求3.5寸320*480控制芯片ILI9486L的驱动程序

zhang1116quan · 发表于 2015-5-19 08:59:16

最近在调3.5寸ILI9486L控制芯片的程序，现在可以刷屏显示颜色，但是刷屏的时候有时会有部分区域花屏，显示黑色的条纹，有没有调试好的ILI9486L的程序，希望借鉴一下。附上我的程序：
//写寄存器函数
//regval:寄存器值
void LCD_WR_REG(vu16 regval)
{
*(__IO u16 *)(Bank1_LCD_REG)=regval;//写入要写的寄存器序号
}
//写LCD数据
//data:要写入的值
void LCD_WR_DATA(vu16 data)
{
*(__IO u16 *)(Bank1_LCD_RAM)=data;
}
//读LCD数据
//返回值:读到的值
u16 LCD_RD_DATA(void)
{
return *(__IO u16 *)(Bank1_LCD_RAM);
}
//写寄存器
//LCD_Reg:寄存器地址
//LCD_RegValue:要写入的数据
void LCD_WriteReg(vu16 LCD_Reg, vu16 LCD_RegValue)
{
*(__IO u16 *)(Bank1_LCD_REG) = LCD_Reg; //写入要写的寄存器序号
*(__IO u16 *)(Bank1_LCD_RAM) = LCD_RegValue;//写入数据
}

//开始写GRAM
void LCD_WriteRAM_Prepare(void)
{
*(__IO u16 *)(Bank1_LCD_REG)=0x002C;
}

//设置光标位置
//Xpos:横坐标
//Ypos:纵坐标
void LCD_SetCursor(u16 Xpos, u16 Ypos)
{
LCD_WR_REG(0X2A);
LCD_WR_DATA(Xpos>>8);
LCD_WR_DATA(Xpos&0XFF);
LCD_WR_REG(0X2B);
LCD_WR_DATA(Ypos>>8);
LCD_WR_DATA(Ypos&0XFF);
}

//画点
//x,y:坐标
//color:此点的颜色
void LCD_PutPixel(u16 x,u16 y,u16 color)
{
LCD_SetCursor(x,y);//设置光标位置
*(__IO u16 *)(Bank1_LCD_REG)=0x002C;//开始写入GRAM
*(__IO u16 *)(Bank1_LCD_RAM)=color;
}

//读取个某点的颜色值
//x,y:坐标
//返回值:此点的颜色
u16 LCD_ReadPoint(u16 x,u16 y)
{
u16 color;
LCD_SetCursor(x,y);
LCD_WR_REG(0X2E); //发送读GRAM指令
LCD_RD_DATA(); //无效数据
color=*(__IO u16 *)(Bank1_LCD_RAM); //实际坐标颜色
return color;
