PIC 18f4550 and Hi-tech PRO compiler

Started by joolzg September 17, 2010
Right just started a little project using the 18f4550 for usb and wanted to save some data in the internal eeprom.

Easy or so i thought, as i am using Hi-tech PRO 18 V9.63 PL3 i thought i would use th eeprom_read and eeprom_write commands.

So to test i used MPLAB and put a message in the eeprom and checked my read routine, OK, and so as my checksum failed i tested the write 
routine and NOTHING

Now i have checked the config and i have 
_CONFIG( 1, USBPLL & IES0DIS & FCMDIS & HSPLL & CPUDIV1 & PLLDIV5);
_CONFIG( 2, VREGEN & PWRTDIS & BOREN & BORV20 & WDTDIS & WDTPS32K);
_CONFIG( 3, PBDIGITAL & LPTDIS & MCLREN);
_CONFIG( 4, XINSTDIS & STVREN & LPVDIS & ICPORTDIS & DEBUGDIS);
_CONFIG( 5, UNPROTECT) 
_CONFIG( 6, UNPROTECT) 
_CONFIG( 7, UNPROTECT) 

and if i check the config in MPLAB it says EEPROM_WRITE PROTECT is DISABLED

Anybody have any ideas?

Ive downloaded code from the web to do the eeprom_write code inline and still nothing.
