Edit PIC microcontroller hex file directly. No need to rebuild the entire project.
Typical scenario: modify the hex file so that each microcontroller is programmed with unique information, for instance, username, password...
hex file Format for each line:
: CC AAAA TT D1 D2 D3 .... DN CS \r\n
CC - Data Count
AAAA - lower 16-bits of the address
TT - Data type
D1~DN - Data bytes
CS - Checksum = (~(CC+AA+AA+TT+D1+...+DN)) + 1
