What data prepared by you? You're assigning to an int16_t and hoping that specific bit fields map to specific bits. That's just non-portable.

We don't want code that does that. The fact that you had to replicate 1018 lines of code should have been a hint that you're doing it wrong.

Take Peter's advice and use extract32.
