pic16f877a problem output

[jackobian]

I have pic16f877a, i use mikroc program for code implementation. and xeltek 5000e as a programmer. when i write value such as

main()
{
trisb=0;//port b out out
while(1)

{
portb=0x00001111;
}
}

and measure the value with oscilloscope it always below 0.5v. please help me

My First question is that did your program compile very well?

Main(){
             TRISB =  0x00;
        While(1){
    PORTB = 0B00001111;
     }
}

Secondly did you simulate your project on softwares like Proteus before designing it in real world?.

Should work. Possible schematic or configuration error.

Maybe is missing the famous MCLR 10K pullup resistor!!!
Or oscillator is wrong into the configuration of miKroc (use Ctrl + Shift + E, to see the parameters).

void main()
{
  TRISB = 0x00;
  TRISC = 0x00;
  PORTB = 0B00001111;
  PORTC = 0B11110000;
  while(1)
  {
  }
}

I attach my example using 8MHz crystal...

check your oscillator. I think the oscillator has problem.
