 | | Strange problem with RcxCC ??
|
|
I have used RcxCC on several Win95 and WIN98 and WIN Me machines. Great. But now I need to run it on 6 machines in a library for a class. I have installed the same latest version on 3 of these machines, and they all seem to install OK, but executing (...) (24 years ago, 14-Feb-01, to lugnet.robotics.rcx.nqc)

Thanks for the replies, and for the sample programs. I'll try them out soon. I'm building a robotic arm (that's why I chose to reply to this message, not the other, later ones) that I plan to program in NQC. It does not need multitasking to work, or (...)

(...) Sorry Juergen, but that's not quite right. You can start and stop tasks as often as you wish to do. like this int do_s_s = 0; int condition = 0; task main() { while (1) { if (condition && !do_s_s) { start do_something_special; do_s_s = 1; } if (...)

Hej Tobias! (...) No, rather you need a While or Until loop. Normal programming languages are different from the RCX code. In RCX code the watchers are running all the time, in NQC you need to program the repetition yourself. A program for simple (...) (24 years ago, 6-Feb-01, to lugnet.robotics.rcx.nqc)

Tobias, 'multi-tasking' means that several tasks run simultaneously. For example, a robot arm could grab, lift and swivel, one after the other, as functions, or simultaneously, as tasks. Or, the RCX could play a tune and a walker could walk, one (...) (24 years ago, 5-Feb-01, to lugnet.robotics.rcx.nqc)

I've downloaded NQC, and got it running. I have been able to make the motors run, to make them run backwards, then forward, etc. However... I can't get the sensor thing to work right.
