Programming on Labview to DDC11xEVM-PDK

Other Parts Discussed in Thread: DDC11XEVM-PDK, DDC114

I am currently working with the DDC11xEVM-PDK using Labview code in
(VIs_to_DLL.zip) and DLL functions of (USB_IO_for VB6.dll), to communicate with the DDC11x Evaluation Module. I have been able to both send and retrieve data from
the module. Using the proper VIs posted on this forum and setting some configurations i am receiving a 1-D array of 512 samples, and each sample has 8 bits.
The first problems is that even changing the light intensity in order to go from 0% to 100% of the full scale, I still have some positions of the array displaying zeros instead of some different values.The second is that i was expecting to receive at least 16 bits per sample considering the received information samples from the DDC114 A/D Converter.


Thanks in advance for your help!

    Pablo, 

    Are you able to measure the correct input levels or receive the right amount of bits using the DDC11X EVM software provided? If so, you may need to debug your labview code.

    Yes using the official software provided it works, and using the VIs from this forum I am able to send some information to the EVModule, including the "take data" operation Op.codes. But I still can not identify what kind of information is the EVModule sending after the "take data" operation.


    Thanks
