Visual Foxpro Serial Communication Arduino And Processing

I'm using a VS WinForms app to communicate with my arduino project. Hack de yang metin2 mania sites 2017. I am using simple serial.WriteLine() and ReadLine() on both ends. Using any Arduino board works, except for the Leonardo/Micro which is critical to my project. Actually I am using the Micro Pro with the Leonardo bootloader. In my sketch I did include 'while (!Serial);' in setup(); Using an Uno/Mega2560/etc I get perfect results. When I try to use the same sketch with the same WinForm on a Micro Pro board I get no response. Post the programs that you are using.

A key difference between the Leonardo/Micro and the Uno/Mega is that the latter resets when the PC program opens the Serial port and the former does not. It can make the Leonardo/Micro a bit of a PITA to work with.

You can force the Micro to reset by opening the serial port at 1200 baud, closing it again and then opening it at your desired baud rate. I am no longer familiar with Windows but for communicating with an Arduino with my Python and Ruby programs my Arduino program has something like Serial.println('Arduino is ready'); in setup() and my PC program waits until it receives that before trying to communicate with the Arduino. This should illustrate the idea.R. First allow me to say how great this forum and community is!

I've been an avid AVR user for some time and these forums are always kind and helpful. I had nearly forgotten about the AVR reset upon serial connection on the uno/mega, thanks for the reminder.

I need the micro/leonardo in order to use the HID features, namely the keyboard emulation. And I get the added benefit of the board not resetting every time I connect. I'm using Visual Studio 2015/WinForms/C# and Arduino IDE 1.5+.

I may try moving to the Visual Micro plugin so the Arduino IDE lives in VS. I suspected it could have something to do with the setup of my C# serial port, so thanks Paul for the advice. I will try that first and let you guys know what happens. Also nice to know about the 1200 baud reset trick. That may come in handy.

Thanks all for the advice.

After creating the dropControllerBT app and realizing how much easier controlling the dropController device is through the app I started to think about creating a PC app. I haven’t done any PC programming for many years and so I looked at what various options are currently available. Visual Basic kept being recommended for ease of use and quick development. Visual Basic comes as part of Microsoft’s Visual Studio Suite and I initially download and played with Visual Studio Express which in turn lead to Visual Studio Community. Both are free for personal use. Visual Studio Express is a striped down version of the larger packages and has some major limitations. Visual Studio 2013 Community, on the other hand, is a full featured IDE and development system free to use for students, open source contributors and small development teams.

It includes several languages but for now I am only interested in Visual Basic. Visual Studio 2013 Community is available for download at. The download is just the installer which will download the main program from the internet.

If, like me, you prefer an off line installer, you can get one at The main download page is at After installing the software it took me a while and many Google searches before I started to figure out the IDE. For me, fully learning the IDE is beyond what I want and have time for but over the course of a weekend I managed to create my first working program. A simple example of receiving data from the Arduino. Arduino to Visual Basic 2013 Communication The example uses a very simply form and shows what ever it recieves from the Arduino in a text box. The Arduino Sketch The Arduino Sketch sends the string “1234” over the serial connection once every second. At the same time it blinks the built in LED on pin 13.
