MATLAB Language Using serial ports Writing to the serial port
Example
Assuming you created the serial port object s as in this example, then
% Write one byte
fwrite(s, 255);
% Write one 16-bit signed integer
fwrite(s, 32767, 'int16');
% Write an array of unsigned 8-bit integers
fwrite(s,[48 49 50],'uchar');
% Close the serial port
fclose(s);
