Hi,I'm trying to run 2 infinate loops at the same time. Is this possible? this is an example of what I'm trying to do. thanks #include <unistd.h> #include <dmotor.h> #include <dsensor.h> #include <conio.h> #include <time.h> pid_t fun_a; pid_t fun_c; (...)

(...) Not necessarily, that's why I'm asking. If the caller cleans up the stack, then the function just does an RTS and the caller adjusts the stack because it knows how much stuff was pushed on. For programs with lots of calls, this generates extra (...) (23 years ago, 19-Apr-01, to lugnet.robotics.rcx)

(...) Also: - caller cleans up parameters on stack - stack pointer is r7 The caller must clean up stack parameters b/c the return address is pushed after parameters are. -Kekoa (23 years ago, 18-Apr-01, to lugnet.robotics.rcx)

I believe that maybe the *ROM* calling convection is as Ralph described, but almost definitely the GCC calling convention is: - r0, r1, r2 hold parameters from left (...)

(...) DUDE! These are unbelievable......I would never even consider doing something like this due to other time constraints like partners and kids. These are amazing - a must see and candidate for Site of the Week, no? Cheers, Ralph Hempel (23 years ago, 18-Apr-01, to lugnet.robotics, lugnet.robotics.rcx)

All -- There's recently been some discussion in the Mindstorms Forums about the feasibility of producing an RCX-based Rubik's Cube solver. I am happy to report that I have finished a functional "late beta" version. You can see it at (URL) are (...) (23 years ago, 18-Apr-01, to lugnet.robotics, lugnet.robotics.rcx) !!

I'm trying to transfer some log-data from the RCX to the PC, using the "Serial.sendPacket(byte[] aBuffer, int aOffset, int aLen)", but it does not seem to work with a packet-length bigger than approx.. 24 bytes.

It's me again with some improvements for an "Electrical Data Link between 2 RCX". In the current version I changed the default condition of the link to "high" (in the transmitter: OFF(OUT_B)) so that the receiver has a 1 at its sensor input. So, you (...)
