Initial value:

= {
    {GPIO_PIN(PORT_A, 0),  .dev = 0, .chan = 5},  
    {GPIO_PIN(PORT_A, 1),  .dev = 0, .chan = 6},  
    {GPIO_PIN(PORT_A, 3),  .dev = 0, .chan = 8},  
    {GPIO_PIN(PORT_A, 4),  .dev = 0, .chan = 9},  
    {GPIO_PIN(PORT_A, 7),  .dev = 0, .chan = 12}, 
}

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.
