Yes. We ran into similar problems when writing neural network code.
Persist- you can write really cool stuff on legOS- we did. Also, emulegos
(which is still around somewhere, though I'm not sure if anyone has ported
it to 0.2.x) would probably help debug, if you need some help there.
We were under a time crunch when we discovered our problems, so we never
did use it, but it can be a really useful tool.

| (...) Is this neural network code made public? I have emulegos, but I havn't much more than started it up. Do you know if it can handle IR-communication between several RCXs? Tobias (25 years ago, 21-May-00, to lugnet.robotics.rcx.legos)
