When this code is running, after few countings program loses time calculation, restarts the calculation from the beginning. Maybe you will see a problem? Do i need to write results to eeprom? Sorry for dumb question - i am really beginner in programing pic uc.
| Code: | #include<16f628.h>
#fuses XT,NOWDT,NOPROTECT,NOLVP
#use delay (clock=20000000)
#include"lcd628.c"

XT fuses is for slower osc. (<10 mhz) use HS instead!
| Code: | meni:
if(!input(tarp) || !input(veikim)) meniu();
vykdymas();
delay_ms(100);
goto meni; |
uh you mean While ?
| Code: | While(1){
if(!input(tarp) || !input(veikim)) meniu();
vykdymas();
delay_ms(100);
} |
Best Regards,

| The thing is, that lcd shows only menu text, it stops to count time, sometimes seems like pic is being restarted. Can it be because of that fuse? Maybe i need to store data in eeprom or etc? |

Yes, this is possible. A PIC running at 20MHz needs HS fuse. For 4MHz or slower you use XT. |
