取模软件配置

测试示例所用的字体取模软件为PCtoLCD2002，关于它的详细使用说明见如下文档：

PCtoLCD2002使用说明

PCtoLCD2002软件具体设置如下：

  • 字体和尺寸选择
MSP130W-002.jpg
模式需要选择字符模式
字体可以根据需求选择，比如选择宋体
字宽和字高可以根据需求选择，中英文常用的字体尺寸如下：
中文（字宽x字高）：16x16、24x24、32x32
英文（字库x字高）：6x8、6x12、8x16、12x24、16x32（对应的字体尺寸需要分别设置为12x8、12x12、16x16、24x24、32x32）
修改点阵大小可以根据需求设置，一般设置为0
  • 字模选项设置
字模选项设置有多种情况，不同的设置，代码处理方法不一样。这里就选取下面的设置为例，后续的函数代码都是基于此设置编写。
MSP130W-001.jpg
点阵格式选择阴码
取模方式选择逐行式
取模走向选择顺向（高位在前）
输出数制选择十六进制数
自定义格式选择C51格式

底层支撑函数

  • LCD_SetWindows
该函数实现因驱动IC而异（不同的驱动IC设置坐标值命令和原理有差异），但是原理基本一样，都是设置起始坐标和结束坐标，设置一块显示区域
举例如下（ILI9341为例）
void LCD_SetWindows(u16 xStar, u16 yStar,u16 xEnd,u16 yEnd)
{	
	LCD_WR_REG(lcddev.setxcmd);	
	LCD_WR_DATA(xStar>>8);
	LCD_WR_DATA(0x00FF&xStar);		
	LCD_WR_DATA(xEnd>>8);
	LCD_WR_DATA(0x00FF&xEnd);

	LCD_WR_REG(lcddev.setycmd);	
	LCD_WR_DATA(yStar>>8);
	LCD_WR_DATA(0x00FF&yStar);		
	LCD_WR_DATA(yEnd>>8);
	LCD_WR_DATA(0x00FF&yEnd);

	LCD_WriteRAM_Prepare();	//开始写入GRAM		
}
  • Lcd_WriteData_16Bit
该函数就是往GRAM里面设置像素颜色值，然后显示出来
举例如下（ILI9341为例）
void Lcd_WriteData_16Bit(u16 Data)
{	
      LCD_CS_CLR;
      LCD_RS_SET;  
      SPI_WriteByte(SPI2,Data>>8);
      SPI_WriteByte(SPI2,Data);
      LCD_CS_SET;
}
  • LCD_DrawPoint
其实就是利用LCD_SetWindows函数和Lcd_WriteData_16Bit函数显示一个像素点
举例如下（ILI9341为例）
void LCD_DrawPoint(u16 x,u16 y)
{
	LCD_SetCursor(x,y);//设置光标位置 
	Lcd_WriteData_16Bit(POINT_COLOR); 
}

英文字符取模

  • 重要说明
因为在程序里是按照ASCII码偏移量搜索需要显示的英文字符的，所以需要将整套ASCII字符都取模。
ASCII码字符如下所示（最前面的空格也要包含）：
ASCII字符： !"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~
  • 6x8英文字体取模说明
尺寸设置如下图所示：
