Detailed Description

Read .hex file in "Intel HEX" format.

Note

that OSTC3 firmware is NOT distributed in Intel HEX format, but is first flatened, then encrypted, then written back in a similar looking format.

Constructor & Destructor Documentation

HexFile::HexFile

(

)

Create an empty object.

HexFile::~HexFile

(

)

Member Function Documentation

bool HexFile::allocate	(	size_t	memSize,
		unsigned char	fill = 0xFF
	)

Allocate initialized space.

unsigned int HexFile::checksum

(

)

const

Returns the 4 bytes checksum of the loaded data.

This is a simple Adler32 checksum: The lower 16bits are the sum of all the bytes (modulo 65536). And the second 16bits are the sum of the running sum itself (also modulo 65536).

const unsigned char * HexFile::data

(

)

const

Return a pointer to the loaded data.

void HexFile::load

(

const QString &

fileName

)

Load the .hex file into the internal buffer.

Returns

TRUE is ok, FAlSE if some error occurs.

void HexFile::loadEncrypted	(	const QString &	fileName,
		unsigned char	secretKey[16]
	)

Reload encrypted HEX file.

void HexFile::saveEncrypted	(	const QString &	fileName,
		unsigned char	secretKey[16]
	)

Save to encrypted HEX file.

bool HexFile::sqwiz

(

size_t

newMemSize

)
