|
| Quoting Ed Manlove (emanlove@ieee.org): (...) I can't speak for absolute certain about this, not being familiar with that part of the code, but sort -u is used to unique a list of strings. That is, if you pipe a file: spam spam spam eggs through (...) (23 years ago, 8-Mar-02, to lugnet.robotics.rcx.legos)

| What is the sort command doing in the command to create *.map files within the Makefile.kernal? # how to make map files %.map: %.coff $(NM) $*.coff | sort -u > $*.map Doing my build I get the following error and the resulting map file has size zero.

| | | | | binutils?
|
| when i first got legOS up and running i used rcx-egcs-1.1.2-1.i386 rcx-egcs-c++-1.1.2-1.i386 rcx-binutils-2.9.5.0.22-1.i386 i'm assuming the first two are the c and c++ compilers, however what is the function of the binutils? thanks (23 years ago, 7-Mar-02, to lugnet.robotics.rcx.legos)
| | | | | backing up programs
|
| Hi, I have a couple of RCX's and was wondering if anyone has done any work on a way to transfer a program from one rcx to another in the case of a battery failure, etc. instead of replacing the rcx in the robot with the other one. thanks (23 years ago, 7-Mar-02, to lugnet.robotics.rcx.legos)
| | | | | Re: exponents, e^
|
| i tried the lejos environment and found the exponent and trig functions worked very well. and they work with doubles. so if anyone is having trouble with using trig, log, exp functions in legOS, you might want to try lejos. plus it was easier to (...)

| | | | | Re: exponents, e^
|
| (...) Only one I can think of off-hand is support for the remote control, I've been thinking about looking at that if I can get some time (though it's still only a patch in legOS, have to do something about that, too). There may be others I don't (...) (23 years ago, 6-Mar-02, to lugnet.robotics.rcx.legos)
| | | | | Re: exponents, e^
|
| you know i was looking at lejos, java for RCX, and it seems to have exponents, trig, etc. functions built in. any advantages legOS has over lejos i don't know about. if not, i think i may give it a whirl.... -dave (...) (23 years ago, 6-Mar-02, to lugnet.robotics.rcx.legos)
| | | | | Re: exponents, e^
|
| Dave I am working on a number of maths functions that includes loge log10 expe and exp10 x^y as well as trig functions. As you note it requires the specification of the mantassa and exponent desciption of the float variable for the RCX. Usually this (...) (23 years ago, 6-Mar-02, to lugnet.robotics.rcx.legos)
| | | | | exponents, e^
|
| hello, i've searched through the discussions but i haven't been able to find any info on using floats with exponents in legOS, specifically the inverse of natural log: e^. actually, i can't find any info about integers with exponents either. i am (...)
