I'm "painting" to the display by writing directly to the two frame buffers I have (g_display_fb_background[0] and/or g_display_fb_background[1]) but I'm having problems sometimes. I have ThreadX so I think it's a timing or exclusion problem. Please, what are the precautions or conditions I have to fullfill in order to be able to write directly to the frame buffers when the display driver is running. Or there is another better way to paint directly to the screen?
Thank you in advance.
