sub: informasation about how to use hex file in java programming.
We are doing our projectwork on developing 8051 simulator using java
programing. During the work we need to open a intel hex file (.obj) and use
hex number for making decisions.
please give proper direction to overcome our problem.
===================#####====================
The intel hex file format is given below:
:05000000743E2494226F
:00000001FF
This is the format of an Intel hex file produced by a suitable
assembler. This code is often downloaded from a PC to a development system
and run from RAM. Alternatively, the hex file can be converted to a binary
file and programmed into an EPROM.
Now look at the top line...
* The first character (:) indicates the start of a record.
* The next two characters indicate the record length (hex number 10h in
this case).
* The next four characters give the load address (0080h in this case).
* The next two characters indicate the record type (see below).
* Then we have the actual data.
* The last two characters are a checksum (sum of all bytes + checksum =
00).
The last line of the file is special, and will always look like that above.
Record types:
* 00 - Data record
* 01 - End of file record
* 02 - Extended segment address record
* 03 - Start segment address record
* 04 - Extended linear address record
* 05 - Start linear address record
