Hi all, I am trying to use internal temperature sensor on Nucleo L011K4 and using macro from LL library (__LL_ADC_CALC_TEMPERATURE_TYP_PARAMS) I get complete garbage. STM32Cube_FW_L0_V1.11.2STM32CubeMx 5.0.1LL libraries used, no HALADC is running in ...

Last update, with 3V calib reference in mind I get 14C at room temp (23C or so). Can do nothing more, need to recalibrate it.

With 3V reference it makes much more sense!For my L011 calibration is done for only one point, 130C. You solved this mystery, thanks a lot!

I got TS_CAL2 = 0x3A2. How to recalculate to mV required in macro? I am not sure that 3.3V reference was used for temperature sensor calibration.I tried converting to mV assuming 3.3V reference was used and I got -28C. So it still looks to me like m...

I think there is quite some time for startup, I have a long boot sequence.I understand that temperature sensor need long sampling time, I have 16Mhz ADC frequency and 16 divider, so with 12.5 clokcs for S&H it should be 12.5us sampling time.

Looks like you are right regarding TS_CAL2 unit. I will try that.Is TS_CAL values not writable?I have a background in characterization to calibrate temperature sensor.
