Function Documentation

int bfb_assemble_data	(	bfb_data_t **	data,
		int *	size,
		int *	len,
		bfb_frame_t *	frame
	)

Append BFB frame to a data buffer.

int bfb_check_data	(	bfb_data_t *	data,
		int	len
	)

Check if data buffer is complete and valid.

uint8_t bfb_checksum	(	uint8_t *	data,
		int	len
	)

Returns the whole buffer folded with xor.

bfb_frame_t* bfb_read_packets	(	uint8_t *	buffer,
		int *	length
	)

Retrieve actual packets.

int bfb_send_data	(	fd_t	fd,
		uint8_t	type,
		uint8_t *	data,
		uint16_t	length,
		uint8_t	seq
	)

Stuff data into packet buffers and send all packets.

int bfb_stuff_data	(	uint8_t *	buffer,
		uint8_t	type,
		uint8_t *	data,
		uint16_t	len,
		uint8_t	seq
	)

Stuff data frame into serial cable encapsulation.

buffer needs to be of at leaset len+7 size Type 0x01: "prepare" command. Type 0x02: first transmission in a row. Type 0x03: continued transmission. seq needs to be incremented afterwards.

int bfb_write_packets	(	fd_t	fd,
		uint8_t	type,
		uint8_t *	buffer,
		int	length
	)

Send actual packets.

Patch from Jorge Ventura to handle EAGAIN from write.

		uint8_t	type,
		uint8_t	subtype
	)

Send a cmd, subcmd packet, add chk (no parameters).

int bfb_write_subcmd0	(	fd_t	fd,
		uint8_t	type,
		uint8_t	subtype
	)

Send a cmd, subcmd packet.

int bfb_write_subcmd1	(	fd_t	fd,
		uint8_t	type,
		uint8_t	subtype,
		uint16_t	p1
	)

		uint8_t	subtype,
		uint32_t	p1,
		uint16_t	p2
	)

Send a cmd, subcmd packet, add long, word parameter.
