JVIntelHEX

A javascript Intel HEX format writer (lightweight implementation)

Version 1.0 Created by Julian Vidal

What does it do?

Takes some arbitrary data and wraps it in the Intel HEX protocol. Note that this is not a full implementation and all the record types are not defined. It is up to you to fork this and implement them if you ever need them.

Installation

You only need to copy jvintelhex.js to your project.

Usage

// The data needs to be an array of bytes, so values over 255 won't work in this implementation.
data = new Array(4, 5);

// How many bytes per HEX record. Usually 16 or 32 but can take arbitrary numbers.
byteCount = 16;

// Your record's start address (you might not even need this so 0 is a good option if you don't know what this is)
startAddress = 0;

// Wether to prepend all records with ':' like in the official Intel HEX specs. 
useRecordHeader = true;

intelHEX = new JVIntelHEX(data, byteCount, startAddress, useRecordHeader);

// Crunch the data
intelHEX.createRecords();

console.debug('HEX file', intelHEX.getHEXFile());
console.debug('HEX as byte array', intelHEX.getHEXAsByteArray());
console.debug('HEX as binary string', intelHEX.getHEXAsBinaryString());

Examples

You will find a fully working example in the examples directory.
