[svijay]

how to acquire  and send anolog or digital input through the usb and other ports in my laptop without using any daq?

i am using dell inspiron 14R hrthere are many ports in  my laptop .... is there any way to access datas through those ports.

No. The USB interface was not designed to do analog data acquisition. It's not a scope. It's not a multimeter. It's an interface designed to communicate with devices. You might be able to do digital I/O by controlling the lines at a raw level, but the amount of time you spend figuring it out is better spent buying a low-cost digital I/O device.

My computer has a lot of ports on it too. That doesn't mean I try to plug a blender into it so I can cook.

If you have a printer port, you can send receive digital data. That's it.

Vijay,

I am not sure what you want to do with USB port, but here is a link to the parallel port utilisation:

blenders no, toasters yes.

RE: data acq without DAQ

YOu can cheat with some of the i/o but a small error on yur part and you are replacing the mother board. A cheap USB DAQ device is a better route.
