RA8875, trying to write on both layer 1 and 2

by abreton96 on Mon Mar 12, 2018 10:57 am

Hi everyone!
I have a 5" 800x 480 screen controled by the RA8875.
I saw on the datasheet that i can't write on the second layer if the resolution of the screen is over 480x400 (REG[41]) and the color depth is over 8bpp. Is there a way to write on layer 2 without minimizing the color depth?
I also want to ask if there is a fast way to draw picture on the LCD. I'm currently drawing pixel by pixel and it takes like a minute to draw a big picture.
Thank you for your response!
