    Some variables in the cbus c library are defined as bitfield. I am trying to compile these libraries with a compiler that does not include the bitfield type.
    Does any know know if I can replace the type of this variables with regular int ? It could be that the bitfield type is used to save memory space ... or it could be that there is some "clever" use pointers somewhere in the code that manipulates several bitfield variables as one int.

    The bitfields are used to save space on small micros.

    You can remove the ": n" part in each declaration, which allocates a certain number of bits.

    The RAM usage will blow out by doing this, but it should otherwise work fine.
