1. In file
remove/comment lines 160 and 161: u8g_dev_ssd1322_nhd31oled_gr.c
  U8G_ESC_ADR(0),                   /* instruction mode */
  0x0af,                                 /* display on */

2. in your code, execute the picture loop without body (this will clear the 
screen),
3. execute the sleep off command (which will turn on the display)
