    I need use 24-hour mode for digital clock. But i can’t change code properly.From datasheet  for DS1307 to select 24-hour mode i need set bit 6 to low. But nothing. How i can set bit 6 of timekeeper register to low or make other changes?

    It works without problems for PIC16F877A, but when i changed controller to PIC16F887 i get an error “Undeclared identifier CMON in expression”. Because PIC16F887 has no CMON register to turn off comparators. I inserted C1on.bit=0 and C2on_bit=0 to disable comparators for PIC16F887, but nothing. I still get not proper date/time on LCD. Do you have any idea?

    Yes, i mean that article. I changed microcontroller in the MikroC project, also i changed //CMCON = 0x07;   // To turn off comparators for PIC16F877

    and insert C1ON_bit = 0; C2ON_bit = 0;     // Disable comparators for PIC16F887 and ANSEL  = 0x04; ANSELH = 0;             // Configure AN pins as digital I/O for PIC16F887. But nothing. Could you have a look at my code
