ADC configuration

Note that we do not configure all ADC channels, and not in the STM32F334 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 []
 

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)
 
static const dma_conf_t dma_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)
