Cool, thanks I was able to find the doc here: (URL) post about the motor seems helpful, so if I understand right the way to run motor A forward would be "mov 0x030003,r0h mov 0x80,r0h" and for the motor C the same except 0x06? How does the (...) (21 years ago, 17-Jul-03, to lugnet.robotics.rcx, lugnet.robotics.rcx.legos)

Here's a more direct link for the H8 docs: (URL) down to the literature section and download the two PDFs. For assembly, I would recommend starting off with an installation of BrickOS and perusing the various source code files for the kernel. You'll (...)

I was interested in writing some assembly code for the lego mindstorm, I don't plan on writing an incredibly complex program though. I am learning asm for the z80 chip so I have a little experience. I only want a single threaded application with one (...) (21 years ago, 16-Jul-03, to lugnet.robotics.rcx, lugnet.robotics.rcx.legos)

Mark, Good information. I was wondering what else got powered down by that bit. Once again, I think we need to take a moment to think about what life would be like without LUGNET. Just having those old archives to look through can help save a large (...) (21 years ago, 30-Jun-03, to lugnet.robotics.rcx)

Hi, While delving into the nitty gritty details of the RCX's power off routine, which was discussed a *long* time ago in these threads: (URL) the very low message numbers... :) I noticed that in addition to putting the RAM into low power mode, port (...)

Hi, I've writen a program to send messages to an RCX, depending on programable key strokes. My idea was to drive the robot "blindly", relying on standard firmware messages and replies.

Is it possible to reserve a particular RCX variable using NQC and then access it from within the program? And is using SetVar() the correct/best way to send a variable to the rcx using VB/spirit.ocx? I'd also like to know if their are any online (...) (21 years ago, 25-Jun-03, to lugnet.robotics.rcx)
