Using RA6963 128x240 LCD and r8g2lib only displaying fully white on LCD

[ethanreeve04]

I am using a RA6969 128x240LCD with r8g2lib and the LCD only displays white screen.

My Code:

#include <Arduino.h>
#include <U8g2lib.h>
#include <SPI.h>
#include <Wire.h>

U8G2_T6963_240X128_1_8080 u8g2(0,0,1,2,3,4,5,6,7,13,11,10,9);

void setup(void) {
 u8g2.begin();
}

void loop(void) {
 u8g2.firstPage();
 do {
   u8g2.setFont(u8g2_font_ncenB14_tr);
   u8g2.drawStr(0,15,"Hello World!");
 } while ( u8g2.nextPage() );
 delay(1000);
}

Please post your schematic so we can see what model of Arduino you are using and how it is wired to the display.
