Anyone have information on SP14q006-zza

[Corbet]

Ha it's on there, I can't believe I missed it the first time. Thanks
Now anyone have any idea how to communicate to it?

Try brainwave and see if this works, case not you may give a call to E.T. or Alf, they should know how to

This would help if we knew the controller IC on it.. nothing the datasheet seems to mentions.

At your sarcastic request I popped it apart and it has 2 ICs on it, one has 73099hed on it and it is a 16 pin IC. The other is a 14 pin IC with la6324n and a 5x7 on it. Hope this helps.

yikes, not much good info on that, the only thing I found was the La6324... op-amp...not really usefull. It reminds me a batch of LCD i bought here a while back...recycle bin they went... Hitachi are REALLY good to build things...without decent documentation...

Will send an email to my Nerdz, maybe they could find something.

Corbet,

Reviewing the datasheet it doesn't look like you have to initialize the display like it is done with other GLCD displays. I think that everything that you need is in the datasheet. Look at "8. Interface Timming Chart" it tells you what you need to do to "fill" the 320x240 screen with your data. Also, the pin connections and the power setup are described in the datasheet.

Hey thanks, I have a mild understanding of how it works sorta but there are a lot of signals flying around. D0-D3 tell the display which Ys to light for the current X at every CL2 cycle but how does it know which X it is on? The timing chart is a little confusing there. What does the FLM do? I assume CL1 and CL2 are clock pulses and it says CL1 is roughly 20 MHz (52.1-59.5 us) .

Does anyone have any experience, code, or schematics that might help me start?

That's correct.

but how does it know which X it is on? The timing chart is a little confusing there. What does the FLM do?

It starts from X1 all the way to X240. Looking at the datasheet FLM marks the beginning of the whole screen cycle. It tells the display where X1 is at.

I assume CL1 and CL2 are clock pulses and it says CL1 is roughly 20 MHz (52.1-59.5 us)

You don't really need a precise "clock pulse" with a fixed frequency. Using the PBP commands HIGH and LOW in a digital pin will be enough. The frequency constraint is set to avoid flicker and rippling on the display.

Does anyone have any experience, code, or schematics that might help me start?

Sorry, I have never used this GLCD display, so I don't have any code for it.
