No value from I/O

[Leonhard_94]

Hey Guys,

I have the following problem by taking a measurement in FPGA mode.

My programm is based on the NI Tutorial:

https://knowledge.ni.com/KnowledgeArticleDetails?id=kA03q000000x3ruCAA&l=en-US

In the result the sensors do not measure anything (except 0).

I don't understand why, do you have any ideas?

Thanks

Hi Leonhard,

your FPGA.vi looks like this on my computer:

No wonder you don't receive any (senseful) data from your FPGA…

I tried to delete the I/Os and apply them again and somehow I uploaded the version where the sensors are deleted.

My mistake, I am sorry.

Hi Leonhard,

In the result the sensors do not measure anything (except 0).

Do you get any errors when running your code?

Which value do you set for "Count(uSec)" in the RT VI? (I hope it's not zero…)

Are there remaining elements in the FPGA FIFO?

Is there a FIFO overflow?

Btw. the FIFO datatype doesn't fit with the datatype of those AI channels as can be seen by the coercion dot.
