I'm going to write an application in VB.net for PC and then connect PC to Fatek FBs via Ethernet and control machine from PC. Can anybody send me an example code with communication PC-Fatek FBs?
Turns out I was wrong, here is an article about talking to Fatek plcs using .net :)

I'm an engineering student, and to be honest a beginner in drivers writing. What i'm trying to achieve right here, is have the titular board talk with my pc over ethernet, so i'm asking for some useful tips regarding the communication setup, like pinging it from my pc.
Many Thanks.
Since LPC1768 doesn't come with a RJ45 jack, you need to somehow connect a RJ45 jack to your mbed. This page may be helpful. https://os.mbed.com/cookbook/Ethernet-RJ45
Once you have physical connection, connecting a mbed device to internet is pretty easy with Mbed OS EthernetInterface library. You can find API and examples here. https://os.mbed.com/docs/mbed-os/v5.12/apis/ethernet.html
Do you need to use Ethernet? Why not using USART directly by using e.g. use a USART to USB converter like the FTDI chip.
I am trying to create a system for controlling my home appliances using arduino over internet.
Arduino Uno will act as a web server and recieve the commands from remote browser.
In doing to I am not sure as how to protect arduino from unauthorized requests from web.
Is there a way to do this, or is there any library available for this. Please suggest.
What i suggest you is to do what a lot of people does, so: use a raspberry (or a beaglebone or another linux embedded board) for the web interface and the arduino for the sensors/actuators.
This way you can install a real webserver, with a lot more functionalities than the bare arduino. You can then interface the webpages to the serial port to send the arduino the commands
I'd like to use my usb 2.0 ports on my Lenovo V570 like Arduino pins, and I'm not sure how to program my computer to do that.
My main goal is to turn the power to the port on and off (w/ code), thus powering whatever electronics I connect to it.
My computer runs Windows 7.
I found some ok ideas on this article:
Controlling voltage supply on usb port using c or any programming language
but I was wondering if anyone had some more ideas.
Thanks.
I have been researching for a couple of days, and i have not found anything I understand about sending direct commands to the NXT via USB. All of the tutorials I have found are based on Bluetooth communication, and the information I have found about USB is always like "Better change to bluetooth", or "Think about it as a COM port"
I had previously sent those commands via Bluetooth, but the connection fails too often to be useful, and is slower than USB.
USB connection is not detected as a COM port, but I know it is posible to control motors and get sensor input with a USB connection, because the LEGO software does so. It has that remote control feature that allows user to activate motors from the PC, and can read sensor input as well.
So, my question is, How can I send and recieve those direct commands via USB? and, Is there any way to do so in Visual Basic 2008?
You can use the MonoBrick Communication Library to do this. See http://www.monobrick.dk/software/monobrick/.
Alternately, you could use the Fantom driver from the official LEGO Software developer kit. http://www.lego.com/en-us/mindstorms/downloads/software/nxt-sdk/
I have a piece of software I have written that talks to a web service over it's Wifi connection on a Casio WinCE handheld.
Unfortunately the Wifi network and the network created by WMDC (or ActiveSync) to host the debugger connection clash, they are both 192.168.55.0/24. So I can't have them both connected at the same time.
Does anybody know if you can reconfigure WMDC to use a different address range?
I've hunted through the registry but can't see anything obvious, and Google is not turning up anything useful.
Thanks,
James.
Is the development PC on teh same network as the WiFi connection? If so, I'd abandon ActiveSync/WMDC altogetehr and just use ethernet debugging over the same connection that it's using for the web service calls.
