Anyone have information on SP14q006-zza

[Corbet]

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.

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.

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

Is it possible to use a really slow clock to be sure everything is working right? I guess what I'm asking is will all the pixels stay where they are set while the clock is running? What will make it reset to a default state? If I stop sending the clock will the display reset?

What will make it reset to a default state?

I don't see a reset pin, so you will probably need to turn the display off and on.

If I stop sending the clock will the display reset?

On the displays that I have used before the pixels don't get reset if I stop sending signals to the display. I don't know what would be the case with your display. My guess is that the screen will not reset.
