Picking up a value from an Arduino in Matlab

Hi

Is anyone able to provide any help in regards how I can continuously pick up a value from the arduino and output it in Matlab?

I know you send the data via a Serial.println(GS);

I just want to know how to pick up the value for GS continuously in Matlab.

Additional Information:

I am unsure how to code a colour sensor in Matlab and have hence used an arduino. In my code I have converted a colour sensor into a grey-scale value ranging from 0-255. What I want to be able to do is receive this value continuously to Matlab. I am however unsure in the method of achieving this.

Any help would be greatly appreciated.

Thanks.

Try the MATLAB Arduino Support Package that comes with base MATLAB. See the link below,

http://www.mathworks.com/hardware-support/arduino-matlab.html

It allows you to get data from pins and also I2C and SPI buses on Arduino into MATLAB. You would need to write a loop to keep calling the MATLAB functions if multiple readings are needed in your application.

Hi, i have the same question as Philip. I tried reading the pins using the Matlab support package, but it works too slow for what i need (rotary encoder). so im still trying to find a way to get arduino to share the value of variables.
