  Subject: [ColdFire] sprintf x signed values 



  Hi people
  I´m working with 52235 and I´m trying to print a negative value for a char (int8) wich is -2, by using sprintf function, but the output is "254".  
  I did:
  {
  ...
  int8 sdata_8;

     sdata_8=-2;
     sprintf(lcd_controller.text_data_array,"%hi.", sdata_8);
  ...

  }
  I did the same experience using int16 and so I had success..
  Is there some special care to use sprintf with char?

  By the way, how can copy a negative value of a int8 to a int16?
  I tryied:
  sdata_16=sdata_8; and I got the calue 254 for sdata_16  ..and not -02 ...

  Thanks guys ...
