NRF52 and timing - actual state and what functions to use?
#nrf52-pca10040
Hi Martin, Nrf52832 has 3 RTC's. RTC0 is used for Bluetooth, RTC1 for system clock and RTC2 is usually available for application. You can use RTC2 with counter driver API (see counter.h). Then you can

Periodic k_timer's do not work in fractional ticks, no. If you schedule a 1000ms timeout it will be rounded up internally to exactly 33 hardware cycles, and that process will repeat each cycle. So you
