Hello,
SigmaStudio includes the E2Prom Read/Write Window shown below. It appears from posts such as http://ez.analog.com/message/19512#19512, however, that it hasn't worked recently. When I tried it today, I could not get it to save anything to a file.
Even if you could access the E2Prom contents (perhaps using another utility), it wouldn't help much because no decompiler is available to translate the object code back into a project file -- see http://ez.analog.com/message/19512#19512. In addition to the issue of software security, a decompiler won't work very well anyhow. Shown below is a snippet of a huge project that nearly fills up a ADAU1701. As a project it uses 200K of disc space, but compiles down to fit into a 8K E2Prom. As a result, a decompiler would not reconstruct the original project. As a minimum, the use of aliases with recognizable labels would be lost.
Actually I did lose this project at one point in its development. Surprisingly, it only took about a day to re-enter it from scratch, and in the process I turned it from a scatter-wired mess into something far neater and more maintainable -- see http://ez.analog.com/message/63999#639994
Thus I found a silver lining in this misfortune. It also taught me to save multiple copies of each project revision.
Best regards,
Bob
