Simulink IO enabled error on Arduino Uno

69 views (last 30 days)
I am trying to use the Simulink IO enabled feature in MATLAB 2018a. The platform is an Arduino Uno. Even with the simplest example, for instance trying to read from pin 4 and displaying it I get an error although simulation mode works fine without IO enabled, and when I load the program onto the hardware it also works fine. Here is error that I see when I enable Simulink IO:
MATLAB System block 'blink2/Digital Input/Digital Input' error occurred when invoking 'setupImpl' method of 'codertarget.arduinobase.blocks.DigitalRead'. The error was thrown from '

Caused by:
Transport layer object is corrupted. Try fclose(instrfind) and delete(instrfind) and then create a new hardware object

Did you try fclose(instrfind) and delete(instrfind)? That should work.

I am trying run arduino_communication in normal mode with Simulink and I get same error:

*Caused by:
Transport layer object is corrupted.* Try fclose(instrfind) and delete(instrfind) and then create a new hardware object
After
fclose(instrfind)
delete(instrfind)
I get

*Caused by:
Instrument object OBJ is an invalid object.*

I have found that the problem was using a Sparkfun Redboard, which is an Arduino Uno clone. It uses a different serial port. Once I switched to an Arduino Uno the problem resovled.

Try clearing the workspace. Try clear all, clear classes. Also try disconnecting the board and reconnecting it once.

Hello, have the same problem here. Was it really the "incompatible" uno-board?

I have the same errors. Did you solve the problem?

Me too.
I'm trying to read data from A4, then do some fancy stuff with FFT and then light up a led in D10.
I'm using Matlab 2018A with Arduino (Elegoo) Mega 2560

Edit: It seems that disabling Simulink I/O made the error go away. Go figure.
