Vba For Excel Serial Communication With Arduino

Vba For Excel Serial Communication With Arduino Average ratng: 4,4/5 7077 reviews

I'm looking for a way to communicate through the serial port while in Excel. I used to use Excel 2003, and had MSComm objects setup to work within my code. With these objects, I was able to trap on incomming comm events and parse any new data that was coming from the serial port. However, when I moved over to Excl 2007, the MSComm object seems to have gone away, and I can't find any.

    OK. So I've finally figured out how to read a com port with vba+


    Download free software lectra romans cad free. How to Read Com port I can post my code below .. It works, however, you need something going over the com port or you can't use this. What I'm doing is an Arduino project that sends data back over the serial port ( com4 in this case ) and its output is below the code.


    What I need to know. Is how do I figure out the number of bytes to get from the port ( it's set from the example @ 64 ) from the displayed output how do I decide how many to get. OR better .. how do I 'watch' the com port and have it tell me it has msg ready.


    I'll just attach the workbook instead of code!



    The following is the output from the arduino!
    Sample DHT11..
    Sample RAW Bits: 0011 1000 0000 0000 0001 0010 0000 0000 0100 1010
    Sample OK: 18 *C, 50 *F, 56 %

When you think about serial communications, Microsoft Excel isn’t typically the first program that springs to mind. But this spreadsheet has a rather powerful scripting language hidden away inside it, which can, with a little coding, be used to send and receive data over your serial port. The scripting language is called Visual Basic for Applications (VBA), and it has been a part of Microsoft’s Office suite since 1993. Since then, it has evolved into a powerful (if sometimes frustrating) language that offers a subset of the features from Visual Basic.

It can be a useful tool. Imagine, for instance, that you are logging data from an instrument that has a serial port (or even an emulated one over USB). With a bit of VBA, you could create a spreadsheet that talks to the instrument directly, grabbing the data and processing it as required straight into the spreadsheet. It’s a handy trick that I have used myself several times, and [Maurizio] does a nice job of explaining how the code works, and how to integrate this code into Excel.

If you’re looking for other ways to leverage this Excel feature, consider watching movies at work or building a virtual machine inside of your sheets. Admtek an983b driver windows 7 download.
