track time

[james]

I want to use a timer to track time. Like having a variable that shows minutes/seconds/ms/etc. But I don't know how to do with that.I want to use the rtc, but rtc1 had been used by app_timer and the rtc0 will be affected by Timer0,1,2.

I was trying a lot of solution how to do it but in result I decided to add external rtc component I'm using pcf8563 and for me this is the simplest solution.

thanks,finally I use another channel of RTC1 for the base of clock ticks.
