difficult than it sounds, because the IR tower shuts down after a few seconds after the PC stops transmitting. Things work fine if the PC initiates a conversation (e.g. by asking the RCX to send (...) (25 years ago, 23-Sep-99, to lugnet.robotics.rcx, lugnet.robotics.rcx.nqc)

I know that NQC can send IR messages; can it -- or any other command-line program -- listen to the IR port and dump any incoming messages to a file (or stdout)? (25 years ago, 23-Sep-99, to lugnet.robotics.rcx, lugnet.robotics.rcx.nqc)

| | NQC mentioned in Swedish technical weekly!
|

Hello! When reading this week's 'Ny Teknik' (New Technic), a weekly magazine for engineers, I found a short note about NQC. The article is about Lego Mindstorms, which is just about to be released here in Sweden, and the last part of the article (...) (25 years ago, 23-Sep-99, to lugnet.robotics, lugnet.robotics.rcx.nqc)

A bug in the document. * and / are legal for any expressions. % is restricted to constants. I know the restrictions are confusing. The problem is that the RCX opcodes are somewhat incomplete. Now that I think about it, I can probably generate (...) (25 years ago, 23-Sep-99, to lugnet.robotics.rcx.nqc)

| | NQC 2.0 and some math questions
|

Dave, You state in your documentation that * / and % can be used on constants only, but your example has x * Y in it. What is it that you mean? Does this mean that one can only do a y = 5*4 using these math routines? Does this mean that, for (...) (25 years ago, 22-Sep-99, to lugnet.robotics.rcx.nqc)

First beta had only one bug, and second beta seems stable, so NQC 2.0 is finally released. Actually, a lot of the delay was because I was wrapping up the documentation. For more information, see (URL) Baum (25 years ago, 22-Sep-99, to lugnet.robotics.rcx.nqc, lugnet.robotics)

Or at least two RCXs. (Thanks Jeff.) Now, with the aid of my friend Paul and his mindstorms set, it's time to go about implementing Pong. (25 years ago, 22-Sep-99, to lugnet.robotics, lugnet.robotics.rcx)

It usually takes about 200us or so to "see" the incoming 38KHz signal, common I suppose for an integrator to react to the signal getting through the band-pass filter, then a Schmidt trigger (...)

There was a bug with #include for files using MSDOS line endings in NQC 1.0b1. I'm pretty sure RcxCC beta 3.0 used this version of NQC.
