Hello,
You mention that you send a string to the microprocessor that tells it
how many bytes to send. Instead of requesting 512 bytes, try reading
10 times and only requesting about 50 bytes at a time.
If that doesn=92t help, try directly communicating with your
microprocessor through HyperTermi
Hello Thijs,
The "Port List" connection of the DIO Config.VI should be wired with
an array of the digital ports you wish to use. Each port has 8
digital lines.
Unfortunately, the E-series devices do not support hardware-timed
digital I/O. You could still output your points in a software loop,

Hello,
Are you referring to the scroll bars on the front panel or the block
diagram? By design, the scrollbars become disabled when the entire
front panel or diagram fits in the window. As you've discovered,
moving an object close to the edge of the window will cause the
scrollbars to become ena
Hello,
Dennis is correct; a local variable will force a copy of the data. In
general, LabVIEW will try to do an in-place replacement whenever
possible. However, depending on what is happening with the data
before and after the replacement, LabVIEW may make a copy.

Can you elaborate what you mean by the system is lost?
Ben has suggested a good idea of posting the code in question. It
would also be helpful to know which version of LabVIEW you are using
and which serial VIs you are using. His clarification of the timeout

Can you provide any additional information about this memory error
such as the error message? Also, is this a LabVIEW memory error or a
Windows memory error?
Crashes in LabVIEW when working with CINs are frequently caused by
errors in the C code of the CIN. Since a crash doesn't happen f

A good place to start for example code is the product manufacturer and
it seems like you have already done that. National Instruments also
provides example code we have created as well as from other users.

I am not familiar with the databound grid control you refer to or with
databases in general. However, instead of recreating its
functionality, you could look into the LabVIEW Database Connectivity
Toolkit which simplifies database communication. You can find out
