 | | Getting the Windows LegOS 0.2.3 compiler package to compile 0.2.4
|
|
I have been using Rossz Vámos-Wentworth's LegOS 0.2.3 distribution for Windows and it works beautifully. I was wondering if anyone has had any luck getting the new 0.2.4 release to work under this Windows distribution of LegOS? I copied the entire (...)

In my latest and greatest idea I intend to run two RCXs together to control a fairly complicated arm. To do this I need to communicate with two RCXs from my PC (the program is actually going to be controlled from my PC). Now I haven't had much luck (...)

(...) I usually just pull out a battery for a second. Note that the RCX draws very little power when turned off, and thus can retain memory for a while even without any batteries (cacitance on the power supply rails hold the RAM for a while).

(...) You turned it off in between and by only having your mm.c patch zapped parts of legOS own memory. No program will survive an off/on with only your patch in 0.2.4. Eddie C. Dost ecd@skynet.be (24 years ago, 1-Aug-00, to lugnet.robotics.rcx.legos)
