Hello,
In our project we use GUI_BMP_SerializeEx to take screenshots of what is on our 320x240 LCD. The bitmap files generated by this function look nearly perfect except for a few pixels (20-30 on average) that are incorrect (wrong color).
The location of the incorrect pixels appears to be mostly random, but they usually appear near drawn objects/text and don't appear in areas where it's just back the black background.
When we look at the LCD, none of the pixels are wrong, it's only in the generated bitmap "screenshot" files.
Does anyone know if there's any reason to suspect a software issue? Or would this more likely be a hardware issue?
Thanks!
