首先是LCD的RAM写子函数：

void LCD_WriteRAM(u16 RGB_Code){  GPIO_SetBits(LCD_RS_PORT,LCD_RS_PIN);       GPIO_Write(LCD_PORT_PORT,RGB_Code>>8);  //Delay(5);  GPIO_ResetBits(LCD_WR_PORT,LCD_WR_PIN);   //Delay(10);  GPIO_SetBits(LCD_WR_PORT,LCD_WR_PIN);  GPIO_Write(LCD_PORT_PORT,RGB_Code); // Delay(10);  GPIO_ResetBits(LCD_WR_PORT,LCD_WR_PIN);   //Delay(10);  GPIO_SetBits(LCD_WR_PORT,LCD_WR_PIN);}

LCD从RAM读取字符并进行显示的子函数：

void LCD_DrawChar(u8 Xpos, u16 Ypos, const u16 *c){  u32 index = 0, i = 0;  u8 Xaddress = 0;     Xaddress = Xpos;    LCD_SetCursor(Xaddress, 319-Ypos);    for(index = 0; index < 24; index++)  {    LCD_WriteRAM_Prepare(); /* Prepare to write GRAM */    for(i = 0; i < 16; i++)    {      if((c[index] & (1 << i)) == 0x00)      {        LCD_WriteRAM(BackColor);      }      else      {        LCD_WriteRAM(TextColor);      }    }       LCD_CtrlLinesWrite(LCD_NCS_GPIO_PORT, LCD_NCS_PIN, Bit_SET);     Xaddress++;    LCD_SetCursor(Xaddress, 319-Ypos);  }}

ASCII码转换的基本

void LCD_DisplayChar(u8 Line, u16 Column, u8 Ascii){  Ascii -= 32;  LCD_DrawChar(Line, Column, &ASCII_Table[Ascii * 24]);}

可以应用于主函数的数字显示函数：

void LCD_ShowNum(uint8_t x,uint16_t y,uint16_t data){LCD_DisplayChar(x,y,data/10000+48); LCD_DisplayChar(x,(y+25),data%10000/1000+48);   // %10000LCD_DisplayChar(x,(y+50),data%1000/100+48); LCD_DisplayChar(x,(y+75),data%100/10+48); LCD_DisplayChar(x,(y+100),data%10+48);}

可以用于主函数的字符显示函数：

void LCD_DisplayStringLine(u8 Line, u8 *ptr){  u32 i = 0;  u16 refcolumn =0;  /* Send the string character by character on lCD */  while ((*ptr != 0) & (i < 20))  {    /* Display one character on LCD */    LCD_DisplayChar(Line*FONT_HEIGHT, refcolumn, *ptr);    /* Decrement the column position by 16 */    refcolumn += FONT_WIDTH;    /* Point on the next character */    ptr++;    /* Increment the character counter */    i++;  }}
