With the Configure Serial Port, enable the termination character. I have done probes into this program and noticed that the Bytes at Port, when working jump up to about 70 and back to 0 every second or two seconds. I was also wondering if I don’t need something like a “Handshake” between LabView and Arduino to make sure the Serial Connection is set up properly before I start reading out data? I have the Heise connected to the serial end of the cable and the usb connected to my computer. The driver is a DLL of some sort?

I do not have a very extensive knowledge of Labview. That aside, does a default constant allow for the proper declaration of termination char? I am using a visa port and I know to open sfrial close the visa port labview serial port and again while the programm is running is bad style.

Message 5 of For two ports to communicate, both the instrument and the controlling computer must have the same baud rate, labview serial port bit size, stop bits, and parity. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type.

Message 4 of 4.

In order to help you, you need to supply more specific information. All data setial are converted to strings of ASCII characters and then transmitted bit by bit across the serial bus.

Message 5 of Message 6 of Can anyone help me how to improve my code? There are only two ways to tell somebody thanks: The resulting data should transmit once every second and appear like the following: That doesn’t allow your code to perform any cleanups. Still can’t do it.

Labview serial port am looking for any assistance that anyone may be able to provide for successfully reading a lavview standard reading from a COM port. The only hardware setup required is connecting the serial cable to the serial port on the PC and the serial port on the instrument. I have two last questions about the serial communication, I tried to simply print out three values like this:.
