__LL_ADC_CALC_TEMPERATURE 发生硬件错误（HardFault）/ TS_CAL1 和 TS_CAL2 读取为零。在排查 ADC DMA 问题时，我用以下示例代码建了工程：
STM32Cube\Repository\STM32Cube_FW_L1_V1.10.3\Projects\NUCLEO-L152RE\Examples_LL\ADC\ADC_MultiChannelSingleConversion
然而，当它转换结果时，由于在 __LL_ADC_CALC_TEMPERATURE() 宏中发生除零错误，导致硬件故障。
/* Computation of ADC conversions raw data to physical values */
/* using LL ADC driver helper macro. */
uhADCxConvertedData_VoltageGPIO_mVolt = __LL_ADC_CALC_DATA_TO_VOLTAGE(VDDA_APPLI, aADCxConvertedData[0], LL_ADC_RESOLUTION_12B);
uhADCxConvertedData_VrefInt_mVolt = __LL_ADC_CALC_DATA_TO_VOLTAGE(VDDA_APPLI, aADCxConvertedData[1], LL_ADC_RESOLUTION_12B);
hADCxConvertedData_Temperature_DegreeCelsius = __LL_ADC_CALC_TEMPERATURE(VDDA_APPLI, aADCxConvertedData[2], LL_ADC_RESOLUTION_12B); // This crashes
仔细检查后发现，*TEMPSENSOR_CAL1_ADDR 和 *TEMPSENSOR_CAL2_ADDR 的读取结果为零。若使用调试器查看这些地址的内存内容，可以证实该情况。
作为参考，这两个定义位于 stm32l1xx_ll_adc.h 中，具体如下：
/* Temperature sensor */
#if defined (TEMPSENSOR_CAL1_ADDR_CMSIS)
#define TEMPSENSOR_CAL1_ADDR ((uint16_t*) TEMPSENSOR_CAL1_ADDR_CMSIS) /* Internal temperature sensor, address of parameter TS_CAL1: On STM32L1, temperature sensor ADC raw data acquired at temperature 30 DegC (tolerance: +-5 DegC), Vref+ = 3.0 V (tolerance: +-10 mV). */
#define TEMPSENSOR_CAL2_ADDR ((uint16_t*) TEMPSENSOR_CAL2_ADDR_CMSIS) /* Internal temperature sensor, address of parameter TS_CAL2: On STM32L1, temperature sensor ADC raw data acquired at temperature 110 DegC (tolerance: +-5 DegC), Vref+ = 3.0 V (tolerance: +-10 mV). */
#endif /* TEMPSENSOR_CAL1_ADDR_CMSIS */
