| | RcxCC for NQC 1.1?
|
|
I just downloaded RcxCC and noticed that it is still using NQC 1.0b4 Was the RcxCC project abandoned? Why it still uses an outdated version of NQC? Are there any other good alternatives to RcxCC for the new NQC? Thanks Laurentino Martins (...) (26 years ago, 7-Mar-99, to lugnet.robotics.rcx.nqc)

(...) I've checked into this a little further. It comes down to something like the following: void foo(const char *p) { delete p; } On one hand, this is conceptually a violation of "constness" as a caller to foo() wouldn't know that the object (...)

Thanks Dave, I did however find a version of Bison and Flex to use under windows. I didn't want to install the whole cygwin distribution so I searched and found stand alone versions of that came from DJGPP. I'm still having a few minor (...) (26 years ago, 4-Mar-99, to lugnet.robotics.rcx.nqc)

(...) You can probably use parse.tab.c instead. The whole default/parse.cpp thing is specific to Unix builds. The Mac and Windows builds are done under Metrowerks with custom Flex/Bison plugins. The output of those plugins is in nqc/lexer.cpp and (...) (26 years ago, 4-Mar-99, to lugnet.robotics.rcx.nqc)

I am thinking about porting NQC to Windows CE. The first thing I noticed was that the default parse.cpp file was missing from the source distribution. Also, has anyone already created a VC++ project file for NQC? I'd like to get a copy if it has (...) (26 years ago, 3-Mar-99, to lugnet.robotics.rcx.nqc)

| | Re: Making Light Sensor Passive
|
|
I'm not sure what you mean by "making light sensor passive". The light sensor, by design, requires power to work. You can tell the RCX that the light sensor is a passive sensor, but you don't get much range in readings - the phototransistor in the (...) (26 years ago, 25-Feb-99, to lugnet.robotics.rcx.nqc)

| | Re: One Big Program

Small misunderstanding... The RCX firmware contains a small interpreter which runs "RCX bytecodes". These are very different from H8 machine language. NQC generates code that runs within the interpreter, and asm statements just generate raw (...) (26 years ago, 23-Feb-99, to lugnet.robotics.rcx.nqc)

The thing to remember about legOS is that pretty much anything you can do in C (gcc, egcs) in 32k of RAM, you can do with legOS. I believe that both legOS and NQC have definite places in the RCX programming universe. I happen to have been using gcc (...) (26 years ago, 22-Feb-99, to lugnet.robotics.rcx.nqc)
