matlab to control arduino uno borard,with 3 stepper motors.

hi i want to control 3 nema-17 steppers using arduino,i want to use matlab for the coding. i used a normal cnc shield with a microstepping module a4988.

i followed the tutorial in the mathworks-arduino page,but it did not work.

error message i got was:the 'addOnShield' is not specified,something like that.

pls suggest me the what cnc shield should i use and the microstepping driver i need to use and pls provide their model number or bestbuy links.

thanks.

I assume that you have already installed the hardware support package- ‘’MATLAB Support Package for Arduino Hardware.”

I would suggest you use Adafruit Motor Shield V2. Adafruit Motor Shield V2 is an add-on shield that you can plug into Arduino Uno.

You can create a motorshieldv2 object using the add-on shield specified above and connect a stepper motor to the appropriate pins on the motor shield. For stepper motor connection use stepper object.

thanks sir,can u tell the syntax for microstepping in matlab.

does adafruit shield have the ability to do microstepping inbuilt in it,if then how to do that,or should i get a microstepping module seperately.

if i need to get seperate microstepping modules,how to connect them to adafruit shield.

will i be able to operate the microstepping modules with motor without the adafruit shield.

thanks in advance :)

i read the documentation of shield and stepper.

is it possible to do microstepping by increasing the 'number of steps per revolution ' specified.

motor = stepper(shield,1,4000{steps per revolution},'step type','Microstep')

how to go about the hardware connections for microstepping?

since adafruit shield can control only 2 motors at a time,is there any other way to control 3 motors simultaneously.

for my project i need to control 3 motors.

thanks.
