 | | swan firmware motor problem
|
| Hi, I trying out the Swan firmware (Fast0103.lgo) with nqc 3.1 r4 but for some reason the motors won't turn on. Has anybody seen something like that? If I run the program, it does all the other things, even switch on the little motor triangles on (...) (18 years ago, 9-Aug-06, to lugnet.robotics.rcx.nqc)

|
| Anyone know when Lejos will be ported to the NXT? Just got my kit and looking forward to it! (18 years ago, 9-Aug-06, to lugnet.robotics.rcx.java)

| (...) I can't think of why not. Sample the light sensor, then send an IR message, then sample the light sensor very shortly afterwords. Compare those two light sensor readings: if the second is much greater than the first, there's something (...) (18 years ago, 7-Aug-06, to lugnet.robotics.rcx.robolab)

|
| Proximity detections in ROBOLAB? It is possible to use the IR port on the RCX for proximity detection in NQC but I can'y find a way to do the same in ROBOLAB - is there anyone that has done that? You send messages from the RCX and use the (...) (18 years ago, 7-Aug-06, to lugnet.robotics.rcx.robolab)

|
| There has not been a great deal of public discussion about having a Great Ball Contraption at BrickFest '06, but there WILL be a GBC at BF06. If you missed your chance last year, when we had almost fifty modules, now is the time to start building. (...)

| | | | | RIS Installer Problem
|
| I would appreciate any help - I'm not sure this is the best place to post this but I need to get in touch with software-experienced people and this looks like a good start. If I should post this elsewhere, please let me know. If anyone has some (...) (18 years ago, 26-Jul-06, to lugnet.robotics.rcx)

|
| Hi Mark, (...) probably, I guess they would be started within the same millisecond, which would result in synchronized wafeforms. (...) It's not that bad, when the waveform is off the motor is floating. So the power control will be ineffective at (...) (18 years ago, 23-Jul-06, to lugnet.robotics.rcx)
| | | | | Re: parallel RCX outputs
|
| (...) The flashing is a feature of the 1x2 and 1x4 lamps... if run in one direction, it's solid, but in the other it flashes. This comes from the old light and sound sets, where you might well want a flashing light. You're right that the two outputs (...) (18 years ago, 23-Jul-06, to lugnet.robotics.rcx)
| | | | | Re: parallel RCX outputs
|
| (...) If all motor ports are started and stopped together, does that synchronise the PWM waveforms? If not, then I don't recommend paralleling up. If so, then I recommend paralleling up only when motors are started and stopped together and are run (...) (18 years ago, 23-Jul-06, to lugnet.robotics.rcx)
| | | | | Re: parallel RCX outputs
|
| Hi Chris, (...) I think so (warning, this is based only on theoretical knowledge). (...) That should be ok. Setting the power level might not work correctly, from looking at the ROM code it seems the PWM waveforms are not synchronized. Now comes the (...) (18 years ago, 22-Jul-06, to lugnet.robotics.rcx)
