I have been tinkering with rs485 serial bus.

My message is 7 byte array with layout

uint8 address uint8 command int32 data uint8 checksum

I now serialize and deserialize the int32 with bitshifting.

Would it be computationally more efficient to use a union of struct and array than to do the bitwise operations?
