Macros

#define ADC_NUMOF   (9U)
 The nRF52 family of CPUs provides a fixed number of 9 ADC lines.
 
#define CLOCK_CORECLOCK   (64000000U)
 System core clock speed, fixed to 64MHz for all NRF52x CPUs.
 
#define UART_IRQN   (UARTE0_UART0_IRQn)
 Redefine some peripheral names to unify them between nRF51 and 52.
 
#define SPI_SCKSEL   (dev(bus)->PSEL.SCK)
 
#define SPI_MOSISEL   (dev(bus)->PSEL.MOSI)
 
#define SPI_MISOSEL   (dev(bus)->PSEL.MISO)
