FM6373 - 128x64 Panel - Research - Waveforms captured

I was hoping if we could leave this thread open for research on this panel.

I've obtained logic captures of this device by using an MSD300 sender card and MRV412 receiver card.
I power on the receiver card and capture the start up to displaying red , green and blue.

I've attached a file with all the captures.

You just need to download the KingstVIS software to open the kvdat files. and you can scroll through the waveform captures and see the data.

You can easily see the start of each frame repeated every 16ms 60hz. It seems to have the same 5 blocks and then the colour data of the frame.

Also the settings of my Nova LCT receiver card config for the FM6373

If there is anything else that may be useful on other channels on the device let me know.

@kingdo9
Thank you very much for the information.
Judging by the diagrams, the protocol of the FM6373 driver is very similar to of the DP3264 one, which I have. But I have not managed to write code for it yet
What are your successes? Have you tried writing programs to work with this or other PWM drivers? It would be interesting to see if this code is available, for example, on GitHub.

Thanks again for your work, but I hope you understand that the chances of writing code for the driver without such a panel for testing are quite small.

If there is anything else that may be useful on other channels on the device let me know.

Yes, there is. It could be very helpful to get an example of any "color diagrams" (such of red.kvdat , red2... , green. or blue. ) with A & B channels added.

Sure I can get them, I should also be getting a better logic analyzer soon also.

Did you check the archive file I linked to of my captures?
you can also open the captures using KingstVIS which is free to download.

The coding is a bit beyond me but, I've been feeding the information and source into Gemini 2.5 pro, and its very good what it can interpret once you feed it all the details. I may experiment with that further.

Of course, I downloaded your archive and looked through the diagrams with interest. Thank you again.
Your logic analyzer produces good diagrams. If in some case you do not have enough analyzer frequency - you can try to set a lower frequency in the sender card interface.

However, please note that it is important to record all related diagrams on the same panel settings. If you record a new diagram, as I asked you - please set all panel settings the same as when recording those diagrams that you sent

WBR, Dmitry

Here is rgb with AB channels.
I have to capture at 40mhz to get reliable data, so only 6 channels at a time. Hopefully my new analyzer will be able to do all of them at the same time.

Thank you.
I can analyze it at the evening (GMT +3)

Sorry, I didn't say about the channels. I need A &B, CLK, LAT and OE at least. The RGB channels are not important, choose any that you like.
What the channels you selected for capture?

Yup, A, B, R0, CLK, LAT, OE

[board707]

Excellent!
Thank you very much!

[kingdo9]

Just some further KingST Vis captures. New card capturing all channels at 50mhz.
You can disable any channels you want from the program to make specific ones larger in size.

Red, Green, Blue, White, Gradient black to white and a from power on to red test screen capture.

[board707]

Thank you very much

[kingdo9]

Thank you very much

If you have somewhere to receive mail. I'm happy to send you one of these displays for free. I have a few.
Not expecting anything to be done with it, just you have one if you do decide to look at this particular display.

No expectations I just have a few of these lying around, probably be more use to you.

@kingdo9
Where are you from?

[board707]

I can put an Email here

Thank you, I already have your email, we corresponded at the beginning of May. :)

Hi. I am very interested in this topic, because I am currently working on the ICN1065 chip. As usual, there is zero information. That's why I was interested in the CS (c#) source code that was in your download (Nova.LCT.GigabitSystem.ChipFM6373). Do you have the source code for Nova.LCT.GigabitSystem?ChipICND1065.dll ?
The NovaLCT has a dll (Nova.LCT.GigabitSystem.ChipICND1065.dll), but I don't want to get too involved in it.

Some configs you might be interested in for ICND1065 , Do these have any useful details in them?

Thank you very much! I will investigate.
