FPGA Analog Output Problem

[GoodTime]

I wrote code for PXI-7831R(FPGA) Analog Output.

When i excute under Labview environment, this code is no problem.

But, when i make excutable file, FPGA Card don't output minus voltage. (puls voltage is no problem)

What's problem ??

Hi GoodTime,

Can you post your code?

[GoodTime]

Thank for your reply, SandmanUK.

i found solution for the problem last night.

i connected numerical result (double type) directly to FPGA Analog Output.

So, i inserted  numeric conversion (To word integer), then the problem disappear.

i think  auto type-conversion-mechanism of LV have internal Bug.

--- between "LV Environment" and  "Start Up Excutable"

Hi,

I see. I don't think that the FPGA supports double types.
