Cannot program Arduino Uno Board

Hi, I'm facing problem to connect my Arduino Uno board using MATLAB. I have search around the internet for around 7 hours and still cannot find the solution. I am really in big problem, I need to for my assignment. Can anyone help me please?

>> a = arduino();
Updating server code on board Uno (COM23). Please wait (might take a few minutes).
Cannot program board Uno (COM23). Please make sure the board is supported and the port and board type are
correct. For more information, see Arduino Hardware Troubleshooting.

I have tried changing the name of C:\User\user_name\Documents\Arduino file to other name but when I run the program again a new Arduino file is created in C:\User\user_name\Documents\.

this is my a = arduino('COM23','Uno','Trace',true)

Answer 1

[Rajat Ligade]

I had Tx and Rx pins connected to something. I removed those pins and reran the code. the error is gone

[Bart Kieviet]

This solved the above problem for me.

[Mohd Hairi Mohd Zaman]

This action solved my same issue too. After removing and reran the code, I reconnect those Tx & Rx pins again. No more error after that.

[zhe cheng]

change the port

it helps.

[José Moreno]

Thanks, I try it and it was the solution

Can you first confirm that the downloaded Arduino IDE works fine on your computer? To do that, go to the folder which is returned by typing "arduinoio.IDERoot" in MATLAB and then open the IDE manually. Try upload an empty sketch to the same board and see if you get the same error.

If yes, check if you have write permission to this folder C:\Users\ACER\AppData\Local\Temp\

[Liew Yean Choon]

After uninstalling everything in my computer, I have it works several times. But when I reinstalling the Arduino IDE and write a code into my arduino uno, now the MATLAB fails again.

This is my own error message:

Updating server code on board Uno (COM5). Please wait.

First input can not be empty. Expected a non-empty string or a valid file-id.

[Rushabh Kalmate]

i am facing exact same error , can you please tell me how it is solved ??

[Rushabh Kalmate]

After sucessesfull installation of support package for arduino hardware , i am facing problem for hardware setup . i have choosen usb cable type connection , After selecting correct board "uno" and port "COM7" and clicking on programme it is showing "First input can not be empty. Expected a non-empty character vector or a valid file-id."

[Luis Delfin Puron]

I was facing the same problem and solved it by setting the variable arduinoio.IDERoot to an address which current user has access to read and write. In my case it was: arduinoio.IDERoot = 'C:\\Program Files (x86)\\Arduino' Hope it helps.

[fatima zohra soussi]

i dont understand what i should do i have same problem ?

Answer 5

[Ogheneovo Idolor]

Try running MATLAB as Admin. Worked for me.

Answer 6

[ybshokouhi]

I am having the same problem. Any updates on this?

[adrian paeckel]

I had the same problem. When trying to program my arduino mega 2560 on MATLAB I would see the Adruino IDE logo for a few moments before the error raised. The problem and solution I found is that I had installed an earlier version of the Arduino IDE on my Mac but the IDE contained in the Support Package on MATLB was an older one. So I replaced the old one, contained in the address which you get typing arduinoio.IDERoot in MATLAB command, for the latest one and it works fine now.

Answer 7

[Andrew Loots]

I have Aduion Uno and it loads fine if I do not load the Paulstoffregen/One Wire library. As soon as I add the library it throws the' cannot program board " error.

Please help
