◆ checksum32()

uint32_t checksum32	(	const void *	data,

Creates a 32 bit checksum from data

Parameters

data	the data to create a checksum for
count	the number of bytes in data

Returns: the 32 bit checksum for data

Definition at line 531 of file data_sets.c.

◆ didToRmcBit()

uint64_t didToRmcBit	(	uint32_t	dataId,

Definition at line 563 of file data_sets.c.

◆ flashChecksum32()

uint32_t flashChecksum32	(	const void *	data,
		int	size
	)

Definition at line 557 of file data_sets.c.

◆ flipDouble()

void flipDouble ( void * ptr )

Flip the bytes of a double in place (8 bytes) - ptr is assumed to be at least 8 bytes Only flips each 4 byte pair, does not flip the individual bytes within the pair

Parameters

ptr	the double to flip

Definition at line 47 of file data_sets.c.

◆ flipDoubleCopy()

double flipDoubleCopy ( double val )

Flip the bytes of a double in place (8 bytes) Unlike flipDouble, this also flips the individual bytes in each 4 byte pair

Parameters

val	the double to flip

Returns: the flipped double

Definition at line 60 of file data_sets.c.

◆ flipDoubles()

void flipDoubles	(	uint8_t *	data,
		int	dataLength,
		int	offset,
		uint16_t *	offsets,
		uint16_t	offsetsLength
	)

Flip double (64 bit) floating point values in data

Parameters

data	the data to flip doubles in
dataLength	the number of bytes in data
offset	offset into data to start flipping at
offsets	a list of offsets of all doubles in data, starting at position 0
offsetsLength	the number of items in offsets

Definition at line 91 of file data_sets.c.

◆ flipEndianess32()

void flipEndianess32	(	uint8_t *	data,
		int	dataLength
	)

Flip the endianess of 32 bit values in data

Parameters

data	the data to flip 32 bit values in
dataLength	the number of bytes in data

Definition at line 73 of file data_sets.c.

◆ flipFloat()

void flipFloat ( uint8_t * ptr )

Flip the bytes of a float in place (4 bytes) - ptr is assumed to be at least 4 bytes

Parameters

ptr	the float to flip

Definition at line 19 of file data_sets.c.

◆ flipFloatCopy()

float flipFloatCopy ( float val )

Flip the bytes of a float (4 bytes) - ptr is assumed to be at least 4 bytes

Parameters

val	the float to flip

Returns: the flipped float

Definition at line 31 of file data_sets.c.

◆ flipStrings()

void flipStrings	(	uint8_t *	data,
		int	dataLength,
		int	offset,
		uint16_t *	offsets,
		uint16_t	offsetsLength
	)

Flip string values in data - this compensates for the fact that flipEndianess32 is called on all the data

Parameters

data	the data to flip string values in
dataLength	the number of bytes in data
offset	the offset into data to start flipping strings at
offsets	a list of offsets and byte lengths into data where strings start at
offsetsLength	the number of items in offsets, should be 2 times the string count

Definition at line 117 of file data_sets.c.

◆ getDoubleOffsets()

uint16_t* getDoubleOffsets	(	eDataIDs	dataId,
		uint16_t *	offsetsLength
	)

Get the offsets of double / int64 (64 bit) values given a data id

Parameters

dataId	the data id to get double offsets for
offsetsLength	receives the number of double offsets

Returns: a list of offets of doubles or 0 if none, offset will have high bit set if it is an int64 instead of a double

Definition at line 141 of file data_sets.c.

◆ getStringOffsetsLengths()

uint16_t* getStringOffsetsLengths	(	eDataIDs	dataId,
		uint16_t *	offsetsLength
	)

Gets the offsets and lengths of strings given a data id

Parameters

dataId	the data id to get string offsets and lengths for
offsetsLength	receives the number of items in the return value

Returns: a list of offsets and lengths of strings for the data id or 0 if none

◆ gpsToJulian()

double gpsToJulian	(	int32_t	gpsWeek,
		int32_t	gpsMilliseconds,
		int32_t	leapSeconds
