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

UART configuration

#define UART_0_ISR   (isr_usart2)

#define UART_2_ISR   (isr_usart3)
 
#define UART_NUMOF   ARRAY_SIZE(uart_config)
