+/**
+ * @brief ADC configuration
+ *
+ * Note that we do not configure all ADC channels,
+ * and not in the STM32L412KB 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-L431KB this information is in board manual,
+ * Table 15 or STM32L412KB MCU datasheet - Table 14.
+ *
+ * VBAT is connected ADC1_IN18 internal line and a voltage divider
+ * is used, so that only 1/3 of the actual VBAT is measured. This
+ * allows for a supply voltage higher than the reference voltage.
+ *
+ * For STM32L412KB more information is provided in the MCU datasheet,
+ * in section 3.15.3 - Vbat battery voltage monitoring.
