Hello,
I'm new to emwin. I read the user manual carefully and were able to get emwin to work with LPC2478 which is a legacy device maximum frequency is 72Mhz.
What I wanted to do is creating a sliding window with some icons on it. When someone swap on lcd, it should go to the hidden part of the window. The transistion should be smooth as in mobile phones. I was able to do that using emWin but the transition is not smooth. I think that is due to the LOW operating frequency. I think cpu cannot render the image before LCD update rate. When I increase the lcd frequency, display shows some garbage data when I touch the screen. When no touch on screen the screen shows what it has to show without any issue. ( I have coded to invalidate window when the screen is touched ).I have enabled multi buffering. So I decrease the lcd frequency. Now it does not show garbage values but the animation is not smooth. It would be great if some expert can explain the real issue.
My other question is will there be any plus point if I use memory devices with such low operating frequency cpu ?. because I cannot render the image before lcd refresh.
