Data transfer from RT to FPGA using DMA FIFO

Question

Hello all,
My question is "How do you stream data from RT target to FPGA target using DMA FIFOs?"
I would like to control some indicators (or controls) in FPGA vi using controls in the RT vi using DMA FIFO.
I have used four controls in my RT vi, but I get only one indicator out on my FPGA vi. (I would actually like to use some controls on the FPGA target using controls on the RT target)
Is this possible?
Can anyone help me with this?
I have attached my vi s.

Based purely on your example, I see two options:
1. Do as RavensFan suggests and use Boolean Array To Number to send a single number down to the FPGA.  Your FPGA can break up the number easily enough to update the indicators.
2. Just write dirctly to the indicators.  I do not see a need for the DMA.  Again, based purely on your example.
