Hi, The sys_time variable is the basic timekeeper for BrickOS. It is a 32-bit integer that is incremented every millisecond by the kernel. In older versions of the kernel you could access the variable directly, however, in 0.2.6.10 and later you (...) (22 years ago, 7-May-03, to lugnet.robotics.rcx.legos)

| | TIME STAMP for a LNP distributed robot

Hi, I'd like to make a basic implementation of a time stamp on a distributed schame, using Lamport's algorithm. It states basically that when a node receives a message, it get the time stamp that's contained on it, and compares with it's own, if the (...) (22 years ago, 7-May-03, to lugnet.robotics.rcx.legos)

(...) Dear Mark I will check the demo programs and more stuff. If i'm not wrong it looks to me that now we have 16K for the kernel ( c000-b000) = 4Kb more. If i got the results, i'm coming back to the forum. best regards Bernhard (22 years ago, 7-May-03, to lugnet.robotics.rcx.legos)

Oh note : you need to compile with -lfloat your kernel if you want to include it into kernel just add -lfloat to $LIBS in the Makefile.kernel nanobapt (22 years ago, 6-May-03, to lugnet.robotics.rcx.legos)

Hi Bernhard, Apparently the kernel is getting too big! By defining CONF_DSENSOR_MUX, enough extra code was generated to make the kernel exceed 12K. If you go to Makefile.user in the main BrickOS directory, change the following lines: # Base (...) (22 years ago, 6-May-03, to lugnet.robotics.rcx.legos)

Has anyone ever tried to upgrade the memory in the RCX? ( External RAM that is ). What about upgrade the CPU to 60kbyte PROM version? No need to use expanded mode, then a ton of I/O would be available... Anyone thought about building a RCX (...)
