NathanB. Thank you for your attention and your answer will be very helpful for me!
Viewing the file you sent me I pecebi whose insert (write) the value in a particular register. Very interesting and I really did not know it, exactly because I am new to LabVIEW and more in the LIFA.
About the address being a startup and another time to read, is really strange, this is what is confusing me more, but that's what I understood the code I posted above (http://randomhacksofboredom.blogspot.com.br/2009/06/wii-motion-plus-arduino-love.html). I must have mistaken me for interpretation.
In short, thank you for your help NathanB.!
Best regards,
Henrique
