# HG changeset patch # User Marco Filippi iz3gme.marco@gmail.com # Date 1334143076 -7200 # Node ID 72aaa91c7f1c6b0cdddfb1423eec4cead3fc211f # Parent d8f2d8194dc28af2f9a62ceb167a84decb047ce2 [RFC] Convert the FT-857/897 driver to use named struct definitions

This is an example usage of the previous patch which makes the definition of the FT-857/897 memory format significantly simpler. The diff doesn't do it justice, so look at the before and after files to see the difference.

#93
