A .NET library to parse an Intel HEX file and emit a representative memory representation. This file format is used often for representing code when programming microprocessors and microcontrollers.
Link the following nuget package in your project in order to use the Intel HEX format reader: https://www.nuget.org/packages/IntelHexFormatReader/
Alternatively, install the package using the nuget package manager console:
Install-Package IntelHexFormatReader
Compatibility of the nuget package:
- .NET Standard 1.6
- .NET Framework 4.5
- .NET Framework 4.6
The following minimal snippet demonstrates loading an Intel HEX file and printing out it's resulting memory representation:
using IntelHexFormatReader;
namespace IntelHexFormatReaderDemo
{
internal class Program
{
private static void Main(string[] args)
{
HexFileReader reader = new HexFileReader(@"C:\\MyHexFiles\\myHexFile.hex", 32768);
MemoryBlock memoryRepresentation = reader.Parse();
foreach (MemoryCell cell in memoryRepresentation.Cells)
Console.WriteLine(cell);
}
}
}
This will resulting in output which might look like this:
MemoryCell : 00000000 Value: 0C (modified = True)
MemoryCell : 00000001 Value: 94 (modified = True)
MemoryCell : 00000002 Value: 72 (modified = True)
MemoryCell : 00000003 Value: 00 (modified = True)
MemoryCell : 00000004 Value: 0C (modified = True)
MemoryCell : 00000005 Value: 94 (modified = True)
MemoryCell : 00000006 Value: 9A (modified = True)
MemoryCell : 00000007 Value: 00 (modified = True)
MemoryCell : 00000008 Value: 0C (modified = True)
MemoryCell : 00000009 Value: 94 (modified = True)
MemoryCell : 0000000A Value: 9A (modified = True)
MemoryCell : 0000000B Value: 00 (modified = True)
MemoryCell : 0000000C Value: 0C (modified = True)
MemoryCell : 0000000D Value: 94 (modified = True)
MemoryCell : 0000000E Value: 9A (modified = True)
MemoryCell : 0000000F Value: 00 (modified = True)
...
Please note that HexFileReader
has a second constructor which allows you to pass any IEnumerable<string>
directly.
Alternatively, if you have only a single HEX record line to parse, you can use HexFileLineParser.ParseLine
directly:
string hexRecordLine = ":100130003F0156702B5E712B722B732146013421C7";
IntelHexRecord record = HexFileLineParser.ParseLine(hexRecordLine);
Console.WriteLine(record.ByteCount);
Console.WriteLine(record.Address.ToString("X4"));
Console.WriteLine(record.RecordType.ToString());
Console.WriteLine(record.Bytes[5]);
Console.WriteLine(record.Bytes[9]);
Console.WriteLine(record.CheckSum);
This will result in the following output:
16
0130
Data
94
43
199
The HexFileLineParser
does fairly exhaustive validation so you should not be able to construct invalid IntelHexRecord
objects.
