Share your working BASCOM-AVR code here : Fast library for SSD1963 LCD : REPLY

Thank you Mrshilov and everyone else for sharing your hard work! This library is great, much faster than previous examples. I am running an [url=http://www.buydisplay.com/default/7-tft-screen-touch-lcd-display-module-w-ssd1963-controller-board-mcu.html]ER-TFTM070-4[/url] display on ATMega645A @ 16MHz. I swapped Mrshilov's initialization values for my own (based on the sample code provided by the manufacturer) and it works well with one problem: Display is upside down and color is in BGR mode, but control register [b:2fc0418f06]Set Address Mode 36h[/b:2fc0418f06] has no effect on the screen! In my old routine I can change [b:2fc0418f06]Set Address Mode 36h[/b:2fc0418f06] to flip display in any orientation and change the color mode. With Mrshilov's routine, no change! Only difference I can tell is Mrshilov uses submode=new while my working routine uses old submode. I could fix this by flipping the screen around and changing the color constants to BGR, but that feels like a hack job :P. Does anyone have some insight? Thanks again for sharing.
