rossatmsoe 0:ab5b6bca3e25 2 /* MATLAB can send data over to the Nucleo to control its operation or
rossatmsoe 0:ab5b6bca3e25 3 to output data via AnalogOut, etc. In this case, MATLAB sends a number and the
rossatmsoe 0:ab5b6bca3e25 4 onboard LED is set to blink that many times in 2 seconds.

rossatmsoe 1:e9cb1aec787c 6 MATLAB can connect to Nucleo using the serial object defined in MATLAB.
rossatmsoe 1:e9cb1aec787c 7 Here is MATLAB code to send number:
rossatmsoe 1:e9cb1aec787c 8
rossatmsoe 1:e9cb1aec787c 9 >> nucleo = serial('COM3','BaudRate',9600); %(replace with your COM channel)
rossatmsoe 1:e9cb1aec787c 10 >> fopen(nucleo);
rossatmsoe 1:e9cb1aec787c 11 >> fprintf(nucleo,'5\n'); %This line can be repeated with values other than 5
rossatmsoe 1:e9cb1aec787c 12 >> fclose(nucleo); %When you are all done, close connection
rossatmsoe 1:e9cb1aec787c 13 >> clear s; %Clear object from memory
