Hi, the board is still under development, do far I dont have any PCB layout. All is done on a prototype board and not all comonents tested yet. A simple port of BrickOS is also not possible, because of the complete different structure of the µC. I (...)

GCC 3.3 has made multi-line string literals a syntax error. (They were deprecated from 3.0).

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)
