ili9325遇到的问题

今天调试的时候发现，个别的液晶显示屏，程序烧进去之后，刚上电显示的字是反的，复位键之后，显示正常了，而且每次上电都有这个问题，后来发现原因在液晶的初始化程序里：

原来有问题的程序

void init_s95417(void)
{
  LCD_CS_H;
delay(5);
LCD_RST_L;
delay(5);
LCD_RST_H;
        //LCD_RD_H;
LCD_CS_L;
delay(50);//可以适当调整延时，保障稳定显示
        //write_cmd_data(0x0000,0x0001);   //开启内部晶振
write_cmd_data(0x0001,0x0100); //源扫描设置SS=0, 输出的移动方向是从S1到S720
//（源扫描设置SS=1, 输出的移动方向是从S720到S1）
//SM=0，逐行扫描（SM=1，隔行扫描）
write_cmd_data(0x0002,0x0700); //B/C=1、EOR=1：行倒置（B/C=0：帧/场倒置）
write_cmd_data(0x0003,0x1098); //AM=1，地址在水平方向自动加1                                  //1030
//I/D[1:0] = 10：水平垂直方向均增加
        //ORG=1
//BGR=1:采用BGR格式
//TRI=0、DFM=*：8位机、两次数据传送
write_cmd_data(0x0004,0x0000); //比例缩放设置：不缩放

//显示控制
write_cmd_data(0x0008,0x0207); //设置后边沿和前沿
write_cmd_data(0x0009,0x0000);//设置非显示区时间间隔ISC[3:0]
write_cmd_data(0x000A,0x0000); //帧标记功能

write_cmd_data(0x000C,0x0000);//RGB显示接口控制1
write_cmd_data(0x000D,0x0000);//帧标记位置
write_cmd_data(0x000F,0x0000);//RGB显示接口控制2

write_cmd_data(0x0011,0x0007);
write_cmd_data(0x0012,0x0000);
write_cmd_data(0x0013,0x0000);

write_cmd_data(0x002B,0x000D);

write_cmd_data(0x0030,0x0004);
write_cmd_data(0x0031,0x0307);
write_cmd_data(0x0032,0x0002);//0006
write_cmd_data(0x0035,0x0206);
write_cmd_data(0x0036,0x0408);
write_cmd_data(0x0037,0x0507);
write_cmd_data(0x0038,0x0204);//0200

write_cmd_data(0x0061,0x0001);

//
