Hi,
I need to design a PCI interface card using microcontroller. Is that possible? Or I should go for microprocessor.
Thanks praveen
"[...] so I landed in PCI."
Still no information why you think PCI is your only (or prefered) choice.
"What will be the best option for me to interface these sensors to PC?"
Still no estimate about what bandwidth you need, in which case people are unable to make suggestions about different interfaces (RS232 at a higher baudrate than you have currently tested, USB, FireWire, Ethernet, ...).
And you haven't mentioned anything about latency requirements.
"What is the advantage of using USB compared to PCI?"
I thought that was obvious.
What is the advantage of being able to upgrade your computer without having to open it?
What is the advantage of not having to cater for both PCI and PCI-E?
What is the advantage of being able to use existing USB drivers compared to creating own PCI drivers or buy a DDK with skelleton drivers to rewrite?
What is the advantage of using an interface that a large number of microcontrollers has built-in?
What is the advantage of using an interface where your data collector can be several meters away from the computer, allowing the data to be sent in using a nice, cheap, standard data cable?
What is the advantage of being able to hot-plug the device?
What is the advantage of being able to support Linux and maybe Mac at a limited cost?
What is the advantage of being able to plug in one more device (still hot-plug) if you need more inputs than the first device supports, without noticing that there are no more slots left on the motherboard?
What is the advantage of being able to support a laptop?
What is the advantage of being able to bring a device in your pocket/bag and connect to a customer's computer?
Need I go on?
