Quick start

You can install the intel_hex library using the OPAM package manager or any other method you prefer. If you are using Dune, please add the intel_hex library to your dependencies.

In use

The library provides a simple API for parsing and creating Intel HEX files. To create an Intel HEX file, you can use the following code:

Intel_hex.Record.
[
  Extended_linear_address 0x0F;
  Data (0x0000, "Hello ");
  Data (0x0007, "World!");
  End_of_file;
]
|> Intel_hex.Object.to_string
|> print_endline

:02000004000FEB
:0600000048656C6C6F20E6
:06000700576F726C6421CA
:00000001FF

And to parse a string containing an Intel HEX file:

":0600000048656C6C6F20E6\n:06000700576F726C6421CA"
|> Intel_hex.Object.of_string
(* - : Intel_hex.Object.t =
  [ Intel_hex.Record.Data (0, "Hello "); 
    Intel_hex.Record.Data (7, "World!") ] *)

However, the library also provides a module for working with memory images built from Intel HEX files or other sources.

Intel_hex.Memory.of_string ~block_size:6 "Hello World!"
(* - : Intel_hex.Memory.t =
 [ Intel_hex.Memory.Segment(0x0000, "Hello ");
   Intel_hex.Memory.Segment(0x0006, "World!") ] *)

For more details, see the API reference and the examples/ directory.
