 | | Re: Library use in LegOS
|
| (...) Not sure of the details, but the linker takes the .o file, and the symbol file LegOS.lds, created during the kernel compile, and produces two files; .ds1 & .ds2, which are then passed to makelx to produce the lx file. So it seems the linker (...) (24 years ago, 27-Mar-01, to lugnet.robotics.rcx.legos)
| | | | | Re: .lx format
|
| (...) One other possibility is to not use the lx files at all - just stick to the srec format as (I think) LegOS used to (version 0.1.x?). A bit less efficient downloading the kernel all the time, but removes the need to dabble with lx format at (...) (24 years ago, 27-Mar-01, to lugnet.robotics.rcx.legos)
| | | | | Declarations in header files
|
| Hi! This is very technical, but: does the declaration of an "extern inline const void" function really make sense? GCC accepts it, but that is a VERY lenient compiler. An extern function should be definition not have a definition, and 'const void' (...) (24 years ago, 27-Mar-01, to lugnet.robotics.rcx.legos)
| | | | | Re: .lx format
|
| (...) So in effect, it is dependent on the gcc loader mechanism. Ungh! The idea of using two symbolsrec files: one could be kernel, the other the program. Would make sense for kernel call resolution. (...) I looked at it, and it mainly outputs (...) (24 years ago, 27-Mar-01, to lugnet.robotics.rcx.legos)
| | | | | Re: Library use in LegOS
|
| (...) OK. How are the calls to the kernel resolved? By the makelx program, or by some magical stuff in the linking. I can imagine compiling the kernel, getting a symbol table out, and then when compiling user programs, you use a linker DEFINE or (...) (24 years ago, 27-Mar-01, to lugnet.robotics.rcx.legos)
| | | | | Re: New Group?
|
| As the author of GBP I get 3 or 4 emails a week about it and there have been 9,647 hits (I just checked) or the download page since I installed the counter about a year ago. My only problem with the idea of setting up a GBP group is that it might (...) (24 years ago, 27-Mar-01, to lugnet.robotics, lugnet.robotics.rcx)
| | | | | Re: The sound of train
|
| I don't have any specifically for trains, but my crane has a two-tone warning sound - you can find the programming info at (URL) The warning sound is generated by RCX1. I'm not sure how difficult it will be to translate this into NQC, but basically (...) (24 years ago, 27-Mar-01, to lugnet.robotics.rcx, lugnet.trains)
| | | | | Re: The sound of train
|
| Thanks. Could you show me legOS source? (both steam and diesel), I have no idea about music or sound. I can convert it to NQC, what I am using NQC is that I want to make all my programs that can be used both by RCX and Scout. Zhengrong (...)

| | | | | Re: The sound of train
|
| Your original post mentioned "warning or alert". Are you looking for train sounds, or warning sounds? The train sounds that Sonnich is talking about is actually the puff-puff of a steam engine, and would be very difficult to duplicate with the RCX, (...)
