| | Transmission alternatives to IrDa ?
|
|
Hi, assume you want your PC to act as the brain of the robot. The PC should send from time to time comands to the robot during it works. The robot might be far away, so that IrDa transmission would not be possible anymore. Are there alternatives to (...) (22 years ago, 13-Oct-02, to lugnet.robotics.rcx)

Hello, According to John Hansens' instructions, I am assuming you do not need to download the bin-utils as called out in the original sourceforge instructions. Is this correct? Thanks again for the help. Here goes. Rick Bonari (22 years ago, 11-Oct-02, to lugnet.robotics.rcx.legos)

Hello, When I do a uname command, I get CYGWIN_98-4.10. It definitely appears that makefile.common has some problems with paths, etc. When I type the command: strip fontdesign.exe dll.exe makelx.exe fixdeps.exe genlds.exe firmdl3.exe as I mentioned (...)

Could you build a voltage controlled switch out of the RCX? Do this: Monitor a voltage, when the monitored voltage does something, switch a motor output. 1) What would you have to do to monitor a voltage (safely)? Connect an input sensor to your (...)

| | BrickOS issues
|

First off, I'd like to say that I had ZERO problems installing, building, and testing BrickOS on my PC. That's even with the BrickOS name change release and the pre-built Hitachi tools. You guys do good work! There are a few issues I have come (...) (22 years ago, 11-Oct-02, to lugnet.robotics.rcx.legos)

A big question is if the positioning resolution you could achieve would be worth the cost or effort. The GPS hardware I've seen tell you where you are within a few yards. Unless you can get that down to a few inches what's the point? Plus you still (...) (22 years ago, 11-Oct-02, to lugnet.robotics.rcx)

For sometime I have thought that a GPS interfaced with the RCX would be the answer to my navigational prayers. I have not found any information on an interface for the RCX (GPS-RCX or GPS-PC-RCX). I realize that this is not a trivial task with (...) (22 years ago, 11-Oct-02, to lugnet.robotics.rcx)

Rick, I have never used 'make strip' and have been using legOS/BrickOS for quite some time now. So, if it doesn't work, that should not stop you from continuing. However, with BrickOS, the make strip command now executes 'strip fontdesign.exe (...) (22 years ago, 10-Oct-02, to lugnet.robotics.rcx.legos)

Rick, It sounds as if you have gcc working, however, the version of objcopy that you copied from another folder is incompatible with the hitachi h8 version of gcc. You need to have a special version of objcopy that is designed for the h8 (the RCX). (...) (22 years ago, 9-Oct-02, to lugnet.robotics.rcx.legos)
