Hi,

you&#39;ve to create you own OSTickISR().

you have to configure the timer to generate interrupts.

the timer interrupt handler has to launch OSTimeTick(), function which is given in uC/OS.

One another thing to be careful is when you make active timer interruption. It must be done after OSStart(), in the begining of the first task which is executing.
