GUI开发--LCD屏幕的使用（非第三方库）--笔记
导：界面交互需要GUI，GUI需要文字和图片，所有此处总结在M4芯片上实现GUI的基本操作！该芯片具有160K大小的内存，有512K的flash；故而没有使用第三方库！
LCD屏幕的使用--笔记
1.汉字显示-两种方式
·字符数组格式
·汉字库格式
2.双色2位图显示
3.真彩色16位图显示
条件：
屏幕：ST7789 尺寸：320*240
配置软件：
基础的驱动可以实现：LCD_Address_Set 和 LCD_WR_DATA的接口可以用软件或硬件spi实现
可实现的基本效果
1.汉字显示（数组形式）
文字显示格式设置
存放在一个数据结果中：如下
const typFNT_GB16 tfont16[]={
"升",0x80,0x04,0xE0,0x05,0x3C,0x04,0x20,0x04,0x20,0x04,0x20,0x04,0x20,0x04,0xFF,0x7F,
0x20,0x04,0x20,0x04,0x20,0x04,0x10,0x04,0x10,0x04,0x08,0x04,0x04,0x04,0x02,0x04,/*"升",0*/
/* (16 X 16 , 宋体 )*/
"级",0x08,0x00,0xC8,0x3F,0x04,0x21,0x04,0x11,0x12,0x11,0x1F,0x09,0x08,0x39,0x04,0x21,
0x82,0x22,0x9F,0x22,0x82,0x14,0x80,0x14,0x58,0x08,0x47,0x14,0x22,0x22,0x80,0x41,/*"级",1*/
/* (16 X 16 , 宋体 )*/
"中",0x80,0x00,0x80,0x00,0x80,0x00,0x80,0x00,0xFC,0x1F,0x84,0x10,0x84,0x10,0x84,0x10,
0x84,0x10,0x84,0x10,0xFC,0x1F,0x84,0x10,0x80,0x00,0x80,0x00,0x80,0x00,0x80,0x00,/*"中",2*/
/* (16 X 16 , 宋体 )*/
}其中，对汉字显示定义结构体如下：
结构体定义：
typedef struct
{
unsigned char Index[2]; //汉字索引号
unsigned char Msk[32]; //对应汉字的

#endif效果显示：
优点：不依赖外部flash，根据自己喜欢的汉字裁剪并显示、灵活可控
确定：汉字太少，一旦确定不能改变；汉字一旦多消耗太多的ram或rom；造成负担
3.汉字显示--（汉字 字库显示）
实现的方式：先将汉字字库文件存放在某一个存储器的位置a
然后当要显示某一个汉字的时候，会根据汉字，先将汉字的16进制码(比如汉字“你”对应的16进制为C4 E3),根据根据偏移量计算区码和位码（类似算出在x、y坐标或者类似住的地址-某个区的某个栋）；然后计算出该字的具体偏移位置ulOffset；
16进制：
qm = *(s) - 0xaf; //区码 -161->A1
wm = *(s + 1) - 0xa0;//位码 -A1
ulOffset = (INT32U)((qm-1) * 94 + (wm-1)) * 72;//计算区位码
然后从位置a（汉字字库存储的位置）的偏移ulOffset处读取出该汉字的点阵16进制码
ExFlash_SeekHzk("HZK.BIN",hzflashbuf,ulOffset,sizeof(hzbuf));
接下来就是显示的情况和数组的显示方式一样：
memcpy(hzbuf,hzflashbuf,sizeof(hzbuf));
for(y = 0; y < 16; y++)
{
for(x = 0; x < 16; x++)
{
k = x % 8;
if (hzbuf[y * 2 + x / 8] & (0x80 >> k))
{
xx = x0 + x;
LCD_DrawPoint( xx, y + y0, ForeColor);
}
}
}最终调用画点函数实现具体的点阵点亮操作；
显示的效果和数组的一模一样；
上述的驱动是16进制，其他进制的，比如24进制的不一样了（主要是计算区码和位码，同一个子需要的点阵数量不一样就要在点阵画点操作有所区别了）
qm = *(s) - 0xaf; //161->A1
wm = *(s + 1) - 0xa0;//A1
ulOffset = (INT32U)((qm-1) * 94 + (wm-1)) * 72;//计算区位码
ExFlash_SeekHzk("HZK.BIN",hzflashbuf,ulOffset,sizeof(hzbuf));
memcpy(hzbuf,hzflashbuf,sizeof(hzbuf));
for( i = 0; i < 24; ++i)
for( j = 0; j < 3; ++j)
for( k = 0; k < 8; k++)
if(((hzbuf[i* 3 + j] >> (7 - k)) & 0x1) != NULL)
{
current_start_x = x0 + i ;//24*24的是纵向排列的i对应的是x
current_start_y = y0 + j * 8 + k;
LCD_DrawPoint( current_start_x,current_start_y , ForeColor);
} 附加：汉字字库如何生成（需要软件0点阵字库生成器-自行网上下载，免费的有很多！）
注意：汉字字库文件，存储大小，常用的16号字体，需要260多k，24号字体需要400k左右（提供参考），对空间要求严格者需要慎重！！！
4.双色图（除开背景色-也可以叫单色图）-图像实现
显示双色图--的这个操作--对于图片很多的芯片，相对余全真彩色--节省空间会很有很大助力！
打开软件：安装图中的要求进行设置（图中的要求会对应到后面的驱动和画点函数顺序的操作）
上述的配置对应到驱动如下（驱动不一样--配置也要修改）

}4.16位真彩色图的实现 推荐两款软件
推荐两款软件。
第一个如下的这个软件Img2Lcd.exe（需要设置驱动的参数--包含头，高低位...等）
软件特色
Image2Lcd 能把各种来源的图片转换成特定的数据格式以用来匹配单片机系统所需要的显示数据格式
Image2Lcd支持的输入图像格式包括：BMP, WBMP, JPG, GIF, WMF, EMF, ICO, 等等。 Image2Lcd的输出数据类型包括定制的二进制类型、C语言数组类型和标准的BMP格式、WBMP格式
Image2Lcd能可视调节输入图象的数据扫描方式、灰度(颜色数)、图像数据排列方式、亮度、对比度、等等
对于包含了图像头数据保存的图像数据文件，Image2Lcd能重新打开作为输入图像
****支持所有的点阵LCD所需要的特殊显示数据格式。
可视调节输出图像效果。
256色模式下支持用户调色板(TIFF格式)。
支持4096色图像输出。
以二进制类型和C语言数组类型(文本)两种方式保存数据，方便单片机开发者的不同需要。
保存的数据支持LSB First/MSB First(很多单片机系统WORD高低字节排列与PC相反)。
可以保存图像为指定颜色数的BMP格式图像。
即时图示当前设置的数据格式。
第二个软件是bmp2h.exe（规定好了驱动的方式）
位图变换(bmp2h)是一款可以把bmp格式的图片转化成64K色的数组数据信息
应用：
点一下功能键“添加将一个bmp图片添加进去，随后点一下功能键“变换就会转化成图片数组文档。表明：假如要应用转化成的图片数组数据信息，必须在转化成的c文档开始添加一条句子：#define WIN32
