Hi,

In STR71xLib (rtc.h) the 32 bit RTC counter is read with two consecutive 16 bit reads. Isn't there a risk that the counter changes between theese two reads?

Hi hinkenl,

In the STR71x device the RTC provides a set of continuously running counters driven by the 32 kHz external crystal.

By the way the RTC counter register can be read without any problem.

With regards,
