VCC与温度关系计算：
 VCC計算のインプリメント
/********** Nomalize Vcc data subroutine ******************************************/
//   (Normalized Vcc) = (ADC converted data ) x Constant_Vcc
//   Constant = 201.4 [uV/bit]
void normalize_adcvcc( void )

     nor_adc_vcc = ((unsigned long)((int)(adc_vcc)-(adc_offset))*20142)/100000;
}

温度計算のインプリメント
