hi everybody.. all these terms have really got me tangled up. what i want to create is a downloader that downloads hex files of compiled ccs codes like (ex_swt.c) into the pic.. the pic on my development board has already has its firmware programmed before. so that is not what i want. what i want to create is a downloader or whatever its called..

eblc1388 said:Your binary data are(in hex): 0x3000, 0x008A, 0x289A, 0x0000, 0x3023,.... with the checksum 0xFF at the end. These are placed into each address location of the PIC flash memory. Notices that because every word is 14-bit wide, the two MSDs would have to be in the range 0x00~0x3F.
To understand how one can handle these data and actually send them into the PIC, you need to get hold of the Microchip programming Spec document 39589b. It is for 16F87XA. I searched but there is no such document for 16F87X. Read it until you understand its content.
