Hi, Does anyone know how to convert a large (20mb) HEX file into ASCII or another viewable format? What is the fastest method?
If by "Hex" you mean "Intel Hex", then it already is ASCII!
Intel Hex is an ASCII representation of binary data.
The format is described here: http://www.keil.com/support/docs/1584.htm There's also some examples - see if you recognise it!
