Return value:
Value: "0" if the channel corresponds to a
parameter definition of a ADC external channel
(channel connected to a GPIO pin). Value "1" if
the channel corresponds to a parameter
definition of a ADC internal channel.
Notes:
The different literal definitions of ADC channels
are: ADC internal channel:
LL_ADC_CHANNEL_VREFINT,
LL_ADC_CHANNEL_TEMPSENSOR, ...ADC
external channel (channel connected to a GPIO
pin): LL_ADC_CHANNEL_1,
LL_ADC_CHANNEL_2, ... The channel
parameter must be a value defined from literal
definition of a ADC internal channel
(LL_ADC_CHANNEL_VREFINT,
LL_ADC_CHANNEL_TEMPSENSOR, ...), ADC
external channel (LL_ADC_CHANNEL_1,
LL_ADC_CHANNEL_2, ...), must not be a value
from functions where a channel number is
returned from ADC registers, because internal
and external channels share the same channel
number in ADC registers. The differentiation is
made only with parameters definitions of driver.
__LL_ADC_CHANNEL_INTERNAL
_TO_EXTERNAL
Description:
Helper macro to convert a channel defined from
parameter definition of a ADC internal channel
(LL_ADC_CHANNEL_VREFINT,
LL_ADC_CHANNEL_TEMPSENSOR, ...), to its
equivalent parameter definition of a ADC
external channel (LL_ADC_CHANNEL_1,
LL_ADC_CHANNEL_2, ...).
Parameters:
__CHANNEL__: This parameter can be one of
the following values:
LL_ADC_CHANNEL_0
LL_ADC_CHANNEL_1
LL_ADC_CHANNEL_2
LL_ADC_CHANNEL_3
LL_ADC_CHANNEL_4
LL_ADC_CHANNEL_5
