On the STM32G071RB board, I tried to read the temperature using HAL-based conversion macros. At ambient temperature I get reading of 47 to 60 celsius depending on whether or not the HAL_ADCEx_Calibration_Start() is called to improve accuracy.The macr...

Ah, ok , thank you for the answer.So I neglected that my CPU is running in loop 100% of the time. My fault.Thanks a lot for pinpoint this.Then I consider closed this question.ByeLuca Pizzini

have someone else tried such measurement? With which results?

I did expect something around 25 celsius because that is the ambient temperature. So 47 are too much.I do not know how much is the internal temperature. Do you think it could be 47 degrees? I don't.The sampling time I think is correct.The VDD convers...

One last info, I tried on the NUCLEO board (micro STM32G071RBT6) and on a custom board (micro STM32G030K6) with the same results so the calibrations stored by ST I think are correct. I suppose the trouble must be in the firmware.ByeLuca Pizzini

At first thanks for your quick answer.Yes, I enabled all what I need, read the righ channel and adjust the VDD reading.The following code is to configure the temperature channel:sConfig.Channel = ADC_CHANNEL_TEMPSENSOR;sConfig.SamplingTime = ADC_SAMP...
