• boards

  Unless otherwise specified, this example runs on the SliceKIT Core Board, but can easily be run on any XMOS device by using a different XN file.

Timers can be used to pause a task until a certain amount of time has passed. First input the current time from the timer:

t :> start_time;

Next compute the time you want the task to wait until, by adding the desired number of timer ticks to the start time:

end_time = start_time + 123;

Finally use the following statement to wait for end_time to be reached:

t when timerafter(end_time) :> void;
