Hi,I noticed on the GUI Silicon Portfolio that the SPI is used by quite a few micro families for resolutions of up to 480 x 272.I was wondering:1. Do you know if SPI for those micros allows refresh without the tearing effect (i.e. refresh of the whol...

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 requ...

Thank you @AScha.3 the DMA -> SPI timing is very interesting...!(As a side note... "intelligent" displays like the Riverdi are not an option because they are way to expensive. The cheapest one is more expensive than the finished product I am designin...

Thank you @Oleksii 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 u...
