how to drive an powertip 240*128 passive matrix graphic lcd using labview

[nirrvana]

I am a newbie about the usage of labview and i am dealing with a project that has to display an audio  signal on to the lcd display can anyone help me in guiding how to drive the lcd thru labview

Hi There,

I'd really like to help you out here but you really haven't given us enough information to get started.

How do you communicate to the device?  Is is digital direct, serial, USB, etc etc.

What do you hope to display?  How quickly do you need it to be updated.

There are many questions you need to answer before we can start helping you out.  The main one is the interface and the protocol's involved.

Thanks

Actually i am using a Powertip PG 240128 ARS-ATA-A display module i can attach the data sheet, communication is parallel,  and i am not quite sure about the refresh rates as i dont have the manual, even my professor is not sure as the manual was missing  and i couldnt find one in the internet also, thats the problem actually which is not helping me to move an inch, what kind of protocols do we have for this as i have no idea, i am sorry i am totally new i have no clue about the display modules and i am using Blackfin ADSP 533 processor

This is the datasheet of the module i am dealing with

Thanks for helping me out

This may help, it is the data sheet for the T6963 controller chip on your display:

dude

i am looking for a parallel interface from the processor and not the serial link, if anyone can give me some detail about the font size, the controller is specifying it as 5*8 so what does it actually mean

[AdamB]

Hey there,

Firstly my guess is that the font size refers to the width and height of each character. 5 pixels wide and 8 pixels high. (Just a guess)

As for how to communicate to the chip, you need some kind of digital output card/ device connected to the chip.  You will need to use LabVIEW embedded to program the chip (If you are trying to place code directly on the chip).

Try searching NI for "Embedded".  I personally haven't had much experience with that flavour of LabVIEW.  I can't help you at all with the communication to the LCD as you don't know the required order ot pixel output values or speeds or indeed how the processor on the chip interprets its inputs.

You'll need to get onto the manufacturers to find out how to output a total covered screen and how to output a total blank screen.  After that you should be able to work out how to "mix and match" each pixel.

Are you actually going to be using LabVIEW Embedded or a PC of some kind with digital outputs?

Sorry I can't help much more than that.

thanks adam for helping me out

The processor which i am using is a Blackfin 533 and it works at 600 Mhz and the T6963C works at upto 5MHz and the PPI which i am using to connect to the LCD works at half the clock speed of the processor say 300MHz so i am not able to understand how do u actually control the clock to work at 5MHz inorder to make the display work
