#define __LL_DAC_CALC_VOLTAGE_TO_DATA	(	__VREFANALOG_VOLTAGE__,
		__DAC_VOLTAGE__,
		__DAC_RESOLUTION__
	)

Value:

((__DAC_VOLTAGE__) * __LL_DAC_DIGITAL_SCALE(__DAC_RESOLUTION__)              \
   / (__VREFANALOG_VOLTAGE__)                                                  \
  )

Helper macro to calculate the DAC conversion data (unit: digital value) corresponding to a voltage (unit: mVolt).

Note:: 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 __LL_ADC_CALC_VREFANALOG_VOLTAGE().

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 values:

DAC	conversion data (unit: digital value)

#define __LL_DAC_CHANNEL_TO_DECIMAL_NB ( __CHANNEL__ ) ((__CHANNEL__) & DAC_SWTR_CHX_MASK)

Helper macro to get DAC channel number in decimal format from literals LL_DAC_CHANNEL_x.

Example: __LL_DAC_CHANNEL_TO_DECIMAL_NB(LL_DAC_CHANNEL_1) will return decimal number "1".

Note:: The input can be a value from functions where a channel number is returned.

Parameters:

__CHANNEL__

This parameter can be one of the following values:

Return values:

1...2

Helper macro to get DAC channel in literal format LL_DAC_CHANNEL_x from number in decimal format.

Example: __LL_DAC_DECIMAL_NB_TO_CHANNEL(1) will return a data equivalent to "LL_DAC_CHANNEL_1".

Note:: If the input parameter does not correspond to a DAC channel, this macro returns value '0'.

Parameters:

__DECIMAL_NB__ 1...2

Return values:
