Though I can't provide any example code for uC/OS-II, I can recommend you to 
try without the timeout stuff at first and add support for that later. The 
timeout functionality isn't essential for just getting it working. If 
uC/OS-II supports semaphores, implementing the sys_arch shouldn't be too hard 
- at least not the semaphore functions.
