* @name ADC configuration
*
* Note that we do not configure all ADC channels,
* and not in the STM32F439ZI order. Instead, we
* just define 6 ADC channels, for the Nucleo
* Arduino header pins A0-A5 and the internal VBAT channel.
*
* To find appropriate device and channel find in the
* board manual, table showing pin assignments and
* information about ADC - a text similar to ADC[X]_IN[Y],
* where:
* [X] - describes used device - indexed from 0,
* for example ADC12_IN10 is device 0 or device 1,
* [Y] - describes used channel - indexed from 1,
* for example ADC12_IN10 is channel 10
*
* For STM32F439ZI this information is in MCU datasheet,
* Table 10, page 53 or in Nucleo-f439ZI board manual,
* Table 17, page 52.
