High priority repetitive task

Hi everyone,

My configuration:

  • nrf52832 microcontroller
  • Softdevice S132 V4.0.2
  • Nordic SDK 13.0

I need to develop a repetitive task with 10 Hz frequency. This task contains only algorithms and it doesn't involve the use of any peripherals.

This task has to be executed always and it must never be interrupted.

What is the best solution to do this? RTC, Timer, Timeslot, ...? Which mechanism give me the certainty of precise and uninterrupted task execution?
