Make and run a library

Umm , I think it is not a serial monitor problem, It is the code itself.

To simplify the code I modified it to show only one calculation result, and now I get only zero and serial monitor displays
Julian Day: 0.00
Julian Day: 0.00
Julian Day: 0.00

And I can not solve this problem till now. Please help :slight_smile:

#include <spa.h>
spa_data spa;  
int result; 
float min, sec;

void setup()
{
  Serial.begin(9600);

}

void loop()
{

    spa.year          = 2003;
    spa.month         = 10;
    spa.day           = 17;
    spa.hour          = 12;
    spa.minute        = 30;
    spa.second        = 30;
    spa.timezone      = -7.0;
    spa.delta_t       = 67;
    spa.longitude     = -105.1786;
    spa.latitude      = 39.742476;
    spa.elevation     = 1830.14;
    spa.pressure      = 820;
    spa.temperature   = 11;
    spa.slope         = 30;
    spa.azm_rotation  = -10;
    spa.atmos_refract = 0.5667;
    spa.function      = SPA_ALL;

        
Serial.print ("Julian Day:     ");
Serial.println(spa.jd);
    
delay(10000);
}
