Hi
I am trying to make an alarm clock with a PIC16F690 and DS3231 RTC which displays on four SSDs. I am using the following link to do it since it is a similar configuration I am trying to use.
https://forum.allaboutcircuits.com/threads/i2c-pic16f690-and-rtc-ds3231-help.97156/
I used the same functions except I have added a display and delay function. I have tried changing the code many times but it still returns 0xFF. In the link, the individual mentions that the address was the problem but I have went through datasheets and found that the address to be used is 0x68 (which is used in the individuals code). I am programming in assembly language.
