Using adi_Nl6448bc33_open

[Seoul]

Hi everyone!

   I need your help. I have ADSP BF 537 EZ kit lite. and AV EZ extender board. I want to connect A micron camera captured picutre then display on the TFT LCD as detail: NEC 10" NL6448BC33. I have seen Vi for this LCD in the directiontory: C:/program files/ National Instruments/labview 8.5/vi.lib/embedded/vdk/device/NL64448BC33.

   But when i open this Vis  that it include error : "The function name specified for this node cannot be found in the library. Right-click the Call Library Function node and select Configure, then choose the correct function name."

  Please tell me how i can fix this error or suggest an idea for me how to program for displaying that LCD?

  here is NL6448BC33 from Labview embedded module

 Thanks in advanced!

I have one more thing that we have NL6448BC33_DisplayFrame function in the DeviceStub.dll Library. How i can you this function and how about it's parameters.

I have bought NEC NL6448BC33 LCD and AV AZ extender board. then i want to use combination these devices in my project.

Any body can help me solve this problem.

Thanks so much!

Hi Seoul,

I am gathering enough hardware needed to run this example.  I will shortly post my results.

Hi Seoul,

I have investigated the VI that you mentioned (C:/program files/ National Instruments/labview 8.5/vi.lib/embedded/vdk/device/NL6448BC33/BF NL6448BC33 Open.vi).
It appears that NI is possibly thinking of writing an example for your device that would use this VI, but it has not been finished.  This VI is a callback VI.

If you open the AD1836 Graph example and double click BF AD1836 Open.vi in the block diagram, it references a callback VI, which uses the same dll that you were looking at (DeviceStub.dll).
Please note that the BF NL6448BC33 Open.vi is on no palette in LabVIEW.

In order to use your hardware, you will probably have to create VIs that reference the Parallel Peripheral Interface (PPI).
In order to get started with this, I would view these articles as well as pay attention to an already existing example.
Integrating Custom Hardware in LabVIEW (Blackfin)
PPI VIs (Blackfin)
Using the Device VIs (Blackfin)
BF EPPI Control (Blackfin)

I hope this helps,

Hi Kevin. S!

Thank you so much for your reply! I already study recomendation as your mentioned. Bit it did not help me to solve my problem!

I  have been used ADSP BF537 AZ kit lite. so i can not use EPPI Vis. these VIs just use only for ADSP 548.

i have read device driver documention for Nl6448BC33_54. and try open this device in the Labview embedded but still not successful.

can you help me how to open a TFT LCD like this one
