抄代码，上电，观察，如此反复
虽是初级阶段，好歹有效，就是效率太低

jlink，430jtag……在这里不如一块万用表

还是不行，参照楼上的电路图，加了两个电阻R22=100K，R23=100K，C11 C12 C13 C15 用的是无极性的0603贴片0.1uF电容，C7 C8 C9 C10 C15用的是0603贴片1uF电容，不知电容是不是一定要有极性？
D1~D5全部接地。

会用这个屏的朋友指点一下，谢谢！
以下是本人调试的代码：

1. M_LCD_RES_OUT_0();     //?′??3?ê??ˉ
   
2. fn_Delay_us(50000);
   
3. fn_Delay_us(50000);
   
4. M_LCD_RES_OUT_1();
   
5. fn_Delay_us(50000);
   
6. fn_Delay_us(50000);
   
7. fn_Write_Command(0xae);//Power save mode On
   
8. fn_Write_Command(0xa2);//LCD bias select 1/9
   
9. fn_Write_Command(0xa0);//ADC select éè??áD??ê?·??ò
   
10. fn_Write_Command(0xc0);//Common direction select éè??DD??ê?·??ò
    
11. fn_Write_Command(0x81);//EVR mode set Electronic volume mode set
    
12. fn_Write_Command(0x21);//EVR mode set ??±è?è  Electronic volume register set
    
13. fn_Write_Command(0xa5);//Power save mode Off
    
14. fn_Delay_us(50000);
