Thank for all! It's this! But I think the problems in the buttons! May It makes noise???? //Declare var unsigned temp1, temp_res,temp_set; unsigned short dvi, chuc; unsigned t; unsigned short hour, minute, sec; const unsigned short a[10] = {0x3F,0x06,0x5B,0x4F,0x66,0x6D,0x7D,0x07,0x7F,0x6F}; void in...

why No1 help me??? Please now!
Many Thanks!

Plz help me now! Tomorow i must complete this project!!!
I dont know why!!!!
Bored so much!

Hardware:
PIC16F877A
Crystal = 10MHz

LM35DZ -> AN0 ( PORTA.F0)
SWITCH -> AN1 (PORTA.F1)
UP Button -> AN2 (PORTA.F2)
DOWN Button -> AN3 (PORTA.F3)

8 LED7s -> PORTB
PORTD to controls LED7

I'm using PIC16F877a; crystal = 10MHz

I simulate in Proteus, Prog works OK!
if u need, i'll send 2u hardwave!

When I press a Button (which connects to PORTA.F2, PORTA.F3) then TIMER1 do not work. Plz help me to resolve that //Declare var unsigned temp1, temp_res,temp_set; unsigned short dvi, chuc; unsigned t; unsigned short hour, minute, sec; const unsigned short a[10] = {0x3F,0x06,0x5B,0x4F,0x66,0x6D,0x7D,...
