ADC configuration.

Note that we do not configure all ADC channels, and not in the STM32F446 order. Instead, we just define 6 ADC channels, for the Nucleo Arduino header pins A0-A5.

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-F446ZE this information is in board manual, Table 18, page 56.
