Function Documentation

◆ rfcore_peek_rx_fifo()

uint_fast8_t rfcore_peek_rx_fifo ( int idx )

Peek a single byte from the RX FIFO.

Peeking, as opposed to reading, a byte from the RX FIFO will not advance the FIFO pointer. Further, bytes may be read from any position in the FIFO by providing an index.

Parameters

[in] idx The index of the byte to peek

Returns: The byte at index idx

◆ rfcore_poke_tx_fifo()

void rfcore_poke_tx_fifo	(	int	idx,
		uint_fast8_t	byte
	)

Poke a single byte in the TX FIFO.

Poking, as opposed to writing, a byte to the TX FIFO will not advance the FIFO pointer. Further, bytes may be written to any position in the FIFO by providing an index.

Parameters

[in]	idx	The index of the byte to write to
[in]	byte	The byte to write

◆ rfcore_read_byte()

uint_fast8_t rfcore_read_byte ( void )

Read a single byte from the RX FIFO.

This function will return the first currently unread byte from the RX FIFO, and advance the FIFO pointer by one. Hence, subsequent calls to this function will return subsequent bytes from the RX FIFO.

Returns: The first currently unread byte from the RX FIFO

◆ rfcore_read_fifo()

void rfcore_read_fifo	(	void *	buf,
		uint_fast8_t	len
	)

Read the remaining unread data from the RX FIFO.

Parameters

[out]	buf	The buffer to read the data into
[in]	len	The maximum length of the buffer

◆ rfcore_strobe()

void rfcore_strobe ( uint_fast8_t instr )

Issue a command strobe from the CPU to the radio.

Parameters

[in] instr The instruction to issue

◆ rfcore_write_byte()

void rfcore_write_byte ( uint_fast8_t byte )

Write a single byte to the next index of the TX FIFO.

Parameters

[in] byte The byte to write

◆ rfcore_write_fifo()

void rfcore_write_fifo	(	const void *	buf,
		uint_fast8_t	len
	)

Write a string of bytes to the TX FIFO.

Parameters

[in]	buf	The buffer containing the data to write
[in]	len	The length of the data to write
