| As an addendum to my light message, I checked direct-sensor.h, and the numbers there seem to work out just fine. Could this be a compiler problem on my part? Just another thought- Luis ###...### "They call the faithful to their knees to hear the (...) (25 years ago, 12-Apr-99, to lugnet.robotics.rcx.legos)

|
| Another question before I call it a night- under LegOS 0.1.6, light-sensor values were restricted to the range 0-100. Under 0.1.7, I'm now getting a max value (pointed straight at a light bulb) of about 263, or once even 272. 255 would make sense to (...) (25 years ago, 12-Apr-99, to lugnet.robotics.rcx.legos)
| | | | | Updated Win32 toolchain
|
| I've put an updated Windows 95/98/NT H8/300 cross-compiler, based on EGCS 1.1.2 (basically, the EGCS 1.1.2 release plus Mumit Kahn's Win32 patches, plus a couple of source hacks), on (URL) - this time, I've bundled in enough to compile without (...)

| Thanks, Kekoa. (...) Well, as it appears I don't have much of an option, I'll stick to ints then :-) -Luis ###...### "They call the faithful to their knees to hear the softly spoken magic spell:" "There's no place like home...

| | | | | Re: floats
|
| (...) The errors you see are due to the fact that there is no hardware support for floating point. The compiler substitutes calls to the software equivalents, which do not exist; hence the linker errors you see. The math routines that do exist are (...)

| | | | | floats
|
| When I try to use a float in my code, I get a compiler message somewhere along these lines: <begin error message> ../code/light-brait....t-brait.c: undefined reference to `__floatsisf' ../code/light-brait....t-brait.c: undefined reference to (...)

| (...) legOS has a software solution built-in - when you are ready to quit, hold down the on/off button and press the 'prog' button. Hope this helps! Cheers, Richard (25 years ago, 9-Apr-99, to lugnet.robotics.rcx.legos)
| | | | | Web based LegOs compiler for the underprivileged?
|
| I recently downloaded a program for the palm pilot that displays up to date movie times and locations based from perl parsed data from movies@yahoo.com It is a great program, but getting and setting up Perl on my system was a real pain. Luckily (...) (25 years ago, 8-Apr-99, to lugnet.robotics.rcx.legos, lugnet.robotics)

| (...) I skipped something here. The assumption I made is that you want to load new custom firmware. If you want to load the Lego firmware, find the Firm0309.lgo file in your Mindstorms directory, and load that into the RCX exactly as you would (...)

|
| (...) I belive LegOS breaks firmware deletion, in the sense that the "delete firmware" opcode is not supported by the IR routines, but I could be wrong about that. If you are using an AC adapter and no batteries, the easiest thing to do is to turn (...) (25 years ago, 8-Apr-99, to lugnet.robotics.rcx.legos)
