Dear all,

I am fairly new to the LCD controller of LPC1788.
I have a 7" (800*480) TFT LCD and I wan to drive it using the LPC1788 MCU. I am using the SWIM graphics library developed by NXP to build a user interface which includes buttons, Text boxes, labels, etc. The problem I am having is that when you click a button or do things of that kind and the LCD want to upload a new frame, it flickers. I have tried to use double buffering but it did not work out (maybe I am using it wrong).

If you have any experiences in this field (preventing flickering) or any code sample I would really appreciate if you helped me.
