RealTouch硬件鼠标支持了，各位大神赶紧把它融合到RTGUI里面去吧。

RA8875的驱动现在已经加入硬件图形光标支持，可以在RealTouch中使用了。
首先，需要做一个鼠标光标图像数据，下面是取了一个仿windows光标的数据：
const uint8_t cursor[256]={ 0xaa,0xaa,0xaa,0xaa,0xaa,0xaa,0xaa,0xa5, 0xaa,0xaa,0xaa,0xaa,0xaa,0xaa,0xaa,0x91, 0xaa,0xaa,0xaa,0xaa,0xaa,0xaa,0xaa,0x41, 0xaa,0xaa,0xaa,0xaa,0xaa,0xaa,0xa9,0x01, 0xaa,0xaa,0xaa,0xaa,0xaa,0xaa,0xa4,0x01, 0xaa,0xaa,0xaa,0xaa,0xaa,0xaa,0x90,0x01, 0xaa,0xaa,0xaa,0xaa,0xaa,0xaa,0x40,0x01, 0xaa,0xaa,0xaa,0xaa,0xaa,0xa9,0x00,0x01, 0xaa,0xaa,0xaa,0xaa,0xaa,0xa4,0x00,0x01, 0xaa,0xaa,0xaa,0xaa,0xaa,0x90,0x00,0x01, 0xaa,0xaa,0xaa,0xaa,0xaa,0x40,0x00,0x01, 0xaa,0xaa,0xaa,0xaa,0xa9,0x00,0x00,0x01, 0xaa,0xaa,0xaa,0xaa,0xa4,0x00,0x00,0x01, 0xaa,0xaa,0xaa,0xaa,0x90,0x00,0x00,0x01, 0xaa,0xaa,0xaa,0xaa,0x40,0x00,0x00,0x01, 0xaa,0xaa,0xaa,0xa9,0x00,0x00,0x00,0x01, 0xaa,0xaa,0xaa,0xaa,0x55,0x00,0x00,0x01, 0xaa,0xaa,0xaa,0xaa,0xaa,0x40,0x00,0x01, 0xaa,0xaa,0xaa,0xaa,0xaa,0x90,0x00,0x01, 0xaa,0xaa,0xaa,0xaa,0xaa,0x40,0x00,0x01, 0xaa,0xaa,0xaa,0xaa,0xaa,0x40,0x15,0x01, 0xaa,0xaa,0xaa,0xaa,0xa9,0x00,0x1a,0x41, 0xaa,0xaa,0xaa,0xaa,0xa9,0x00,0x6a,0x91, 0xaa,0xaa,0xaa,0xaa,0xa4,0x00,0x6a,0xa5, 0xaa,0xaa,0xaa,0xaa,0xa4,0x01,0xaa,0xa9, 0xaa,0xaa,0xaa,0xaa,0xa0,0x01,0xaa,0xaa, 0xaa,0xaa,0xaa,0xaa,0x90,0x06,0xaa,0xaa, 0xaa,0xaa,0xaa,0xaa,0x90,0x06,0xaa,0xaa, 0xaa,0xaa,0xaa,0xaa,0x90,0x0a,0xaa,0xaa, 0xaa,0xaa,0xaa,0xaa,0x90,0x1a,0xaa,0xaa, 0xaa,0xaa,0xaa,0xaa,0xa5,0x6a,0xaa,0xaa, 0xaa,0xaa,0xaa,0xaa,0xaa,0xaa,0xaa,0xaa };
因为RA8875的光标数据是由两个自定义颜色，一个屏幕背景色，一个屏幕背景色反色4种颜色组成的，每个颜色用2个位表示，每个字节代表4个点的颜色，所以32x32的光标图像需要用256个字节（32X32X2/8），这个取模比较难搞，这里提供一个经过笔者好久才制作好的3色光标，和windows的一样。
下面是在RA8875中载入图形光标的函数：
static void _set_mouse_image(const uint8_t *mouse_img) { uint32_t i,j; LCD_write_reg(0x84, 0xFF);//GCC0 LCD_write_reg(0x85, 0x00);//GCC1 LCD_write_reg(0x41, 2<<2);//write to gc _set_write_cursor(0, 0); LCD_CmdWrite(MRWC);//set CMD02 to prepare data write for(i=0;i<32;i++) { for(j=0;j<8;j++) { LCD_DataWrite(*mouse_img++); } } LCD_write_reg(0x41, (1 << 7) | (0 <<2 ));//display cursor }
接下来就是设置光标位置的函数了，如下：
```static void _set_mouse_position(uint32_t X, uint32_t Y)
{
LCD_CmdWrite(0x81);
LCD_DataWrite(X>>8);
LCD_CmdWrite(0x80);
LCD_DataWrite(X);

LCD_CmdWrite(0x83);
LCD_DataWrite(Y>>8);
LCD_CmdWrite(0x82);
LCD_DataWrite(Y);

}```
附件中提供一个开启硬件光标的RA8875驱动，可以直接替换RealTouch主程序中的RA8875.c文件，这样烧录到RealTouch就是可以看到光标了。在finsh中使用set_mouse_XY(X,Y)可以进行设置光标的位置。因为还不懂如何与RTGUI关联，所以暂时提供这个，等待各位制作GUI的大神们加入RTGUI中，支持硬件光标。
