Extremely smooth OLED scrolling display

Matrix refresh based on cache, the measured average refresh time is 2.6ms, the limit is greater than 300FPS, and the sliding display is very smooth

Demonstration effect

The effect is indeed good, but animation effects on small OLED screens are actually not very useful.

Looks OK

The video function in the editor can be displayed by directly putting the corresponding link. I've posted it for you

Thanks, the video is quite large so I will just post the link

Thanks for the suggestion. The purpose is to optimize the underlying refresh mechanism. It seems to work well now, which will facilitate some interface switching applications in the future.

Not bad, is it using SPI? It's almost the same if it's over 60Hz. The effect seen at 300Hz and 60Hz should be similar.

Yes, increasing the maximum refresh rate is to buy time for UI drawing.

It's a bit like the lock screen animation in XP system.

Which microcontroller can achieve this effect?

Indeed, the screen refresh speed is very important, as it allows other programs more time to run!

Currently, we use double the temporary cache refresh, and we can further reduce the memory usage later.

fine!

Sure, sure.

Awesome, it works pretty smoothly, and there are optimization goals. Come on.

It is still in the optimization and testing stage, and the real application has not been written yet. The original intention of this board design is a downloader. It can be run through the USB or DAP interface to download firmware using LUA scripts, or directly used as a DAP emulator. The optimization of the display is almost done. The next step is the integrated design of the downloader function.

It looks like the effect is indeed refreshing very smoothly.

It looks very good. The current display direction has both high refresh and low refresh requirements to achieve applications in different scenarios. Thumbs up

Thank you for your support. I forgot to turn on 60Hz anti-flicker when shooting with my phone. The actual effect should be better.
