![]() ![]() I use a for cycle to send each row of the matrix to the function moveTo() provided by the library to move each motor: the function takes an array as an input which is represented by a single row of the matrix and when all the motors have reached their target, the for loop allow to go to the following line of the matrix and move the motors to the new target. The matrix has a number of rows equal to the number of position to be assumed by the arm and each column represent a single motor (six motors so six columns). I use AccelStepper and MultiStepper libraries because i have six different stepper motors to be controlled and to be moved simultaneously: the motors move a robotic arm. Feel free to ask me any clarifications if you don't understand my problem. At the moment the Arduino receive the message the controller should start the programm to send the data to matLab. As next step I want to send with MatLab a 'start send' message to the Arduino. I did it over the serial Connection without addons. Have you got any suggestions? I know, it's possible to write on the serial port using Matlab but the problem is this one: when I try to print every single value of the Matrix just simply using a for cycle and Serial.print() command I cannot open the serial monitor to verify if the values have been correctly received, because the Serial port has just been opened to begin the communication between Matlab and Arduino. I want that a serial communication with an Arduino. ![]() ![]() I read the string and I newly transform it into a matrix on the Arduino Sketch.Įverything is working well, but I need some code improvements to reduce its own complexity. I use Hyperterminal to send the file on the Serial port I transform the matrix into a string in Matlab Now we need to open the arduino as if it were a file.Hi everyone, I am having the following problem: I calculate a matrix on Matlab and I need to send this matrix to Arduino in order to move my stepper motors. Next set the baud rate you set in the Arduino code above. Set the port to the port you are using to program the Arduino, am using COM4 to program it. MATLAB Serial Classįirst we want to create an object of the class serial. Simply print some data with the Serial.print() function.įor those who haven’t used the serial class before all am doing in the code above is sending the value of the variable i at a baud rate of 9600. If you have used the Serial class of the Arduino before this won’t be new to you. It will send the value of a variable from the Arduino to MATLAB and plot them. I’ve been learning MATLAB lately and playing with the Arduino more and more, then I started to wonder how to make the Arduino communicate with this program, it turns out it’s not hard at all. ![]()
