ADC configuration
Note that we do not configure all ADC channels, and not in the STM32C031 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 ARD_A[N]_IN[X], where: [N] - describes analog pin number, [X] - describes used channel - indexed from 1, for example ARD_A5_IN16 is channel 16 For Nucleo-C031C6 this information is in board manual, Table 11, page 20. STM32C031C6 do not have internal channel for VBAT, more details provided in the MCU datasheet - section 3.14, page 20.

PWM configuration
To find appriopate device and channel find in the MCU datasheet table concerning "Alternate function AF0 to AF7" a text similar to TIM[X]_CH[Y], where: TIM[X] - is device, [Y] - describes used channel (indexed from 0), for example TIM2_CH1 is channel 0 in configuration structure (cc_chan - field), Port column in the table describes connected port. For Nucleo-c031c6 this information is in the MCU datasheet, Table 13, page 35.
