Function Documentation

void NRF_init

(

void

)

Initialize SPI interface and chip nRF24L01.

Definition at line 212 of file nrf24l01.c.

void NRF_prepareForReceive

(

)

After sending a byte you may set the device to RX mode.

Definition at line 324 of file nrf24l01.c.

bool_t NRF_receive

(

uint8_t *const

byte

)

Receive one byte from the air via chip nRF24L01.

Addresses are hardcoded:

See also:

RX_ADDRESS_P0 RX_ADDRESS_P1 TX_ADDRESS

Parameters:

byte

The data byte to receive.

Returns:

TRUE: if byte succesfully received. FALSE: if no input data.

Definition at line 340 of file nrf24l01.c.

void NRF_send

(

uint8_t

byte

)

Send one byte to the air via chip nRF24L01.

Addresses are hardcoded:

See also:

RX_ADDRESS_P0 RX_ADDRESS_P1 TX_ADDRESS

Parameters:

byte

The data byte to send.
