ADC configuration

Note that we do not configure all ADC channels, and not in the STM32F302 order.

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

#define VBAT_ADC   ADC_LINE(6)
 VBAT ADC line.
 
#define ADC_NUMOF   ARRAY_SIZE(adc_config)
 
static const adc_conf_t adc_config []
 

UART configuration

#define UART_0_ISR   (isr_usart2)
 
#define UART_1_ISR   (isr_usart1)
 
#define UART_2_ISR   (isr_usart3)
 
#define UART_NUMOF   ARRAY_SIZE(uart_config)

PWM configuration

#define PWM_NUMOF   ARRAY_SIZE(pwm_config)

SPI configuration

#define SPI_NUMOF   ARRAY_SIZE(spi_config)

I2C configuration
