internal temperature sensor.
Parameters:
__TEMPSENSOR_TYP_AVGSLOPE__:
Device datasheet data: Temperature sensor
slope typical value (unit: uV/DegCelsius). On
STM32F2, refer to device datasheet parameter
"Avg_Slope".
__TEMPSENSOR_TYP_CALX_V__: Device
datasheet data: Temperature sensor voltage
typical value (at temperature and Vref+ defined
in parameters below) (unit: mV). On STM32F2,
refer to device datasheet parameter "V25".
__TEMPSENSOR_CALX_TEMP__: Device
datasheet data: Temperature at which
temperature sensor voltage (see parameter
above) is corresponding (unit: mV)
__VREFANALOG_VOLTAGE__: Analog
voltage reference (Vref+) voltage (unit: mV)
__TEMPSENSOR_ADC_DATA__: ADC
conversion data of internal temperature sensor
(unit: digital value).
__ADC_RESOLUTION__: ADC resolution at
which internal temperature sensor voltage has
been measured. This parameter can be one of
the following values:
LL_ADC_RESOLUTION_12B
LL_ADC_RESOLUTION_10B
LL_ADC_RESOLUTION_8B
LL_ADC_RESOLUTION_6B
Return value:
Temperature: (unit: degree Celsius)
Notes:
Computation is using temperature sensor
typical values (refer to device datasheet).
Calculation formula: Temperature =
(TS_TYP_CALx_VOLT(uV) - TS_ADC_DATA *
Conversion_uV) / Avg_Slope + CALx_TEMP
with TS_ADC_DATA = temperature sensor raw
data measured by ADC (unit: digital value)
Avg_Slope = temperature sensor slope (unit:
uV/Degree Celsius) TS_TYP_CALx_VOLT =
temperature sensor digital value at temperature
CALx_TEMP (unit: mV) Caution: Calculation
relevancy under reserve the temperature
sensor of the current device has characteristics
in line with datasheet typical values. If
temperature sensor calibration values are
available on on this device (presence of macro
__LL_ADC_CALC_TEMPERATURE()),
temperature calculation will be more accurate
using helper macro
__LL_ADC_CALC_TEMPERATURE(). As
