[alexde]

after reciving data from visa (recived data from xbee) i try to show it on a waveform

all wires are ok but no data is recived (i chaked the visa is transfering data proporly)

pleas help me to solve this

Hi Alex,

- get rid of that ConvertToDynamicDatatype...

- attach your VI with actual data (set to default with data in all controls)

- do you spot the red dot? Do you kow its meaning?

First try to store locally into an string.Check whether its going wrong then try to debug. It works fine. Let me know if it doesnt

[alexde]

Thanks for the fast responses

get rid of that ConvertToDynamicDatatype

I can see data but I get it in spikes and not as a normal waveform in time (every new value gets to t=0 x=num)

what am I doing wrong ?

Thanks in advance

Hi alex,

your signal coming from VISA only contains a single (scalar) value that is making up your waveform.

Maybe you want to collect more than one point from your DAQ device before building a waveform from it?

I have no problem with collecting some together. Expect I don't know how to put it in a FIFO

Hi alex,

when you don't have any problems collecting data then you should use a shift register somewhere in your code...
