__LL_ADC_CHANNEL_TO_DECIMAL_NB macro
Helper macro to get ADC channel number in decimal format from literals LL_ADC_CHANNEL_x. (1) On STM32F4, parameter available only on ADC instance: ADC1.\n (2) On devices STM32F42x and STM32F43x, limitation: this internal channel is shared between temperature sensor and Vbat, only 1 measurement path must be enabled.
Syntax
Arguments
__CHANNEL__
This parameter can be one of the following values: @arg LL_ADC_CHANNEL_0
@arg LL_ADC_CHANNEL_1
@arg LL_ADC_CHANNEL_2
@arg LL_ADC_CHANNEL_3
@arg LL_ADC_CHANNEL_4
@arg LL_ADC_CHANNEL_5
@arg LL_ADC_CHANNEL_6
@arg LL_ADC_CHANNEL_7
@arg LL_ADC_CHANNEL_8
@arg LL_ADC_CHANNEL_9
@arg LL_ADC_CHANNEL_10
@arg LL_ADC_CHANNEL_11
@arg LL_ADC_CHANNEL_12
@arg LL_ADC_CHANNEL_13
@arg LL_ADC_CHANNEL_14
@arg LL_ADC_CHANNEL_15
@arg LL_ADC_CHANNEL_16
@arg LL_ADC_CHANNEL_17
@arg LL_ADC_CHANNEL_18
@arg LL_ADC_CHANNEL_VREFINT

(1)(2) @arg LL_ADC_CHANNEL_VBAT
(1)
Return value
Value between Min_Data=0 and Max_Data=18
Notes
Example: __LL_ADC_CHANNEL_TO_DECIMAL_NB(LL_ADC_CHANNEL_4) will return decimal number "4". The input can be a value from functions where a channel number is returned, either defined with number or with bitfield (only one bit must be set).
