RTC on STM32L053R8

Question asked by Nathapol Tanomsup on Mar 6, 2017

I tried to work with RTC (LSI) on STM32L0 but I got a problem. My desire is run a RTC like normal watch and get time at 2 point and find time between 2 point in milisecs but when I get time debugger always give me 0x00 even though using for loop to delay. I use AsynchPrediv = 127; and SynchPrediv = 255;
