  Re: Swan Firmware
 
(...) what is the swan firmware? what have I missed? Thomas (20 years ago, 4-Jan-05, to lugnet.robotics.rcx.nqc)
 
  Re: Today's Challenge
 
(...) Your apologizing to be a teacher is accepted ;-) However, you must not apologize to work with ROBOLAB ! Anybody who followed the development of great LEGO robots has seen that ROBOLAB allows easy programming from beginners to absolute (...) (20 years ago, 4-Jan-05, to lugnet.robotics.rcx.robolab)

Five: -If you're not, participate in a local LUG or organization that has regular robotics challenges, etc. Calum (20 years ago, 4-Jan-05, to lugnet.build, lugnet.people, lugnet.people.newbie, lugnet.people.teens, lugnet.robotics.rcx.robolab)
 
  Re: What does RCX stand for?
 
(...) according to the RIS 1.5 user guide in German and French, it is "Robotics Command System". Thomas (20 years ago, 4-Jan-05, to lugnet.robotics.rcx)

  Today's Challenge
 
A cry for help: I am trying to implement Ben Williamson’s Fetchbot (URL). I am happy that I have the mechanics right. The problem is that I want to emulate Ben’s code in Robolab. (Yes, there are reasons I use Robolab which include me being a teacher (...) (20 years ago, 4-Jan-05, to lugnet.robotics.rcx.robolab)
 
  Re: questions on events
 
(...) This is where you use the event fork(s) that you asked about in a different message. You nest these forks to determine which event has been triggered. (...) Robolab is just a LabVIEW program. Viewed in that context, it is an amazing bit of (...) (20 years ago, 3-Jan-05, to lugnet.robotics.rcx.robolab, lugnet.robotics.rcx.nqc)
 
  Re: questions on events
 
(...) Yeah, my fault. I said two things that do not have to follow. Yes, you can use one event monitor to watch more than one event... and yes, you can't nest event monitoring statements. I've not used an event watcher to monitor more than one event (...) (20 years ago, 3-Jan-05, to lugnet.robotics.rcx.robolab, lugnet.robotics.rcx.nqc)
 
  Swan Firmware
 
I have installed the new Swan Firmware via Brixcc 3.3.7.8 using standard nqc coding works ok. I'm having problems trying to include any of the new code. Question 1 How do we use the Swan.nqh file Question 2 Can we use the new variables defined in (...) (20 years ago, 3-Jan-05, to lugnet.robotics.rcx.nqc)
 
  RE: Formula container?
 
Ok, I got it... Thanks to the Tufts site. (URL) is kind of odd that the navigation is to "create ---> constant"... "constant?" Hmmm... -- E (...) (20 years ago, 3-Jan-05, to lugnet.robotics.rcx.robolab, lugnet.robotics.rcx.nqc)
 
  RE: Define Event icon...
 
(...) Hi Jerry, Event Handling can be a long chapter to talk about. I am sure you will find a more well-explained chapter in some OS or just language book such as C++, or even in Java. Briefly speaking, event is a piece of real time information, (...) (20 years ago, 3-Jan-05, to lugnet.robotics.rcx.robolab)
 
  Formula container?
 
I am trying to compare the light value of two sensors, namely s1, & s2 . I don't want to go through the long route which is to save the light values from different sensors to different container, then, compare them. How about using "formula (...)

  RE: questions on events
 
(...) Hmm..., notice that the start monitoring icon allows to watch for multiple events within the same task. If each task can only monitor a single event, that feature being there does not quite make sense. (...) This is why I suspect the "event" (...)

  RE: Define Event icon...
 
Yes, Tom. This is exactly what I was trying to do... To trigger an event when it becomes 3. Great! Thank you very much! Cool! (...) (20 years ago, 3-Jan-05, to lugnet.robotics.rcx.robolab, lugnet.robotics.rcx.nqc)
 
  Re: Define Event icon...
 
(...) The condition of being equal to 3 is not an event. However, the action of transitioning to 3 is. I'd use the "set up normal event" command followed by the "define event" command. Set the upper threshold to 4, the lower to 2, and the duration (...) (20 years ago, 2-Jan-05, to lugnet.robotics.rcx.robolab)
 
  Re: questions on events
 
(...) See previous post for the "I-don't-actually-do-Robolab" disclaimer, but, since Robolab & NQC both work on the same firmware... You can monitor multiple events, but only in *different* tasks. In other words, (to my knowledge) you can not "nest" (...) (20 years ago, 2-Jan-05, to lugnet.robotics.rcx.robolab, lugnet.robotics.rcx.nqc)
 
  Re: Define Event icon...
 
(...) I fear I became very frustrated with Robolab, so can't help you *specificly* with that enviroment, but... at a firmware level, events can "watch" several different sources: sensors, timers, three simple counters... however, they can not be (...)

  Re: Define Event icon...
 
(...) Elizabeth, you are a few steps ahead of me in working with 'Events'. Could you explain, in plain English, what exactly an 'Event' is? ...it's not a 'State' because it can be a constant or a variable. Yet you can have an 'Event Fork' which is (...)

  Define Event icon...
 
Hi I'd like to set up an event to watch for a containers value = 3. I am trying to use the "Define Event" icon, but has no luck yet. Just wonder if there is anyone out there has suggestion. The official doc does not explain much different from what (...) (20 years ago, 2-Jan-05, to lugnet.robotics.rcx.robolab, lugnet.robotics.rcx.nqc)
 
  questions on events
 
Are events stackable? Or it works more like "signal()", e.g. in C? e.g. I have 2 different light sensor events set to watch for value higher than 42, yellow & blue. Let say both sensors read 45 at the same time, RCX returns only one event being (...) (20 years ago, 2-Jan-05, to lugnet.robotics.rcx.robolab, lugnet.robotics.rcx.nqc)
