Low cost micro for RGB

[Ricko]

Hi,

what are the lowest cost STM32 that support full graphics (static and minimal animation like a progress bar or spin control) with RGB/parallel interface (not DSI nor SPI)?

Is there perhaps a comparison table that addresses such display-related requirements to help select a micro?

If not, any tips, suggestions or guidelines would are much appreciated.

Thank you

I see that it does show tearing effect (when refreshing the screen) and I cannot have that in the product I am designing, the display must refresh immediately and all at once without any tearing. So I was wondering if you are you using the Tearing signal (and despite that it cannot sync fast enough) or if you are not using the Tearing signal at all?

Thank you

There is screen flickering on the camera, but it does not exist in reality. Regarding the screen transitions (information board -> menu), you see the screen where everything is erased first, and then redrawn in real time.

If you implement a buffer and display it on the screen, you won't see this. However, this doesn’t bother me; the main part of the device is in information display mode, and the numbers and images change smoothly without jerking.

If something more powerful but inexpensive is needed, then STM32L431 might be a good choice.
