Interfacing PIC18F4550 with LabVIEW

Hi all
I am working on PIC18F4550 and LabVIEW.
I want to send an analog data through ADC of PIC to LabVIEW waveform chart using USB interface.

The PIC has a HID bootloader.The program I have burned in PIC is of MCHPUSB generic driver class PICDEM FS USB type.

Initially I chosen to simulate the analog input, as in, I have created an array of elements PIC memory.I send this data to LabVIEW using USB.

Problem is I get the data displayed. but not in sequential form, like that stored in PIC.
The data acquired by LabVIEW is quite random.

In short,the values that are received, or rather displayed, in Labview are within the subset of array defined by me.But they are not displayed in correct order.

What can be the problem?
Any delays should I add on either side?If so,then how much exactly?

Hi vinay21,
I think it will be really helpful if you are using another application, to check weather data is received properly. Better try "USB HID" terminal provided in MikroC compiler. with this tool you may send and receive data to USB.

Hope this helps...
