Thanks for your help.
I still have problem. I wrote a code to blink LED in RTC_1_EveryMinuteHandler() function but my GPIO pin stays always low. Shall I use any special configuration for RTC Interrupts or GPIO??
And which function in main creates RTC_1_INT.c file?? How main found it as its RTC Interrupts Routine?
I couldn't attach my file here you can find it in this link: https://ufile.io/bjgrv if you could take a look please, Thanks again.
