5.1 Real Time Counter Driver Source Code Reference

This file contains the RTCounter APIs.

This file contains the methods needed to implement the RTCounter functionalities.

Notes:

  1. If you are interested in testing how this driver performs when the counter overflows we recommend you change this to 65500, which will make the counter start in range of the overflow, saving loads of time. Overflows are implemented as a rebase of absolute times so you may want to take time to understand this first.
  2. The ISR assumes the callback completes before the next timer tick. We only increment the overflow counter on every interrupt
