Arduino and Visual Basic Part 1 Receiving Data From the Arduino. After creating the drop. Controller. BT app and realizing how much easier controlling the drop. Controller device is through the app I started to think about creating a PC app. I havent 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 Serial Port Readline' title='Visual Basic Serial Port Readline' />Visual Basic Serial Port Readline ExampleTo test that the sketch is working you can open the serial monitor You are likely to be using a different COM port. The Visual Basic Program. Here is the form. Visual Basic comes as part of Microsofts 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. I have managed to identify both drives and serial ports in visual C express but I still cannot access a specific device RepRap Printer. I would like to send an. Visual Studio Express is a striped down version of the larger packages and has some major limitations. Visual Studio 2. 01. 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 2. 01. Community is available for download at https www. Visual Basic Serial Port Readline In RThe 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 http go. The main download page is at https www. 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 2. Communication. The example uses a very simply form and shows what ever it recieves from the Arduino in a text box.

To test that the sketch is working you can open the serial monitor You are likely to be using a different COM port. The Visual Basic Program.

PORT is the COM port selected by the user and should be the one the Arduino is connected to. Data is the data received on the selected COM port. Typing Tutor For Windows Xp here. Dim com. PORT As. String. Dim received. Data As. String  When the program is first run, the Form. Load subroutine populates the COM port combo box drop down list with the available COM ports. The program then waits for the user to pick one. Private. Sub Form. LoadBy. Val sender As System. Object, By. Val e As System. Event. Args Handles My. Base. Load. Timer. Enabled False. com. PORT For. Each sp As. String. In My. Computer. Ports. Serial. Port. Names. com. PortCombo. Box. Items. Addsp. Next. End. Sub When the user selects a COM port, the value is copied to the variable com. PORT. This is not really necessary as the selected value can be read from the combo box but I like to keep this kind of data in easy to use variables. Private Sub com. PortCombo. BoxSelected. Index. Changedsender As Object, e As Event. Args Handles com. PortCombo. Box. Selected. Index. Changed. If com. PortCombo. Box. Selected. Mike Portnoy Drum Anthology Pdf To Word more. Item lt Then. PORT com. PortCombo. Box. Selected. Item. End Sub Sub connectBTNClick triggers when the user clicks on the Connect button. The first thing the routine does is determine if the user is connecting or dis connecting. The same button is used for both. If connecting, and com. PORT is not empty, then the serial port properties are set, the serial port is opened and the timer is started. To show that the timer is active the timer label is updated to Timer ON. If com. PORT is empty a message is displayed telling the user to select a COM port first. If dis connecting, the serial port is closed, the timer is stopped and the timer label is updated to Timer OFF. The Timer label is there purely for debugging. Private. Sub connectBTNClicksender As. Object, e As Event. Args Handles connectBTN. Click. If connectBTN. Text Connect Then. If com. PORT lt Then.
