I have an application that uses DDE to share information across different programs. I put a DDE link in an Excel spreadsheet and it will continue to update that cell with the value that is sent from the other application. Would anybody know the best way to get that information to the arduino via a serial port?
I've seen applications (expensive ones) that will write Excel spreadsheet cell values to a serial port. But I'd like to make it as simple as possible and not even use Excel if possible.
Here is an example of what I type into an Excel spreadsheet to get the value: here is the format =name|topic!subject?info and here is the actual link =blx8|quote!GOOG?last
That will return the last price of Google's stock. I need to get that value to my arduino. Any ideas?
