RA8889/RA8876显示自定义ASCII字符方法

BWSU

本文介绍用户自己生成的ASCII字库如何通过RA8889/RA8876显示到液晶屏上。

一、实例效果图：



二、演示代码：

1. int main(void)
   
2. {
   
3. unsigned short x,y;
   
4. 
   
5. /* System Clocks Configuration */
   
6. RCC_Configuration();
   
7. delay_init(72);
   
8. GPIO_Configuration();
   
9. //NVIC_Configuration();
   
10. //SPI_Peripheral_Init();
    
11. 
    
12. /* Enable the FSMC Clock */
    
13. RCC_AHBPeriphClockCmd(RCC_AHBPeriph_FSMC, ENABLE);
    
14. delay_ms(1);
    
15. FSMC_LCD_Init_H();
    
16. 
    
17. /*RA8889初始化*/
    
18. RA8889_Initial();
    
19. 
    
20. /*清屏，填充黑色0x0*/
    
21. BTE_Solid_Fill(0,canvas_image_width,0,0,0x0,LCD_Width,LCD_Height);
    
22. 
    
23. /*MCU写入ASCII字符功能例程测试，不支持MCU_16bit_ColorDepth_24bpp_Mode_1 */
    
24. x=30;
    
25. y=50;
    
26. lcdPutString8x12(x,y,color65k_black,color65k_yellow,0,"The things I want to know are in books, my best friend is the man ");
    
27. lcdPutString16x24(x,y+20,color65k_black,color65k_yellow,0,"who'll get me a book I ain't read.");
    
28. lcdPutString16x24(x+16*14,y+50,color65k_green,color65k_yellow,1," --Abraham Lincoln ");
    
29. lcdPutString32x48(x,y+100,color65k_white,color65k_yellow,1,"ASCII font lib is ");
    
30. lcdPutString32x48(x,y+150,color65k_white,color65k_yellow,1,"stored in the MCU's");
    
31. lcdPutString32x48(x,y+200,color65k_white,color65k_yellow,1,"FLASH.");
    
32. 
    
33. while(1);
    
34. }

三、程序流程图：



该方法是将制作好的ASCII字库放在MCU的FLASH中进行引用，字符数量为95个，编码区间0x20~0x7E，通过编码即可索引，并调用相应的数据，通过RA8889/RA8876描点显示出来。
