whether have use SPI drive 7 pin oled(0.96) example

[adminSxs]

i try to use SPI impl dervice oled ,but fail

	OLED_WriteCommand(0xDB);
	OLED_WriteCommand(0x30);

	OLED_WriteCommand(0xA4);

	OLED_WriteCommand(0x8D);	
	OLED_WriteCommand(0x14);

	OLED_WriteCommand(0xAF);
	OLED_Clear();				
}

above is c code
