Hello,
I have a program I developed on a via machine with the vesafb
framebuffer driver. In tandem with that we've been developing a embedded
version of linux to run off flash based media. So far so good. Just
today I got to the point of testing the directfb app on the device with
the viafb framebuffer instead of the vesafb. Now, the application is
acting up, and I'm wondering if someone could perhaps, via the
description provide some clues as to what has happened.
Basically, I had a main menu, and a secondary screen. On the secondary
screen are some 'animations', to draw them, I would set a clip region,
draw, and flip using NULL.
With vesafb, everything was great, animation speed and all that worked
fine. Now I get the previous screen I guess flipping back and forth,
during the animation. And the animation is WAAAY too fast
(understandable as it is now using hardware memory etc...), but the
flipping effect changes are a little disturbing.
So I'm wondering what I misunderstood about DirectFB that I'm
experiencing these problems. If a code sample is needed, just let me
know. The whole program is just shy of 2000 lines, though it was a
learning experience by trial/error so could use some better design to
simplify, as well the event loop takes up a good chunk of those lines.
