HCS08-MC9S08GB32-Floating Points

[sada]

Dear Sir/Madam,

I am using Code worrior for 8 bit controller(MC9S08GB32),

I am new to the freescale controller.

I am facing a problen in using of floating points.

I included the IEEE32 bit while creating a Project.

But when i am debugging a program after ATD interrupt

          PTFDD = 0xFF;  //Battery 1 charging current;
          PTFD = PTFD&0xE3;
          ATD1SC=0x60; //ATD status Register,ATD interrupt is enabled,ATD0 selected;
         Delay200u();           
         chg1=((result*0.002442)+0.0125)*44.6;
         a[i]=chg1;
         sumchg1=sumchg1+a[i];

At the time of executing chg1 statement it hangs up in floting point routine.

Please help in this regard where is the mistake.

Hi sada,

Floating point calcs can take a long time.

Is it tripping the COP?

disable the COP as above and try again.

or remove the calculation and try again.
