MTK LCD 驱动

zhoulianghao166 2009-03-13 06:04:03
有哪位大虾能告诉我下面这段驱动初始化程序代码有哪位大虾能告诉我下面这段驱动初始化程序代码都做实现了什么，
怎样区分语句是命令还是参数设置???

void LCD_Init_S6B33BF(kal_uint32 bkground, void **buf_addr)
{
volatile kal_uint32 i;
kal_uint16 background = (kal_uint16)bkground;
kal_uint16 read_data;

CLEAR_LCD_CTRL_RESET_PIN; //REG_LCD_CTRL = 0
Delayms(50);
SET_LCD_CTRL_RESET_PIN; //REG_LCD_CTRL = 1
Delayms(50);
LCD_MainLCD_CtrlWrite(0x2c);
Delayms(20);
LCD_MainLCD_CtrlWrite(0xEB);
Delayms(20);
LCD_MainLCD_CtrlWrite(0x02);
LCD_MainLCD_CtrlWrite(0x01);
Delayms(20);

LCD_MainLCD_CtrlWrite(0x20);
LCD_MainLCD_CtrlWrite(0x0a);
Delayms(20);
LCD_MainLCD_CtrlWrite(0x26);

LCD_MainLCD_CtrlWrite(0x45);
LCD_MainLCD_CtrlWrite(0x00);
LCD_MainLCD_CtrlWrite(0x53);
LCD_MainLCD_CtrlWrite(0x00);
................
................
LCD_MainLCD_CtrlWrite(0x9F);
LCD_MainLCD_CtrlWrite(0x43);
LCD_MainLCD_CtrlWrite(0x04);
LCD_MainLCD_CtrlWrite(0x83);
LCD_MainLCD_CtrlWrite(0x55);
LCD_MainLCD_CtrlWrite(0x01);
LCD_MainLCD_CtrlWrite(0x5A);
LCD_MainLCD_CtrlWrite(0x00);
LCD_MainLCD_CtrlWrite(0x51);

LCD_ClearAll_S6B33BF(0xffff);
}

我是搞MTK软件的，但因需要得调驱动，
搞不懂上面的括号里面的是命令还是参数
感觉怎么都是命令 但参数不知道参数是这么设置的
有哪位高手指点一下

感觉不尽

LCD_MainLCD_CtrlWrite(0x2c);

命令和参数其实是一回事,如此行语句,就是主控端(基带)往外设(LCD)发送外(LCD)设要求的参数;对基带来说是在发送命令,对LCD来说,是获得合适的参数.

是命令，不同的参数代表不同命令

LCD_MainLCD_CtrlWrite函数是向对应的lcd的io接口写值
来进行驱动程序的初始化，lz可以参考LCD手册
下面是个c语言版S6B33BF的驱动，里面有英文注释，参考一下
