OK, I found the repository. Next time I'll check that first (if there is a 
link),
If you want to combine negative and positive numbers you have to 
explicitly convert negative numbers to their 2's complement first.
I assume that the positive numbers are < 2**(10-1)?
If you later want to extract a 10 bit value you have to explicitly convert 
the 2's complement into a normal integer to get the sign back.
