(...) There are indeed many ways to skin a cat...in the end , the effect is the same, but I'm always curious to see how others do things.

Actually, whils I am re-coding things, is there any reason why you didn't do DELAY like this? : DELAY ( 100msec timer -- ) 0 OVER TIMER_SET SWAP ( timer ticks ) BEGIN OVER TIMER_GET OVER > ( timer ticks time>ticks ) UNTIL 2DROP ; I have produced an (...)

(...) That is what I intended them for, I just thought that if I put them up here it would save some typing for someone else.

This would almost have to be a UDP like protocol just because the RCX has such limited resources and the complexity of adding transmision control to the protocol would be nasty. I really hate news groups, I like having messages sent to me directly. (...) (27 years ago, 15-Apr-99, to lugnet.robotics.rcx.legos)

I need some help with legOS and rotation sensors. I compiled and downloaded the demo/rotation-sensor.c program. The behaviour I get on my RCX is not what I expected. When I turn the sensor clockwise, the LCD toggles between 0 and -1, while (...) (27 years ago, 15-Apr-99, to lugnet.robotics.rcx.legos)

(...) Alas, I only used the firmware timers available as core RCX firmware calls. I can look through Kekoa's disassembly to see if there are higher resolution timers available ( I think the motor timers might be useful ) In general, NQC hooks in (...)
