Hi, i;m working with LV2009 32b,Windows 7 64b edition, my NXT firmware is 1.28. Problem is that i can't communicate nxt brick with pcf8574P I/O. I have 82k pullups resistors.I attached my code.I hope that someone help me ;(
The problem persists even after changing Os to 32 bit Windows Xp virtual machine. All I get is -35 Error code (according data sheet:last transaction failed). I have no idea what could be wrong
what version of LabVIEW NXT Module do you have?
Could you give me more details about your setup?
Have you tried using the examples that are included in the LV NXT Module?
