===Using the IRQ for Preemptive Multitasking===
The timer IRQ can also be used to perform preemptive multitasking. To give the currently running task some time to run, set a threshold, for example of 3 ticks. Use a global variable like the one before but go up from 0, and when that variable hits 3, switch tasks. How you do so is up to you.
