    A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

    The START condition will not be generated if FSMC clock is enabled.  See my other post: https://my.st.com/public/STe2ecommunities/mcu/mydiscussions.aspx.
