从手册上看的是：
/* Temperature sensor calibration value address */
#define TEMP110_CAL_ADDR ((uint16_t*) ((uint32_t) 0x1FFFF7C2))
#define TEMP30_CAL_ADDR ((uint16_t*) ((uint32_t) 0x1FFFF7B8))
#define VDD_CALIB ((uint16_t) (330))
#define VDD_APPLI ((uint16_t) (300))
int32_t temperature; /* will contain the temperature in degree Celsius */
temperature = (((int32_t) ADC1->DR * VDD_APPLI / VDD_CALIB)
- (int32_t) *TEMP30_CAL_ADDR );
temperature = temperature * (int32_t)(110 - 30);
temperature = temperature / (int32_t)(*TEMP110_CAL_ADDR
- *TEMP30_CAL_ADDR);
temperature = temperature + 30;

用这个测出来是70多度
在网上搜的是图片上那样测出来是40多度，到底哪个可以用啊？
