Hi Ivan,

First thanks for providing this awesome project for driving these types of displays.
I've successfully used the examples with an EL display aswell, the Planar EL320.240.36 specifically.

Here I used the text example to make a simple serial terminal that works perfectly.

After some struggles with WinUSB and compiling the source I also got the usb bridge to work, but have 1 small issue with it that I cant pinpoint where the issue is. THe issue is that the image is displayed but with some kind of noise or corruption that the other examples dont have.

I have checked the connections and those are correct, have tweaked the timings where I could understand how but it made not much difference.
Do you have any idea where to look ?

I've found the culprit, the display doenst like dithering, have sort of workaround that in the 'driver' and looks good(ish) now.
Have to look if I can disable that completly so some pixels dont look out of place on certain places
