Hi,
I need to design a PCI interface card using microcontroller. Is that possible? Or I should go for microprocessor.
Thanks praveen
PCI, of course, has its own speed limitations!
You still haven't said - despite being asked at least three times - what your actual throughput requirement is!
What, exactly, was the limitation you experienced with the serial port?
Was it a real serial port - ie, with real UARTs, etc? If so, what baud rate were you using?
"What will be the best option for me to interface these sensors to PC?"
It is still impossible to say - because you have still failed to provide any details!
"What is the advantage of using USB compared to PCI?"
It will be orders of magnitude simpler!
If a single USB (or serial) link can't cope with all your data, then you can easily just use multiple USB links...
FTDI do some pretty neat cables that go straight from USB to 5V or 3.3V logic on loose wires or pin headers: " href= "http://apple.clickandbuild.com/cnb/shop/ftdichip?productID=53&op=catalogue-product_info-null&prodCategoryID=47"> apple.clickandbuild.com/.../ftdichip
So you can easily convert a microcontroller's standard UART to USB with no design effort and very little cost!
Or just choose a microcontroller with built-in USB...
Another advantage of USB, of course, is that you can use it on any computer - not just one with a free PCI slot.
eg, a laptop...
Thanks
Actually I have given a project of 6 channel counter card with PCI Interface.
The maximum frequency output from the sensor is 20Khz. This my first project in PCI based systems and I want to familiarise with it. Where will I get sufficient information regarding?
I came across the Quicklogic IC(QL 5130) which can be interfaced with 8051. I think it is a simpler way to do this project.
