okay im at wits end, after going over this 500 times the last couple days i still cant get this lcd to work...
info
this is the lcd i bought based off SSD1963 driver
http://www.ebay.ca/itm/5-5-0-inch-TFT-LCD-module-Font-IC-800x480-SSD1963-arduino-DUE-MEGA2560-3-5-7-3-/111005370687?pt=LH_DefaultDomain_0&hash=item19d86f893f
I have been unable to find any atmega libraries for the SSD1963 so aftergetting copies from the arduinos, pic, and the SSD1963 datasheet and what not for reference's ive done my own library.
So at the end of my init routine it should turn the screen red, and all i get from my lcd is a white screen, so it looks like its turning on but thats about it.....Anybody able to help me figure whats wrong
