Open failed: Port: COM7 is not available. No ports are available. Use INSTRFIND to determine if other instrument objects are connected to the requested device.What might be a proper reason?
What is especially IMPORTANT about your problem?This seems to me to be a Matlab problem and if it was my problem I would be consulting a Matlab forum....R
Open failed: Port: COM7 is not available
And it is IMPORTANT for sure since I have a presentation in a university in 3 days.
The error you posted in your Original Post is not an Arduino errorIt is a PC/Matlab error.Perhaps you meant to say "Urgent" - if you are at university I would expect you to know the differenceBut it is not our problem that you left it so late to figure out a solution. And your question is no more (or less) important than any other question here....R
perhaps you know nothing about this?
You are quite right. I don't know Matlab, or Windows for that matter.I have been trying (with complete lack of success) to suggest that you ask your question where you are more likely to meet someone that knows Matlab....R
Is there some particular reason that Matlab has to write to a SD card on an Arduino shield?Isn't writing to an SD card on the PC running the Matlab enough?
If you want the code to do this, then feel free to ask for someone to write this for you (Though you may find that you will be parting with some cash) - If you need help, post the code you have attempted so far, and you may find that we are more likely to help polite people.We help because we want to, not because you demand it.
No it is not, you see, I used Arduino SD card in order to connect arduino to my application via Bluetooth...This is the idea in general, I take the results from Matlab in a text file, then put the text file in Arduino SD card, then open the text file using SD.open(), read the results and send them to the application via Bluetooth HC-06. I already solved the bluetooth connection, but all I need is to know how to get the results and read them.. I'd be glad if anyone helped me, It'd save my life really...
so I was trying to reach the Arduino SD card directly from Matlab itself.
