ADC configuration

Note that we do not configure all ADC channels, and not in the STM32C071 order.

Instead, we just define 6 ADC channels, for the Nucleo Arduino header pins A0-A5.

The appropriate ADC device and channel for each pin can be found in the board manual in the pin assignment table. The format of the entries is ADC_IN[Y], where [Y] - describes the used channel - indexed from 1. For example: ADC_IN11 is Channel 11.

For the Nucleo-C071RB this information is in the board manual, Table 12 "ARDUINO connectors on NUCLEO-C071RB and NUCLEO-C092RC".

#define ADC_NUMOF   ARRAY_SIZE(adc_config)
 
static const adc_conf_t adc_config []
 

PWM configuration

The appropriate PWM device and channel for each pin can be found in the MCU datasheet table "Alternate function AF0 to AF7".

The format of the entries is TIM[X]_CH[Y], where TIM[X] is the timer device and [Y] describes the used channel (indexed from 0). For example TIM3_CH1 is Timer 3, Channel 1 which corresponds to Channel 0 in the PWM configuration structure. The port column in the table describes the connected port.

For the Nucleo-C071RB this information can be found in the MCU datasheet, Table 15 "Port B alternate function mapping (AF0 to AF7)".
