51单片机 TFT彩屏 怎么设置坐标原点

我现在的原点是在左下角，导致字符倒着显示，怎么把坐标原点设置到左上角？
//------------------ Set GRAM area ---------------//
Write_Cmd_Data(0x0050, 0x0000); // Horizontal GRAM Start Address
Write_Cmd_Data(0x0051, 0x00EF); // Horizontal GRAM End Address
Write_Cmd_Data(0x0052, 0x0000); // Vertical GRAM Start Address
Write_Cmd_Data(0x0053, 0x013F); // Vertical GRAM Start Address
Write_Cmd_Data(0x0060, 0x2700); // Gate Scan Line
Write_Cmd_Data(0x0061, 0x0001); // NDL,VLE, REV
Write_Cmd_Data(0x006A, 0x0000); // set scrolling line
Write_Cmd_Data(0x20, 0x0000); // GRAM horizontal Address
Write_Cmd_Data(0x21, 0x0000); // GRAM Vertical Address

Answer 1

320x240的彩屏吧

通过这2条指令设置的
Write_Cmd_Data(0x20, 0x0000); // 设置X轴地址 0-239
Write_Cmd_Data(0x21, 0x0000); // 设置Y轴地址 0-319

追问

应该是01H,60H两个地址
