can we use a non NI device like a USB microcontroller to communicate with labview for data logging?

[JK007]

i want to log data frm a USB controller like PIC18F series..can it be done using labview? i am new to usb controlling...dont know exactly how to use the interrupts sequence...can anyone provide with a basic example???? Thanks in advance

most usb based controllers can be communicated with via the serial port.

so on the controller you need an example, in LabVIEW you use the basic serial read write example.

actually i hav a project in which i have to log the data through USB....can it be done?

[Albert.Geven]

who said that usb could not emulate a serial port?

i want to transfer data through the controller to the PC....only hav to wake interrupt the pc to take the data and not the other way around

I don't think you understand what Albert is saying. If you choose, you can use a USB driver for your device that makes the USB connection a virtual serial port. The LabVIEW programming becomes simpler. If you stick with a USB RAW protocol, you have a bit more difficult time. Iwould suggest you read the series of Nuggets written by Intaris.

thanks.. this might help!!
