Modifications to the original file

SPI access is needed only.
Using the macro XEE_ADDR for maintenance reasons (fast upgrade of EEPROM size).
Removed the XEEInit prototype. This function is not needed because the SPI bus is shared by LCD and EEPROM. Both devices work in different SPI modes. Therefore the initialization of SPI is done directly before an access to the EEPROM.
Added doxygen comments to the function prototypes.
Added the function XEEEraseEEPROM for erasing the complete EEPROM.
Added the function XEEWriteArray for writing data arrays into EEPROM. eWicht needs it for saving configuration settings.
Moved the function prototypes of XEEBeginWrite, XEEWrite, XEEEndWrite, XEEIsBusy to SPIEEPROM.c as static (private) functions of the EEPROM module.
Removed the functions XEEBeginRead, XEERead and XEEEndRead because no longer needed.

Functions

XEE_RESULT XEEReadArray (XEE_ADDR address, BYTE *buffer, BYTE length)

Reads desired number of bytes in sequential mode.

void XEEEraseEEPROM (void)

Erases the whole EEPROM.

void XEEWriteArray (WORD u16Address, BYTE *pu8Data, BYTE u8Len)

Writes an array of bytes to a specified address in the EEPROM.
