#define CSN_LOW ( ) do {RFCSN = 0U; } while(false)

Macro that set radio's CSN line LOW.

Definition at line 32 of file hal_nrf_hw.h.

#define CSN_HIGH ( ) do {RFCSN = 1U; } while(false)

Macro that set radio's CSN line HIGH.

Definition at line 37 of file hal_nrf_hw.h.

#define CE_LOW ( ) do {RFCE = 0U;} while(false)

Macro that set radio's CE line LOW.

Definition at line 42 of file hal_nrf_hw.h.

#define CE_HIGH ( ) do {RFCE = 1U;} while(false)

Macro that set radio's CE line HIGH.

Definition at line 47 of file hal_nrf_hw.h.

#define HAL_NRF_HW_SPI_WRITE ( d ) do{SPIRDAT = (d);} while(false)

Macro for writing the radio SPI data register.

Definition at line 52 of file hal_nrf_hw.h.

#define HAL_NRF_HW_SPI_READ ( ) SPIRDAT

Macro for reading the radio SPI data register.

Definition at line 57 of file hal_nrf_hw.h.

#define HAL_NRF_HW_SPI_BUSY (!(SPIRSTAT & 0x02U))

Macro specifyng the radio SPI busy flag.

Definition at line 62 of file hal_nrf_hw.h.

#define CE_PULSE ( )

Value:

do { \
  uint8_t count; \
  count = 20U; \
  CE_HIGH();  \
    while(count--) {} \
  CE_LOW();  \
  } while(false)

Pulses the CE to nRF24L01p for at least 10 us
