help nmn po mga sir... program po nmen yan s tower pro servo z8f082a, 28 pins.. the problem is ayaw po nia tumigil.. continuous nmn po siya,, ano po kya ang mali sa program or dapat namen idagdag para tumigil??/
maraming salamat po sa lahat..
GodbLess..

mukhag dun sa "isr_timer0" interrupt routine ang problema.
kelangan pa atang i-clear yung interrupt request after ma-service yung interrupt.

[daxz]

sir yus.. wat do you mean po... pano po icclear ung interrupt?
newbie po kc ko dito sa z8..

['yus]

... pano po icclear ung interrupt?
...

example:

Code:

//....
#pragma interrupt
void isr_timer0(void)
{
     ctr++;
     IRQ0 &= ~0x20;  // clear Timer 0 Interrupt Request bit
}
//....

[daxz]

sir yus... ganon pa rin po.. wala pa rin pong pagbabago.. sana matulungan nio po kme...

'bat dun sa "main()" mo halos magkapareho lang yung ini-execute ng dalang "if" condidtion:

Code:

void main(void)
   {
.....
   while(1)
      {
      if(U0RXD=='3')
         {
         PBOUT |= 0x01; // clockwise
         delay_ms(1);
         PBOUT &= 0xFE;
         delay_ms(19);
         }

      if(U0RXD=='4')
         {
         PBOUT |= 0x01; // countercw
         delay_ms(2);
         PBOUT &= 0xFE;
         delay_ms(18);
         
         }
      }
}

yung timer0 and timer1, saan mo ginagamit? sa "delay" function lang ba?
kung sa "delay" lang, (temporarily) 'wag ka munang gumamit ng timer (and timer interrupt),
para madaling ma-debug ang code.
gamit ka muna ng simple "counter".

[daxz]

meaning po hindi n ko gagamit ng timer? mpapatakbo p rin b ang servo khit alang timer?

['yus]

.... mpapatakbo p rin b ang servo khit alang timer?

pwede kahit walang timer.

[daxz]

pano po gagawin??? magdedeclare lang po b kmi ng ctr??

[daxz]

sir yus sana po matulungan nio kmi... defens n po kc nmin sa monday.. maraming salamat po talaga...
