ADC configuration

Note that we do not configure all ADC channels, and not in the STM32F303 order.

Instead, we just define 6 ADC channels, for the Nucleo Arduino header pins A0-A3 and A6

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

DMA streams configuration

#define DMA_0_ISR   isr_dma1_channel2
 
#define DMA_1_ISR   isr_dma1_channel3
 
#define DMA_2_ISR   isr_dma1_channel4
 
#define DMA_3_ISR   isr_dma1_channel7
 
#define DMA_NUMOF   ARRAY_SIZE(dma_config)

UART configuration

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