 | | Lego RCX Emulator
|
|
Hello, In the last weeks I have started building a Lego RCX emulator. Unlike emulegOS it doesn't emulate the brickOS API, but instead it emulates the h8300 processor and the peripherals. This means that you can even use it to debug your kernel. The (...) (22 years ago, 4-Mar-03, to lugnet.robotics.rcx.legos)

A few months ago, I wrote a short program called "quartet" that would let a variable number of RCX bricks running LegOS play back a song in unison. I've made it available at (URL) . It should compile cleanly under Debian's legOS package. I don't (...) (22 years ago, 5-Mar-03, to lugnet.robotics.rcx.legos)

kernel_critsect_count is declared volatile in kernel/critsec.c, but without the volatile keyword in include/sys/critsec.h - this upsets gcc3. Please could these declarations be reconciled? Thanks, Max. (22 years ago, 15-Feb-03, to lugnet.robotics.rcx.legos)

Hi, I downloaded brickOS 0.2.6 and patched it to use the USB tower. All works well (firmdl3 is patched correctly, the module goes in, I can make my own .lx files), except for dll.
