I am trying to migrate from PIC16F886 to PIC18F24K40 . NOw here I am trying to communicate PIC18F24K40 with DS1307 and Display it on 4 Segment Display. I have tested my code on PIC16F886 but not worked on PIC18F24K40 . SInce PIC18F24K40 uses MPLAB X ide and creates MCC code configuration based I2c c file and .h file . Can someone suggest what wrong done i have done in below code
I could not able to update time once written.
