c - I can't show time from DS1307 with PIC16f88 -
i write program long code alarm clock. use ccs compile use rom =80% ram=8%-51% . simulate program in proteus work. when use in real hardware show time = 00:00:80 , not run second. code read time ds1307. change battery 3v of ds1307 show same time. when push button not show too. think if code wrong should can't run in proteus. how fix ? please me.
this code.

you must use device (ds1307) 32.768khz quartz crystal instead 20mhz crystal. , don't forget use right capacitances. see datasheet of device page 7.
