/*  MATLAB can send data over to the Nucleo to control its operation or
to output data via AnalogOut, etc.  In this case, MATLAB sends a number and the
onboard LED is set to blink that many times in 2 seconds.

MATLAB can connect to Nucleo using the serial object defined in MATLAB.
Here is MATLAB code to send number:

>> nucleo = serial('COM3','BaudRate',9600);     %(replace with your COM channel)
>> fopen(nucleo);
>> fprintf(nucleo,'5\n');  %This line can be repeated with values other than 5
>> fclose(nucleo);         %When you are all done, close connection
>> clear s;                %Clear object from memory
