I am trying to send a vector of deciaml numbers to a controller via a USB cable using a Simulink model. I am struggling to establish serial communication with the controller and can't send my generated vector. I tried using the 'Serial Send'-Block in Simulink which I believe can only send binary data. However, I need to send a decimal vector.

Thankful for any help!

Hi Rick,

You could have a look at the following similar queries on MATLAB Answers community:

Writing an array of numbers to serial port - This illustrates the use of 'fwrite' command to accomplish the task of transfering an array of decimal numbers to a serial port.

send array from matlab using serial communication - The solution illustrates the use of 'fprintf' to do the required task.

For more information, you could have a look at the documentation pages of fwrite and fprintf.

Hope it helps!
