Help... Needing a Kinetis Periodic Timer Example

[sam512bb]

Good day Mark,

I was curious if you can provide a Kinetis Periodic Timer Example?  Sadly, I cannot use uTaskerMonoTimer, as I require the task to run every 100 milliseconds.  I have tried doing this via TIMER_INTERRUPT_SETUP as well as PIT_SETUP, but with no success...

Thank you in advance!

Cheers,

Sam

Hi Sam

In ADC_Timers.h you can enable a PIT demo with TEST_PIT plus TEST_PIT_PERIODIC for a periodic interrupt.
Make sure that SUPPORT_PITS is enabled in app_hw_kinetis.h (so that the PIT driver is available).

This configures PIT0 using fnConfigurePIT() for a 500us interrupt period.

The interrupt handler (test_nmi()) will toggle an LED as defined by TOGGLE_TEST_OUTPUT so that a 500Hz square wave is generated. The output is, for example, the yellow LED on the K60 Tower board.

Regards

Mark
