 | | gdb & legOS
|
| Hi All. I've been thinking about how gdb can be used to debug legOS programs. I've hashed most of it out, but one thing has me stumped -- how can I do a software trap on a H8300? I'd like to hear any suggestions as to how I can get round this. The (...) (25 years ago, 17-Feb-00, to lugnet.robotics.rcx.legos)

| Hi all Is there any way to switch the IR LED on and leave it on. (as a kind of a headlight for the light sensor.)
