View the data stored at each flash address in an Intel-format hex file

intel-hex-viewer

Sometimes you have an Intel HEX file, but you want to view the contents as if it were raw sequential binary. This command-line utility does just that. It's basically hexdump for actual .hex files!

Usage

python view-hex.py my-hex-file.hex

Example Output

The output will always be a table where the left-most hex value is the memory address of the data which is printed in the right-most column. This is basically just a hexdump!

The other columns indicate the length of the data and the type of hex
