Hello: I need help to solve a problem of an exam. I have to make a program in assembly language keil4 and have problems with the RTC and the program in general, do not . The problem is the following: Setting the time and alarm activation in a real-time clock . The program should set a time in the RTC PCF8563 . If the character " #" reaches an alarm for the next minute be scheduled (when the latter are 00 ) . If the character comes " % " should set an alarm to within 20sg (regardless of the current minute and seconds). Thank you.
