ADS1298 sample rate strange issue ;

Other Parts Discussed in Thread: ADS1298

Hi All

I have a strange problem here in ADS1298 ; please guide me to know what is going on .

I am using the ,nternal master clock .

I set sampling rate with high resolution mode to 8ksps; but I get 16ksps!

I can set CONFIG 1 to 0x82 ; I read back with ID it is all ok .

I set a counter in the interrupt to counter DRY pulses I get 16000 pulse !

 void EXTI0_IRQHandler(void)
{
static unsigned int i,k=0;

  if(EXTI_GetITStatus(EXTI_Line0) != RESET)
  {
    i++;
  if(i==16000)/// to toggel the led for 1 second !
  {

   
   
  i=0;
  toggle_led_1();
  }
  

/* Clear the EXTI line 0 pending bit */
    EXTI_ClearITPendingBit(EXTI_Line0);
  }
 
 }

Thank you in advanced

Hector
