already i have installed hardware support package, and polulu cp2102 device driver. i mentioned proper communication port number. but when i'm running my arduino model from matlab it throws an error that can't detect arduino hardware.

i included the screen shot. even i connected arduino uno board it throws this error. how to solve this?

I do not have any suggestions on your difficulty about Arduino.

As something that is unconnected to Arduino: I notice that some of your graphics features have been disabled. You might need a newer graphics driver, or possibly you have a very old operating system or possibly you have a graphics card that has some broken features or possibly you have a very old graphics card. You can get more information about the graphics difficulty you are having by read the opengl() documentation about Advanced Graphics Features

Hi,

for the first call you need to specify model and port, something like

a = arduino('nano', 'COM3');

The information is stored in the preferences so that for subsequent calls a simple call

a = arduino

will suffice.

thank you for your response. i'm using 64 bit operating system. somebody told that there is communication port problem while using 64bit os,so that this problem occurs. try on 32 bit os. is this correct?
