new device driver - how to access 8 bit registers in labview 7

[Uri]

Hello
I'm writing my own driver to a new DAQ card that has 8 memory mapped hardware registers. Since each needs different data at different time , i need to write 8 bits data to each register. I tried the IN_port and OUT_port commands , but they only take I32 or I16 data , while i want to read/write I8 data as not to disturb the adjacent registers.
Any help ??

In Port and Out Port take I8, I16, and I32. They are polymorphic as the context help explains. All you have to do is right click on the function and choose Select Type or just use a constant/control of the representation that you want.
