Discussion - EVE / Clarification on scrolling
« on: November 01, 2023, 02:27:13 PM »
From what I have gathered scrolling on EVE is achieved by simply redrawing the list at a new position. This works really well when scrolling images and lighter lists.
In our case, we're trying to implement a menu swipe and the screen (list) contains a lot of active elements. Just the SPI transfer of the list takes a bit of time; but this is fine if you're rendering the screen once as it loads.
When it comes to scrolling, however, I think we're limited by the SPI bandwidth and BT817's FIFO and ability to process the list.
Is there a way to tell the chip to "shift" an already loaded list? or a smoother way of accomplishing this?
