Hi

Is it with the code or the hardware interface you are stuck with?

Do you work with assembly code for interface ?

if you work in C you can use sprintf() in <stdio.h> to convert numeric data to a text string which can then be written to an LCD display, e.g.

    char text[20]={0};
   sprintf(text,"%s board V%d.%d", SYSTEM, VERSION, SUBVERSION);									
   lcdStringAtCursor(text);

I had seen the slow response and low quality in display color 1024 x 480 pixels, so try make clear with you code in some project .

Sometime , we work with low quality eqipment , the good mathematical model must be use , PCA , neural network , Fuzzy Logic , Genetics Algorithm ... etc.

Did you connect a 1k resistor at the terminal of each row?
