convert binary string into integer

[bus monitor]

Does anybody know how to convert a 15 bit binary string into an sign integer with the MSB as the sign bit?

so for example if I receive:

111-1111-1111-1111 => -1

111-1111-1111-1110 => -2

000-0000-0000-0001 => 1

000-0000-0000-0011 => 3

Thank you

Hello,

I'm not terribly proud of the implementation (it's not as clean as I'd like it) but I think it's what you want (interprets/converts the pattern you described).  The comments on the block diagram explain the procedure for producing the results.  It should work with or without "-" delimited binary strings, and is not restricted to 15 digit strings.

I hope this helps!
