Handling errorsΒΆ

Many of the methods in IntelHex throw Python exceptions during error conditions. These can be caught and handled using try...except blocks like so:

>>> try:
...     mystring = ih.gets(0x20,20)
>>> except intelhex.NotEnoughDataError:
...     print "There is not enough data at that location"

See the API docs for information about errors raised by IntelHex. They are all subclasses of IntelHexError, so the except block above could be used to catch all of them. If your application has a way to gracefully handle these exceptions, they should be caught. Otherwise, Python will exit with a descriptive error message about the uncaught exception.

See Appendix A for error classes hierarchy.
