/** /**
* @name ADC configuration * @brief ADC configuration
* *
* We need to define the following fields: * Note that we do not configure all ADC channels,
* PIN, device (ADCx), channel * and not in the STM32F207ZG 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 ADC1_IN10 is device 0,
* [Y] - describes used channel - indexed from 1,
* for example ADC1_IN10 is channel 10
*
* For Nucleo-F207ZG this information is in board manual,
* Table 13, page 37.
