![]() ![]() I have a simple Arduino sketch that collects values from a sensor and send them via serial. 'Serial read' is never displayed.Īny help would be appreciated, thanks in advance. I have some issues in a simple Arduino - Matlab (both 20) serial communication. The matlab code executes and I get the message box telling me that it has initialised, however the variable a is not read successfully and the while loop exits prematurely, debugging I found that it actually only loops for one iteration and then continues. In this sensitive time, if it gets flooded by data coming in from Matlab, it might behave unpredictably. When it does so, it conducts some mysterious dialogue with the operating system of the computer. Mxbox = msgbox('Serial Communication Initialized') uiwait(mxbox) This is because everytime Matlab opens communication with Arduino, the Arduino reboots. % VERIFY SERIAL COMMUNICATION HAS BEEN SETUP void setup()Īnd my matlab code: delete(instrfindall) Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. 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.I am trying to get some basic serial communication up and running. A tag already exists with the provided branch name. 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. 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 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 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. ![]()
