|
| (...) 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)

| 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)

| | | | | 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 (...)

| (...) 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: 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)

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 (...)

| (...) 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 (...)

| 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.

| | | | | 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)

One of the first changes I made when I took over NQC was to add the ability for NQC to (...) (20 years ago, 29-Dec-04, to lugnet.robotics.spybotics, lugnet.robotics.rcx, lugnet.robotics.rcx.nqc)

| | | | | RE: Motor Speed Control

| (...) :) (...) I'm not sure how the Swan firmware does it, but I have mine set so it cycles every 8 ms. It's on for 0 to 8 ms, then off (brake) for the rest, depending on the speed. That's fast enough to produce a very smooth result. There is no (...) (20 years ago, 30-Nov-04, to lugnet.robotics.rcx.nqc)
| | | | | RE: Motor Speed Control

Now, if the resolutiion of timing for the brake (...) (20 years ago, 30-Nov-04, to lugnet.robotics.rcx.nqc)
| | | | | RE: Motor Speed Control
|
| (...) Yes, but I think the "power" portion of the cycle will draw more, because it's always trying to go from stop to full speed. Like driving a car with the brakes on. Start with the brake totally pressed, and the more you push on the gas, the less (...) (20 years ago, 30-Nov-04, to lugnet.robotics.rcx.nqc)
| | | | | RE: Motor Speed Control

| (...) The brake function (as far as I know) should not use more battery power as the short circuit is in the driver chip itself. The drivers are MOSFETs, so setting the H bridge to brake does not actually apply any battery power to the motor (...) (20 years ago, 30-Nov-04, to lugnet.robotics.rcx.nqc)
