Hi,

To write arrays to Arduino from MATLAB open a serial connection and connect it to Arduino and then write using ‘fwrite’. For establishing serial communication,

arduino = serial('COMx'); 
set(arduino,'DataBits',8);
set(arduino,'StopBits',1);
set(arduino,'BaudRate',9600);
set(arduino,'Parity','none');
fopen(arduino);

and write using

data=1:9;
fwrite(Arduino,data,'uint16');

Hi, sorry I have a question:

If one uses uint16 as the data type what is the structure of the communication? Is it startbit, 8 databits,stopbit,startbit,8 databits,stopbit? Or startbit,16 data bits, stop bit ? Im using an FPGA and my Rs232 communication works for 8 bits but not for 16 bits so I suspect that the structure is not the second one I mentioned
