command_lcd(0xAE); //DisPlay OFF
tcommand_lcd(0xE2);       //initialize interal function
delay_ms(50);

command_lcd(0xA2); //SET LCD bias(A2-1/9bias; A3-1/7bias)
command_lcd(0xA1); //SET ADC NORMAL(OB-POR seg0-00h) A0: NORMAL  A1: REVERSE
command_lcd(0xC0); //SET COM OUTPUT SCAN DIRECTION(0XXXB-NORMAL)-POR  COM63-->COM0
command_lcd(0xA4); // SET DISPLAY NORMAL (0B-NORMAL)-POR  A4:NORMAL A5:ENTIRE DISPLAY ON
command_lcd(0xA6); //SET NORMAL DISPLAY MODE(0B-NORMAL)  A6:NORMAL  A7:REVERSE
command_lcd(Ratio); //SET INTERNAL REGULATOR RESISTOR RATIO(100B)-POR
command_lcd(0x81); //
command_lcd(Vop); // SET CONTRAST CONTROL REGISTER(00,0000H-11,1111H)
command_lcd(0x2F); //SET POWER CONTROL REGISTER (ALL INTERNAL)
command_lcd(0x40);  //40,3F
               //end of initialzation
command_lcd(0xAF); 这个我是用的好困惑  屏上面什么也没有显示我就只写 1屏初始化  2清屏  3显示字符 4显示字符串然后就是画点再就是一些SPI口的配置好困惑啊度娘上找的七七八八的了  原子哥有什么好方法么

可能不够详细吧  我再贴出代码

以上的这些是我对ST7567的基本操作来的望大家给点意见  解惑一下迷途小书童
