SainSmart Mega 2560 + TFT_320QVT

I bought this:

To get it working, all I needed to do was download the UTFT library from

http://www.henningkarlsen.com/electronics/library.php?id=51

Then go through and add:

const in front of each font definition in DefaultFonts.c

~/sketchbook/libraries$ diff -t UTFT UTFT.orig
diff -t UTFT/DefaultFonts.c UTFT.orig/DefaultFonts.c
21c21
< fontdatatype SmallFont[1144] PROGMEM={         
---
> const fontdatatype SmallFont[1144] PROGMEM={         
125c125
< fontdatatype BigFont[3044] PROGMEM={
---
> const fontdatatype BigFont[3044] PROGMEM={
234c234
< fontdatatype SevenSegNumFont[2004] PROGMEM={
---
> const fontdatatype SevenSegNumFont[2004] PROGMEM={

In the demo file, comment out the myGLCD line and replace it with this one:

// For Mega 2560
UTFT myGLCD(GEEE32,38,39,40,41);

// or

UTFT myGLCD(ITDB32S,38,39,40,41);

For the TFT_320QVT you of course want the 320x240 demos.
