Arduino Simulink Serial Communication

<<

Hi ;

I am using the models above. I am transmitting constant 100 to arduino, but I cannot read 100 on the receive scopes. I uploaded them separately and I also uploaded them in the same model. I couldn't read 100 in both ways. What could be wrong?

Thank you.

To the top right of the 'Serial Transmit' and 'Serial Receive' blocks, it says 'ARDUINO'. This means that these blocks execute only inside ARDUINO hardware. You will not be able to use scopes to see the value sent or received by ARDUINO's serial port.

If you would like to transmit '100' serially to any hardware, you have to use 'Serial Configuration' and 'Serial Send' blocks in 'Instrument Control Toolbox'. Also to receive data serially from any hardware, use 'Serial Receive' in the same toolbox.

Hope this helps.

It is perfectly valid to scope the input that will be sent to the Arduino blocks.

Hello Everybody /r/matlab, i have a real big issue to discuss as i couldn't find any solution for that problem in google. I have a Simulink Modell where i want to receive data from a Host PC connected via USB to the ArduinoMega. This data will go to several digital outputs to control LEDs,Servo etc.. When i use the Serial Receive block from the arduino support package i am able to get one Signal from the host PC via a second simulink model. I tried to connect a demux block to the Serial Receive block of the Arduino Model to receive multiple data. I get the following error: Error in port widths or dimensions. Output port 1 of 'arduino_servo/Serial Receive' is a one dimensional vector with 1 elements. and Invalid setting for input port dimensions of 'arduino_servo/Demux'. The dimensions are being set to 1. This is not valid because the total number of input and output elements are not the same. Did anybody ever tried out to control multiple outputs in that way?
