Here are two functions for a long delay with a variable parameter (16-bit).

long_delay_us():

Thank you for your help,PCM.
It now works.

My servo update in now at 70Hz ,I 'm not able to go lower than that(RTCC_DIV_256).It's slow, but it gets it's position right.


In case anyone finds it useful, hobby servo control code:

Code:

#include <16F876A.h>
#fuses HS,NOWDT,NOPROTECT,NOLVP
#use delay(clock=20000000)


void long_delay_ms(long count)
{
long k;

for(k = 0; k <count>0).
{
int16 sum;           
int16 b=20;
output_high(PIN_C0);
sum=400+(b*20);             //change value of b from 0 to 20(1ms to 2ms)
long_delay_ms(sum);        // 400 for 1ms,,600 for 1.5ms,800 for 2ms
output_low(PIN_C0); 
}



void main()
{
set_timer0(0);
setup_timer_0( RTCC_INTERNAL | RTCC_DIV_256 );
enable_interrupts(INT_TIMER0);
enable_interrupts(GLOBAL);
while(1);
}
