SOLUTION
Helper macro to convert the ADC conversion
data from a resolution to another resolution.
Parameters:
__DATA__: ADC conversion data to be
converted
__ADC_RESOLUTION_CURRENT__:
Resolution of to the data to be converted 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
__ADC_RESOLUTION_TARGET__:
Resolution of the data after conversion 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:
ADC: conversion data to the requested
resolution
__LL_ADC_CALC_DATA_TO_VOL
TAGE
Description:
Helper macro to calculate the voltage (unit:
mVolt) corresponding to a ADC conversion data
(unit: digital value).
Parameters:
__VREFANALOG_VOLTAGE__: Analog
reference voltage (unit: mV)
__ADC_DATA__: ADC conversion data
(resolution 12 bits) (unit: digital value).
__ADC_RESOLUTION__: 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:
ADC: conversion data equivalent voltage value
(unit: mVolt)
Notes:
Analog reference voltage (Vref+) must be
known from user board environment or can be
calculated using ADC measurement.
__LL_ADC_CALC_TEMPERATUR
E_TYP_PARAMS
Description:
Helper macro to calculate the temperature (unit:
degree Celsius) from ADC conversion data of
