Orient both RCXs so that they are pointing towards the ceiling. Set the RCX transmit power level to high (default is probably low power); there's probably some Lejos function to do this -- all it requires is setting one bit in an I/O register to 1. (...)

(...) Hi Steve, Thanks, you were right about the compiler being ok. I changed "pid_t" to "tid_t" and got the thread statements working correctly. Finally, by consulting BrickOS documentation I found out the new syntax for the old "sys_time" command (...) (19 years ago, 4-Aug-05, to lugnet.robotics.rcx.legos)

Greetings helpful companions. Now that I've buttered you up, let's move on... I've built a robotic arm using my RCX 1.0 brick. I'm controlling it via my computer with LeJOS (not important, I think). What my issue arises is if my arm rotates, the IR (...) (19 years ago, 4-Aug-05, to lugnet.robotics.rcx)

(...) I don't think it's a problem with the compiler. There have been changes to the BrickOS code over the years. I know the value sys_time has been replaced with the function Get_sys_up_time().
