BTW, make sure you include: #include <time.h> Otherwise, get_system_up_time() will only return 16 bits! Mark (21 years ago, 7-May-03, to lugnet.robotics.rcx.legos)

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 (...) (21 years ago, 7-May-03, to lugnet.robotics.rcx.legos)

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 (...) (21 years ago, 7-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.
