returns value '0'.
__LL_DAC_DIGITAL_SCALE
Description:
Helper macro to define the DAC
conversion data full-scale digital value
corresponding to the selected DAC
resolution.
Parameters:
__DAC_RESOLUTION__: This parameter
can be one of the following values:
LL_DAC_RESOLUTION_12B
LL_DAC_RESOLUTION_8B
Return value:
ADC: conversion data equivalent voltage
value (unit: mVolt)
Notes:
DAC conversion data full-scale
corresponds to voltage range determined
by analog voltage references Vref+ and
Vref- (refer to reference manual).
__LL_DAC_CALC_VOLTAGE_TO_
DATA
Description:
Helper macro to calculate the DAC
conversion data (unit: digital value)
corresponding to a voltage (unit: mVolt).
Parameters:
__VREFANALOG_VOLTAGE__: Analog
reference voltage (unit: mV)
__DAC_VOLTAGE__: Voltage to be
generated by DAC channel (unit: mVolt).
__DAC_RESOLUTION__: This parameter
can be one of the following values:
LL_DAC_RESOLUTION_12B
LL_DAC_RESOLUTION_8B
Return value:
DAC: conversion data (unit: digital value)
Notes:
This helper macro is intended to provide
input data in voltage rather than digital
value, to be used with LL DAC functions
such as
LL_DAC_ConvertData12RightAligned().
Analog reference voltage (Vref+) must be
either known from user board
environment or can be calculated using
ADC measurement and ADC helper
macro
