Molding software configuration

The font modulo software used in the test example is PCtoLCD2002. For detailed instructions on its use, see the following document:

PCtoLCD2002 Instructions for use

The PCtoLCD2002 software is specifically set as follows:

  • Font and size selection
Mode needs to select 字符模式
Fonts can be selected according to needs, such as selection 宋体
The word width and word height can be selected according to the needs. The font sizes commonly used in Chinese and English are as follows:
Chinese (word width x word height):16x16、24x24、32x32、48x48
English (character x word height):6x8、6x12、8x16、12x24、16x32、24x48(The corresponding font size needs to be set to respectively12x8、12x12、16x16、24x24、32x32、48x48)
Modify the dot matrix size can be set according to requirements, generally set to 0
  • Font option setting
There are many situations in the Chinese and English font option setting. Different settings and different code processing methods.
Here is an example of the following settings, the subsequent function code is written based on this setting.
Dot matrix format select 阴码
Modal mode select 逐行式
Molding trend select 顺向(高位在前)
Output number system select 十六进制数
Custom format select C51格式

Bottom support function

  • LCD_SetWindows
The function implementation differs depending on the driver IC (different drive ICs set coordinate values with different commands and principles),
but the principle is basically the same, setting the start and end coordinates and setting a display area.
Examples are as follows (ILI9341 as an example)
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();	//Start writing to GRAM		
}
  • Lcd_WriteData_16Bit
This function is to set the pixel color value into GRAM, and then display it
Examples are as follows (ILI9341 as an example)
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
In fact, the LCD_SetWindows function and the Lcd_WriteData_16Bit function are used to display a pixel.
Examples are as follows (ILI9341 as an example)
void LCD_DrawPoint(u16 x,u16 y)
{
	LCD_SetCursor(x,y);//Set the cursor position
	Lcd_WriteData_16Bit(POINT_COLOR); 
}

English character modulo

1.Because in the program, the English characters that need to be displayed are searched according to the ASCII offset,
so the entire set of ASCII characters needs to be modeled.
2.If you do not need to use a character, you can set the modulo data of the character to {0},
as shown in the following example (take 6x8 size characters as an example)
const unsigned char asc2_0806[95][8]={
   ...  //This example is omitted, the actual application needs to be added
{0},/*"2",18*/ Do not use number 2
{0x00,0x00,0x78,0xB0,0x08,0x88,0x70,0x00},/*"3",19*/
{0x00,0x00,0x30,0x50,0x90,0x78,0x10,0x00},/*"4",20*/
{0},/*"5",21*/ Do not use number 5
{0x00,0x00,0x70,0x80,0xF8,0x88,0x70,0x00},/*"6",22*/
{0},/*"7",23*/ Do not use number 7
{0x00,0x00,0xF8,0x88,0x70,0x88,0x78,0x00},/*"8",24*/
{0},/*"9",25*/ Do not use number 9
   ...  //This example is omitted, the actual application needs to be added
}
3.The ASCII characters are as follows (the first space is also included):
ASCII characters: !"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~
4.The English modulo data fonts are all Default

Chinese character modulo

1.When displaying Chinese characters, the modulo data is obtained by querying the GBK code that needs to display Chinese characters;
2.After the Chinese character is successfully modulo, the corresponding relationship between the Chinese character GBK code and the modulo data is saved through an array of structures.
3.The structure is defined as follows:
//16x16 Chinese font structure definition
typedef struct 
{
       unsigned char Index[2];	//Store Chinese character GBK code
       char Msk[32]; //Store Chinese character modulo data
}typFNT_GB16;  //Structure name can be defined by yourself

\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
//24x24 Chinese font structure definition
typedef struct 
{
       unsigned char Index[2];	//Store Chinese character GBK code
       char Msk[72]; //Store Chinese character modulo data
}typFNT_GB24;  //Structure name can be defined by yourself

\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
//32x32 Chinese font structure definition
typedef struct 
{
       unsigned char Index[2];	//Store Chinese character GBK code
       char Msk[128]; //Store Chinese character modulo data
}typFNT_GB32;  //Structure name can be defined by yourself

\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
//48x48 Chinese font structure definition
typedef struct 
{
       unsigned char Index[2];	//Store Chinese character GBK code
       char Msk[288]; //Store Chinese character modulo data
}typFNT_GB48; //Structure name can be defined by yourself
