10.5.1 Preparing for RTOS

In addition to the preceding functions, the #use rtos() preprocessor command must be specified at the beginning of the program before calling any of the RTOS functions. The format of this preprocessor command is:

#use rtos (timer=n, minor_cycle=m)

where timer is between 0 and 4 and specifies the processor timer that will be used by the RTOS, and minor_cycle is the longest time any task will run. The number entered here must be followed by s, ms, us, or ns.

In addition, a statistics option can be specified after the minor_cycle option, in which case the compiler will keep track of the minimum and maximum processor times the task uses at each call and the task’s total time used.
