/**
* @brief ADC configuration
*
* Note that we do not configure all ADC channels,
* and not in the STM32L432KC order. Instead, we
* just define 5 ADC channels, for the Nucleo
* Arduino Nano header pins A0-A3 and A6 - all which are
* enabled by default and without collision with other
* features, for example, I2C or VCP_TX.
*
* 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 ADC1_IN10 is device 0,
* [Y] - describes used channel - indexed from 1,
* for example ADC1_IN10 is channel 10
*
* For Nucleo-L432KC this information is in board manual,
* Table 16 or STM32L432KC MCU datasheet - Table 14.
