|
The tick interrupt is used to measure time. Therefore a higher tick frequency means time can
|
|
|
|
|
be measured to a higher resolution. However, a high tick frequency also means that the RTOS
|
|
|
|
|
kernel will use more CPU time so be less efficient. The RTOS demo applications all use a tick
|
|
|
|
|
rate of 1000Hz. This is used to test the RTOS kernel and is higher than would normally be
|
|
|
|
|
required.
|
|
|
|
|
More than one task can share the same priority. The RTOS scheduler will share processor time
|
|
|
|
|
between tasks of the same priority by switching between the tasks during each RTOS tick. A high
|
|
|
|
|
tick rate frequency will therefore also have the effect of reducing the 'time slice' given to
|
|
|
|
|
each task.
