Hello, i have a problem with display by mcufriend like this, but from dxcom.

I connect this screen(look down side pins on photo) to Arduino nano V3.0. I used Adafruit-GFX-Library and connection pins:

LCD_RST - A4/RESET(arduino) use 3.3V
LCD_CS - A3(arduino) use 3.3V
LCD_RS - A2(arduino, not connect, coze it touchscreen) use 3.3V
LCD_WR - A1(arduino, not connect, coze it touchscreen) use 3.3V
LCD_RD - A0(arduino) use 3.3V

GND - GND(arduino)

5V - 5V(arduino)
3.3V - 3.3V(arduino)

All what i see: white screen. what the hell am i doing wrong? I can not understand, please say me what i need to do.

Well, the other markings on the digital pins might help. It appears to have a 8 bit parallel interface. Try modifying the LiquidCrystal examples that come with the IDE.
EDIT Definitely not usable with LiquidCrystal.

You can use the 4 high bits-D4,D5,D6,D7.
