Problem with Output Pins PORTB

[Nihel01]

Hi, i'am new to PIC and i'am trying to do a very simple project to flash 8 LEDs in PORTB in sequence with the following code, on a PIC16F887:

void main(){


PORTB = 0;
TRISB = 0;
ANSELH = 0;
ANSEL = 0;

do {

PORTB = 128;
Delay_ms(500);
PORTB = 64;
Delay_ms(500);
PORTB = 32;
Delay_ms(500);
PORTB = 16;
Delay_ms(500);
PORTB = 8;
Delay_ms(500);
PORTB = 4;
Delay_ms(500);
PORTB = 2;
Delay_ms(500);
PORTB = 1;
Delay_ms(500);

}

while(1);

}


But only the LEDs on RB7,6 and 5 are working the others are not. In MikroC,In the Edit Project window, I used de Dafault settings, LVP OFF, HS Enabled and WDT disable. I tried other ports and the problem persists, with only 3 LEDs flashing. One thing I noticed is that when I open the .hex file on WinPIC800 and go to the CONFIG tab the LVP is On.

Help would really be appreciated cause i've tried everything and can't find why is this not working

Hello,

I have tested your code and it works just fine.
Please notice that if the low voltage programming is ON, you could experience this behavior.

Please try to disable it manually and program your controller again.

Best regards.
