floating point variable error

[kdn]

I am trying to use floating point for calculation duty cycle for signal , but when i'm using try to use floating point it's giving error , I have attached picture of error.

According to the message you are getting I would assume you have created a project with the Stationery and you did not enable floating point support when creating the project.

I would recommend you to create a new project and to make sure you enable floating point support in the wizard. You should be able to link the application after that.

I hope it helps.

Thanks for replay , I am also using CAN module of MC9S12XHZ512 microcontroller I successfully archive transmitting of data from my microcontroller, but problem is that I am able to receive data only one time after that my controller get hang, I think that I have not clear my CAN receiver  interrupt flag, can you tell me where I can get CAN receiver interrupt flag in datasheet, I post my interrupt code for CAN below. Do MC9S12XHZ512 complier support sprintf function.

#pragma CODE_SEG __NEAR_SEG NON_BANKED

interrupt void Vcan1RxISR(void)

{

     unsigned char  RxBuffer[8],u8Length=8;

    unsigned int R,temp;

    LCD_Cmd(0x80);

     R = CAN1RXDSR0;

         Convert(R);

         LCD_Data(D);

         delay();

         LCD_Data(C);

         delay();

         LCD_Data(B);

         delay();;

         LCD_Data(A);

         delay();

      PORTA = 0xFF;

      CAN1RFLG_RXF = 1;

}

Receive Buffer Full Flag (RXF) is bit 0  in CANRFLG Register, please see table 14-11 in MC9S12XHZ512 data sheet:

http://cache.freescale.com/files/microcontrollers/doc/data_sheet/MC9S12XHZ512.pdf

HCS12 compiler supports sprintf function,but this function is very memory consuming. We don't recommend user use it frequently in the code.
