Group several lines in different ports

[ying]

Experts:

I used the Labview andI met a problem by group several lines in different ports. For example, I had 11 address lines, there are 8 in port C and 3 in port D. I want to group them into a group. I used the group configration and group write function to write signal to those lines. But it seems didn't work. Plese gave me some suggestion. Thanks!

Typcially, when you group multiple ports together the port or channel size should be multiple of 8. This means that if you want to group 11 lines together, you will have to group port C and D, a total of 16 lines together. When you read from those 16 lines, you can ignore the upper 5 bits of data. When you write to those 16 lines, you can write zero to the upper 5 bits.
