I want to interface  NHD-2.7-12864WDW3 OLED display having SSD1322 controller with STM32F407G-DISC1.

I am doing 3 wire SPI Communication, So i have connected all 20 PINS as follows:

Pin1 ---> GND

Pin2 ---> 3V

Pin3 ---> NC (No connection)

Pin4 ---> PD9 (DC; GPIO_Output, assigned by cubeide) 

Pin5 ---> GND

Pin6 ---> GND

Pin7 ---> PA5 (SCLK; SPI1_SCK, assigned by coubide)

Pin8 ---> PA7 (SDIN; SPI1_MOSI, assigned by coubide)

Pin9 ---> NC (No connection)

Pin10 ---> GND

Pin11 ---> GND

Pin12 ---> GND

Pin13 ---> GND

Pin14 ---> GND

Pin15 ---> NC (No connection)

Pin16 ---> PB12 (RES; GPIO_Output, assigned by cubeide) 

Pin17 ---> PB13 (CS; GPIO_Output, assigned by cubeide) 

Pin18 ---> PB14 (SHDN; GPIO_Output, assigned by cubeide) 

Pin19 ---> PB15 (BS1; GPIO_Output, assigned by cubeide) 

Pin20 ---> PD8 (BS0; GPIO_Output, assigned by cubeide) 

After writing the sample code also the OLED display is still dead.
What is the solution? What can i do next?
