Integration of Mavlink and LabView - labview

I'm using mavlink with a pixhawk flight controller. I want to send and receive packets of data to and from LabView to mavlink. How can I create a link between mavlink and LabView?

MAVLink has a C-library so you should be able to call that from LabView using the Call Library Function Node.

send data to serial Keil uvision

I am looking for a GUI window in Keil uvision4 to send data to the serial. When I open serial window (USART #1-3), I am not able to type any characters on the screen to send to the serial.
Is there a way to manually type data that will be seen by the simulating environment (uvision) as having been received on the serial port?
The serial window should do what you're asking for in simulation. You may need to confirm that you have correctly configured your simulation, and the serial port you're using is the same one which you are monitoring in software.

USB packet and data buffer capture

I need a software or application with API support to capture USB packet and data buffer. I would like to analyse the captured data using LabVIEW.
Suggest applications for usb packet and data capture with API support, so that I can access them using LabVIEW.
Or
Alternate methods to capture and analyse usb data using LabVIEW
I had tried a approach using logman.exe . But that doesn't log all the USB packets. Has anyone tried logman to capture the usb packets?
you can consider using VISA functions.
A few examples are shipped with Labview (open example finder and look for USB).
Here is a starting point giving instructions about how to give VISA access to the device.
You need find out some windows dll's and use it in labview. the examples provided for NI USB devices.

create a program that communicate with the arduino using VB.net

I have to create a program that send comand to the arduino;
The program must be the client and the arduino the server.
So the question is: what is the code to start the communication?
P.S. the arduino obviously have an ethernet shield on it.
I have searched on google, i found this :
For Arduino :

For Windows :

I've not used Arduino myself but a have a look at Arduino Playground:
CmdMessenger is a messaging library for the Arduino Platform (and .NET/Mono platform). It uses the serial port as transport layer. To use CmdMessenger, we define a list of command identifiers, then attach callback / handler functions for received messages.
The message format is: Cmd Id, param 1, [...] , param N;
The library gives the following functionality:
Sending and receiving commands
Calling of associated functions on received commands
Sending and receiving zero to many arguments per command
Sending and receiving of all primary types. This includes bytes, longs, ints, floats and doubles.
Sending and receiving in plain text form (human readable, robust) or in binary form (efficient)
The library can be downloaded through the Arduino or PlatformIO library manager, or downloaded as a stand-alone package, see the read-me page.

How to create a USB STACK using win32 programming

I am doing my Project using win 32 programming.I am just learning about win32 programming and able to create an UI.I want to communicate with an USB Device with that UI.SO,How can i go for that?Is there any predefined functions will be there are we need to create the function for communicating with the OS and get the devices List and got the details about them.
My purpose is to ,
1.Creating an UI that tells about the Basic information about the device.
2.For that first of all i want to communicate with the OS for device attachment and find the drivers for that.That will lead to get the information about the device and communicate with the device using that UI.
So,can anyone help me about this?How can i achieve this or approach this?
Assuming your USB Device enumerates as a vendor specific device and not a class that has a preloaded driver WinUSB would be perfect for your case. If it is loading a class driver such as HID or some other class you will need to look up the API for that type of device on MSDN.

Communication With Siemens S7300 PLC through PC Ethernet Port

I have got a Siemens PLC (S7 315-2 PN/DP PLC), which has got a built in Ethernet port.
I want to establish communication between PLC and my PC through TCP/IP (VB.NET based program).
How can it be done ? is any demo or example program available for this ?
Try also Snap7, 32/64 bit with .NET/mono wrappers ready
Libnodave has examples for many languages and VB.NET is one of them. I have used it a lot my self with Pascal and C.
If you want to send data based on events you could also use the 315's build-in Ethernet cummunication blocks and send a data packet (like emulated XML or JSON) each time something interresting happens. I did it a few times and it works very well.
