Error on Matlab/Simulink

Projects Interfacing w/ Software on the Computer

Hi everyone,

I'm using Arduino Uno with Simulink in an application where I have temperature controller. Three Arduino library blocks are used: two analog reads (setpoint via potenciometer and lm35 sensor) and an analog write. When only two of the first blocks are connected, the system works normally. When the third block is connected, the simulation runs and after some seconds the following message is displayed:

Warning: unsuccessful read a timeout occurred before the terminator was reached.

I reconnect Arduino and Matlab, but the problem persists. Can someone here helpe me please???

Thank you

Think this is a matlab forum question as the error message comes from that part.

When the third block is connected, the simulation runs and after some seconds the following message is displayed:

I suggest, then, that you send the data that the matlab program is expecting, before the timeout happens.

Of course, we have no clue what the matlab program is expecting, or what you are sending, so you are on your own with this problem.
