How do I use GD with a 800x480 display?
If you're using the Gameduino 3 7" model, this is done for you by the Gameduino 3's configuration flash.
If you're using another screen the setup procedure must be done explicitly.
After calling GD.begin() you can set the scanout registers for 800x480 like this:
GD.wr16(REG_HCYCLE, 928);
GD.wr16(REG_HOFFSET, 88);
GD.wr16(REG_HSIZE, 800);
GD.wr16(REG_HSYNC0, 0);
GD.wr16(REG_HSYNC1, 48);
GD.wr16(REG_VCYCLE, 525);
GD.wr16(REG_VOFFSET, 32);
GD.wr16(REG_VSIZE, 480);
GD.wr16(REG_VSYNC0, 0);
GD.wr16(REG_VSYNC1, 3);
GD.wr16(REG_CSPREAD, 1);
GD.wr16(REG_DITHER, 1);
GD.wr16(REG_PCLK_POL, 0);
GD.wr16(REG_PCLK, 4);
How do I use GD with a 320x480 display?
There is a writeup here: http://excamera.com/sphinx/article-ili9488.html
How do I use GD with the Sunflower Shield?
At the start of GD2.cpp change BOARD and CALIBRATION:
#define BOARD BOARD_SUNFLOWER // board, from above
#define STORAGE 1 // Want SD storage?
#define CALIBRATION 0 // Want touchscreen calibration?
How do I change the select pin assignments?
To change the GPU select from pin 8, modify #define CS at the start of transports/wiring.h
To change microSD select from pin 9, modify #define SD_PIN at the start of GD2.cpp
How do you run in portrait mode?
After calling GD.begin() set the orientation like this::
GD.cmd_setrotate(2);
to enter portrait mode. The argument controls orientation, 0 and 1 are landscape. 2 and 3 are portrait.
