Macros

Clock configuration
Note
The radio will not work with the internal RC oscillator!
#define CLOCK_HFCLK
 
#define CLOCK_LFCLK
 
UART configuration
     The CPU only supports one UART device, so we keep it simple
#define UART_NUMOF   (1U)
 
#define UART_PIN_RX   17
 
#define UART_PIN_TX   18
 
Real time counter configuration
#define RTT_NUMOF   (1U)
 
#define RTT_DEV   (1) /* NRF_RTC1 */
 
#define RTT_MAX_VALUE   (0x00ffffff)
 
#define RTT_FREQUENCY   (1024)
 
ADC configuration

The configuration consists simply of a list of channels that should be used

#define ADC_CONFIG   {3, 4, 5, 6}
 
#define ADC_NUMOF   (4)
 
Radio device configuration

The radio is not guarded by a NUMOF define, as the radio is selected by its own module in the build system.

#define RADIO_IRQ_PRIO   1
 

Timer configuration

#define TIMER_0_ISR   isr_timer0
 
#define TIMER_NUMOF   (sizeof(timer_config) / sizeof(timer_config[0]))
 
static const timer_conf_t timer_config []
 

SPI configuration

#define SPI_NUMOF   (sizeof(spi_config) / sizeof(spi_config[0]))
 
static const spi_conf_t spi_config []
 

I2C (TWI) configuration

#define I2C_NUMOF   (sizeof(i2c_config) / sizeof(i2c_config[0]))
 
static const i2c_conf_t i2c_config []
