Without knowing what you have used in the DA toolbox and Matlab to read via the sound card, there is not a lot I can suggest.

If you are looking at taking data from a parallel port and doing some "analysis", it would also help to know what "analysis" you are trying to do, or draw.

Hi,
Mr.Dave thank you for your attention to my subject i will tell you i want directly.

I need to know how to write program in matlab to display the ElectroCardioGram (ECG) signal.




I first get the signal from an electronic circuit as analog signal the i converted it to digital data using 8-bit ADC (Analog to Digital Converter) connected to the parallel port.
And all i need is how to display this signal after converting it to digital data and conneting it to LPT parallel port.
I hope you help me.

Thank You.
