(...) Exactly. Can you say "make config"? Ah, no, that won't do. "make menuconfig", maybe? We'd have to stay portable, though. That rules out "make xconfig" :-( (26 years ago, 22-Mar-99, to lugnet.robotics.rcx.legos)

How about a ./configure script? It just needs to ask two questions... write the answers in .config or Makefile.common or whatever suits your fancy and you're done once and for all. (26 years ago, 22-Mar-99, to lugnet.robotics.rcx.legos)

| | Reworked Scheduler
|
|
I have gotten my scheduler changes to work. There is a patch against 0.1.7 on my legOS page ((URL) will apply most of the way against 0.1.6, but there are some bits that you will have to apply by hand due to differences in comments. I wouldn't be (...) (26 years ago, 21-Mar-99, to lugnet.robotics.rcx.legos)

|

Hi: I would like to build a lego scanner using a single light sensor. I have found a number of sites which explain how to build them, however, I could use some assistance with how to convert the data collected into an actual image map. I understand (...)

I finally got my scheduler working on 0.1.6. Porting it to 0.1.7 wasn't too painful. But when I tested it (I have been testing with demo/tm-and-ir), I found that there is junk (not necessarily alphanumeric characters) displayed on the LCD. Thinking (...)

|

Sorry I'm late. I believe this is not an issue with legOS. legOS only calls the ROM powerdown function at the end of its kmain() loop, where the stack pointer should be in the on-chip RAM area anyway. When sleeping in the idle task, legOS directly (...) (26 years ago, 20-Mar-99, to lugnet.robotics.rcx.legos)
