I can't measure tempsensor with vbat and vref because cubemx generates low layer code in the following order:
LL_ADC_REG_SetSequencerRanks(ADC1, LL_ADC_REG_RANK_6, LL_ADC_CHANNEL_TEMPSENSOR);
LL_ADC_SetChannelSamplingTime(ADC1, LL_ADC_CHANNEL_TEMPSENSOR, LL_ADC_SAMPLINGTIME_640CYCLES_5);
LL_ADC_SetChannelSingleDiff(ADC1, LL_ADC_CHANNEL_TEMPSENSOR, LL_ADC_SINGLE_ENDED);
LL_ADC_SetCommonPathInternalCh(__LL_ADC_COMMON_INSTANCE(ADC1), LL_ADC_PATH_INTERNAL_TEMPSENSOR);
/** Configure Regular Channel
*/
LL_ADC_REG_SetSequencerRanks(ADC1, LL_ADC_REG_RANK_7, LL_ADC_CHANNEL_VREFINT);
LL_ADC_SetChannelSamplingTime(ADC1, LL_ADC_CHANNEL_VREFINT, LL_ADC_SAMPLINGTIME_640CYCLES_5);
LL_ADC_SetChannelSingleDiff(ADC1, LL_ADC_CHANNEL_VREFINT, LL_ADC_SINGLE_ENDED);
LL_ADC_SetCommonPathInternalCh(__LL_ADC_COMMON_INSTANCE(ADC1), LL_ADC_PATH_INTERNAL_VREFINT); // Previously enabled tempsensor bit get overwritten here and only internal vrefint channel is enabled.. I took a few hours until I figured out why ny MCU temp measuring module isn't works since I ported my ADC to HAL from LL
Finaly result is only vrefint is enabled and tempsensor is disabled. CubeMX should use logical OR in this case. In HAL it is implemented correctly, but this implementation missing from LL.
Solution is:
LL_ADC_SetCommonPathInternalCh(__LL_ADC_COMMON_INSTANCE(ADC1), LL_ADC_PATH_INTERNAL_TEMPSENSOR | LL_ADC_PATH_INTERNAL_VREFINT);
