UART configuration

#define UART_NUMOF   ARRAY_SIZE(uart_config)
 
#define UART_0_ISR   isr_uart0
 
static const uart_conf_t uart_config []
 

SPI configuration

#define SPI_NUMOF   ARRAY_SIZE(spi_config)
 
static const spi_conf_t spi_config []
 

I2C configuration

#define I2C_NUMOF   ARRAY_SIZE(i2c_config)
 
static const i2c_conf_t i2c_config []
 

ADC configuration

The ADC channels have a fixed mapping:

Channel MCU Pin Arduino pin on board
AIN0 P0.26 – (exposed, by no Arduino UNO pin)
AIN1 P0.27 – (exposed, by no Arduino UNO pin)
AIN2 P0.01 A0
AIN3 P0.02 A1
AIN4 P0.03 A2
AIN5 P0.04 A3
AIN6 P0.05 A4
AIN7 P0.06 A5

Expose those on Arduino pins A0 to A5

#define ADC_NUMOF   ARRAY_SIZE(adc_config)
 
static const adc_conf_t adc_config [] = {2, 3, 4, 5, 6, 7}
