Title: I need some servo help.
Post by: galannthegreat on February 12, 2009, 08:57:02 PM

I've got my servo panning back and forth, but it's not enough, I change for a longer delay and it doesn't change anything. What am I doing wrong?

Code: [Select]

#include "16f877a.h"
#use delay(clock=20000000)
#fuses HS


void main()
{

   setup_adc_ports(NO_ANALOGS);
   setup_adc(ADC_OFF);
   setup_psp(PSP_DISABLED);
   setup_spi(SPI_SS_DISABLED);
   setup_timer_0(RTCC_INTERNAL|RTCC_DIV_1);
   setup_timer_1(T1_DISABLED);
   setup_timer_2(T2_DISABLED,0,1);
   setup_comparator(NC_NC_NC_NC);
   setup_vref(FALSE);

   while(1)
   {
   output_high(PIN_D0);
   delay_us(500);
   output_low(PIN_D0);
   delay_ms(1000);
   output_high(PIN_D0);
   delay_us(1500);
   output_low(PIN_D0);
   delay_ms(1000);
   output_high(PIN_D0);
   delay_us(2500);
   output_low(PIN_D0);
   delay_ms(1000);
   output_high(PIN_D0);
   delay_us(1500);
   output_low(PIN_D0);
   delay_ms(1000);
   }
   
}
PS I am using a PIC 16F877a and I'm writing the code in CCS C.

and wow, I must not be having a good day because this topic is in the wrong category, sorry for any troubles.

If it doesn't rotate far enough it might be just the servo. How many degrees is it supposed to rotate?

Can you clarify exactly what it is actually doing, and what you want it to specifically do?
