[mw_shl_code=c,true]驱动为RM68042，想要整屏显示红色，现在只有背光可以，没有其他现象，麻烦各位帮忙看下驱动程序有何问题，谢谢！ //整屏显示红色 //3.5寸液晶驱动 void LCD_DATA_OUT(unsigned int data) { unsigned char data_bit_cnt = 0; unsigned long temp1 = 0,temp2 = 0; for(data_bit_cnt = 0;data_bit_cnt < 16; data_bit_cnt++) { if(data_bit_cnt < 8) { if(BIT_CHK(data,data_bit_cnt)) temp1 |= (1<<(data_bit_cnt + 2)); } else { if(BIT_CHK(data,data_bit_cnt)) temp2 |= (1<<(data_bit_cnt + 7)); } } LPC_GPIO0 -> FIOSET |= temp2; LPC_GPIO2 -> FIOSET |= temp1; } //写寄存器函数 void LCD_Write_Command(unsigned int Command) { LCD_CS_L; LCD_RS_L;//Wirte address LCD_DATA_OUT(Command); LCD_WR_L; LCD_WR_H; LCD_CS_H; } void LCD_Wtire_Data(unsigned int data) { LCD_RS_H;//Write data LCD_CS_L; LCD_DATA_OUT(data); LCD_WR_L; LCD_WR_H; LCD_CS_H; } //清屏函数 //color:要清屏的填充色 void LCD_Clear(unsigned int color) { int i = 0; /* LCD_Write_Command(0X2A); LCD_Wtire_Data(0X00);//VCI1 VCL VGH VGL DDVDH VREG1OUT power amplitude setting(0X00); LCD_Wtire_Data(0X00);//VCI1 VCL VGH VGL DDVDH VREG1OUT power amplitude setting(0X00); LCD_Wtire_Data(0X01);//VCI1 VCL VGH VGL DDVDH VREG1OUT power amplitude setting(0X01); LCD_Wtire_Data(0XdF);//VCI1 VCL VGH VGL DDVDH VREG1OUT power amplitude setting(0X3F); LCD_Write_Command(0X2B); LCD_Wtire_Data(0X00);//VCI1 VCL VGH VGL DDVDH VREG1OUT power amplitude setting(0X00); LCD_Wtire_Data(0X00);//VCI1 VCL VGH VGL DDVDH VREG1OUT power amplitude setting(0X00); LCD_Wtire_Data(0X01);//VCI1 VCL VGH VGL DDVDH VREG1OUT power amplitude setting(0X01); LCD_Wtire_Data(0X3F);//VCI1 VCL VGH VGL DDVDH VREG1OUT power amplitude setting(0XDF); */ LCD_Write_Command(0X2C); for (i=0; i<153600; i++) { LCD_Wtire_Data(color);//VCI1 VCL VGH VGL DDVDH VREG1OUT power amplitude setting(color); } } void LCD_Init(void) { LCD_Write_Command(0X11); delayms(20); LCD_Write_Command(0XD0);//VCI1 VCL VGH VGL DDVDH VREG1OUT power amplitude setting LCD_Wtire_Data(0X07); LCD_Wtire_Data(0X42); LCD_Wtire_Data(0X1D); LCD_Write_Command(0XD1);//VCOMH VCOM_AC amplitude setting LCD_Wtire_Data(0X00); LCD_Wtire_Data(0X1a); LCD_Wtire_Data(0X09); LCD_Write_Command(0XD2);//Operational Amplifier Circuit Constant Current Adjust , charge pump frequency setting LCD_Wtire_Data(0X01); LCD_Wtire_Data(0X22); LCD_Write_Command(0XC0);//REV SM GS LCD_Wtire_Data(0X10); LCD_Wtire_Data(0X3B); LCD_Wtire_Data(0X00); LCD_Wtire_Data(0X02); LCD_Wtire_Data(0X11); LCD_Write_Command(0XC5);// Frame rate setting = 72HZ when setting 0x03 LCD_Wtire_Data(0X03); LCD_Write_Command(0XC8);//Gamma setting LCD_Wtire_Data(0X00); LCD_Wtire_Data(0X25); LCD_Wtire_Data(0X21); LCD_Wtire_Data(0X05); LCD_Wtire_Data(0X00); LCD_Wtire_Data(0X0a); LCD_Wtire_Data(0X65); LCD_Wtire_Data(0X25); LCD_Wtire_Data(0X77); LCD_Wtire_Data(0X50); LCD_Wtire_Data(0X0f); LCD_Wtire_Data(0X00); LCD_Write_Command(0XF8); LCD_Wtire_Data(0X01); LCD_Write_Command(0XFE); LCD_Wtire_Data(0X00); LCD_Wtire_Data(0X02); LCD_Write_Command(0X20);//Exit invert mode LCD_Write_Command(0X36); //LCD_Wtire_Data(0X2b); LCD_Wtire_Data(0X08);//原来是a LCD_Write_Command(0X3A); LCD_Wtire_Data(0X55);//16位模式 LCD_Write_Command(0X2b); LCD_Wtire_Data(0X00); LCD_Wtire_Data(0X00); LCD_Wtire_Data(0X01); LCD_Wtire_Data(0X3F); LCD_Write_Command(0X2a); LCD_Wtire_Data(0X00); LCD_Wtire_Data(0X00); LCD_Wtire_Data(0X01); LCD_Wtire_Data(0XdF); delayms(120); LCD_Write_Command(0X29); delayms(50); LCD_BACKLIGHT_H; //点亮背光 LCD_Clear(RED); } int main(void) { SystemInit(); PORT_Init(); LCD_Init(); while(1) { } } [/mw_shl_code]
