| one of your functions is too large. Try splitting it up. |

post the code so we can see if we can see anything then. Hard to tell without seeing it.
Also post your compiler version just in case. |

You may be suprised.
You can (for instance), write hugely long functions that result in quite small code (lots of simple input/output instructions), or conversely, write a 'one liner', that uses a huge amount of code space.
Printf statements are bulky, as are floating point arithmetic.

The compiler likes to in-line function calls and that can make for lots of ROM use. Generally if the called function is only used in that one place then it will get in-line'd
I think there is a # directive that can be used to prevent automatic in-lining of code.

| Look up #separate and #inline in the CCS manual |

If you call a function once the compiler will inline it. But if you call a function once and you're running out of space in that page then it will realize this and make it separate automatically. |
