Imperfect animation with TouchGSX
Hello,
i'm trying to execute a simple animation with TouchGFX. I'm using the Texture Mapper image, and i want to reproduce a spin of that image. As you can see in this video it was succesfully done. However, there is an extra random flashing.
I'm using the internal FLASH memory, for now. I think the problem comes from the RAM or from DMA. The latter was configured as Register to Memory, and i enables the interrupt.
While the RAM is a 16 bit (maybe too low?).
The code to create the animation is
screenViewBase.cpp

screenViewBase::screenViewBase()
{
box1.setPosition(0, 0, 720, 720);
box1.setColor(touchgfx::Color::getColorFrom24BitRGB(0, 0, 0));
textureMapper1.setXY(180, 180);
textureMapper1.setBitmap(touchgfx::Bitmap(BITMAP_BACK2_ID));
textureMapper1.setWidth(360);
textureMapper1.setHeight(360);
textureMapper1.setBitmapPosition(0.000f, 0.000f);
textureMapper1.setScale(1.000f);
textureMapper1.setCameraDistance(1000.000f);
textureMapper1.setOrigo(180.000f, 180.000f, 1000.000f);
textureMapper1.setCamera(180.000f, 180.000f);
textureMapper1.updateAngles(0.000f, 0.000f, 0.000f);
textureMapper1.setRenderingAlgorithm(touchgfx::TextureMapper::NEAREST_NEIGHBOR);
add(box1);
add(textureMapper1);
}

}I hope you can help me.
