hi ,,,i want a code for working matlab with digilent device

i m working on Matlab with Digilent Device.I hav biosensor to sense the voltage value and plot.i wanna stop the process after some specified seconds(because the output is keep on changing,i couldnt retrive the data).how can get this through code?also,wanna collect the datas for specified time intervals alone.?help me to achieve this through code?

How does the manufacturer recommend that you communicate with the device? Through USB? Do you have the Data Acquisition Toolbox? If the manufacturer supplies a DLL then maybe you don't need the toolbox and can just use loadlibrary() and talk to the device that way.

Or if there's no software and you just have electrical leads, then you can use a device like from Measurement Computing to connect to the leads and then use the Measurement Computing DLL to sense the voltage on the leads.

See the examples which come with the support package on using it to acquire data.
