I just got new batteries for my RCX, so I just did an actual test. I didn't get very far. I don't believe that it is registering the touch sensors.

It probably should. But why does it say that "pid1" is undeclared? Shouldn't that be taken care of in tm.h or unistd.h? (24 years ago, 13-Mar-01, to lugnet.robotics.rcx.legos)

| | Kernel proposal - message passing and signals

I worked on that. I'm having trouble with "execi()" and some stuff related to it.

(...) No, it will not. Functions don't work like that, in general. If you want to call a function and have it run independently of the calling function, you must use execi() to start it. (24 years ago, 12-Mar-01, to lugnet.robotics.rcx.legos)

(...) The limit is in the checksum routine built into the RCX - it only does a sum up to 0xCC00! So you may need to fiddle with firmdl to allow a larger SREC image, but only checksum up to 0xcc00. Hope this helps. Ralph Hempel (24 years ago, 9-Mar-01, to lugnet.robotics.rcx.legos)

Hi! I'm using legOS 0.2.4 on Cygwin, and since memory is tight, I thought I'd try statically compiling my program to an .srec file, and using firmdl3 to download it, since I can do without the keys,conio,task, and memory managment stuff.
