Move from UNO to mega 2600

-

hi all,
i have moved boards mega uno. have transferred numbered pins project on identical pins on mega uno , when compile acceleromter sketch hangs , says port in use. have changed board in ide mega.

any ideas why this?

many thanks

check mega pin diagram. of pins different. may mean no more calling pin 14 "a0" or 54 in software. if device i2c bus, may need relocate sda , scl lines. see points indicated in communication section of mega board.  spi bus different, not problem.
