18 BIT ADC PARALLEL DATA CAPTURE With data ready signal using NI DAQMX and PCI6534

[SIVA_M]

Hi,

I want to capture  N (65536  ETC)  18 bit digital data using PCI6534 and NI DAQMX Software. Acquire the data once on every
rising edge of data ready signal. When there is no data ready signal, nothing should be the acquired.

Also I want to start capture data when data matches a particular parallel data pattern. Please post any example VI.

Hi, 

I would request you to refer the given below links. They would take you to some example VI's that almost functions in the manner you specified in your query.

Sagar,

Thank you for the details. Now I am able to develop my code. Please find the attched vi for the details. Could you review it once ?

I want to capture 18 bit data,So  I am using port0_32 as my input port.

For individual ports P0.7 is MSB and P0.0 is LSB. Which is MSB and LSB when I select all ports as input ? I am assuming P3.7 is MSB  and P0.0 is LSB.

I am using PFI2(or PIN 2) as external sample clock. Is this correct?

Is my code is fine to collect 18 BIT ADC DATA using external data latch signal ?

Thanks,

Siva
