I play around with the tower LCD and MCF52259, i take a deep look inside how egui work, and i used it to display picture stored in a SD card, to do that i read a block a 4ko of data from SD card and i send it to LCD via Egui pixel by pixel, this is not very fast and when the picture is displayed they aperar "gradually" from bottom up.

What i want to know it's if  possible from egui to send data to LCD and when upload is finish to inform the screen that i could refresh the picture, because actually the picture is refresh each time i send a pixel.
