Any examples of direct read & write of nRF51822 registers?

[Doug_H]

Hi, are there any examples in C for how to directly access the registers on the chip? I realize this is a super basic question, but all the register access in the examples is wrapped in functions and macros that are not accessible, and I haven't found any code for this.

Specifically, I want to access the ADC and SPI registers directly with SD110 enabled. I'm using SDK v9.0.0

Thanks!

The registers are mapped to pointers to structures in nrf51.h

Be careful with SPI mapping. Use NRF_SPI0 or NRF_SPI1 NOT NRF_SPIM1

uint32_t spi_conf_reg;

spi_conf_reg = NRF_SPI0>CONFIG; 
RTT_PRINTF("SPI0 REG: %x\n", spi_conf_reg);
