Posted on May 29, 2016 at 12:55Hi,
I'm using STM32F429 with tft of 640X480 with touch.
I want to simulate the effect of screen swipe – as in Smartphone: When the user swipe it's finger the screen is moving to that direction and another screen is entering.
I know how to do that using 3 screens:
1 for the current display
1 for the exist screen
1 for the new screen
I need to copy every step part from screen 2 & 3 to screen 1 – this is the old way solution…
When I read about the STM32F429 it seems that it has many TFT option. (Layers , DMA2D..)
Is there any other SIMPLE option to do this swipe simulation without copy every time parts of the screen? Maybe there is a short way using the layers or just the registers that telling the TFT where to start.
I Assume that the easiest way is if I could have the 2 screen in memory – and by only manipulate the screen pointer (start of frame) I can show each part of the 2 screens?
I Also watch some demo (Like a Pac-Man game) that the display of the STM32F429 show only part of a big picture – But I can't get that sample code to understand the manipulation…
Any suggestions?
