Hi, Does anyone know how to convert a large (20mb) HEX file into ASCII or another viewable format? What is the fastest method?
Using the HEX viewer?
A hex viewer is what you use when you want to look at a binary file.
If the file is already in hexadecimal format, it is already - as Andy notes - in a form of ASCII.
I don't recognize the binary data, and it doesn't looks to make sense if treated as IEEE floating-point data either.
"I don't recognize the binary data..."
I don't expect you would: I don't think it has anythihg to do with embedded firmware - the OP says he's a "data analysis consultant"
