Matlab is one big tool which you can play with.. Matlab can be configured to read serial data that can be send through a microcontroller. Here is the code for Matlab to read a single line and print. Assume that you are sending ascii character values through microcontroller separated by new line. Here is the Matlab code to receive the data. 1: obj1 = instrfind( 'Type', 'serial', 'Port', 'COM13', 'Tag', ''); 2: % Create the serial port object if it does not exist 3: % otherwise use the object that was found. 4: if isempty(obj1) 5: obj1 = serial( 'COM13'); 6: else 7: fclose(obj1); 8: obj1 = obj1(1) 9: end 10: obj1.BaudRate=4800; 11: set (obj1, 'Parity', 'even'); 12: set (obj1, 'StopBits', 2.0); 13: fopen(obj1); 14: data1=fscanf(obj1, '%s'); 15: data1=fscanf(obj1, '%s'); %Assume that you are sending characters and 8 bit binary no....
