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。
先上一张实例效果图:
再上程序代码:
int main(void)
{unsigned short x,y;/* System Clocks Configuration */RCC_Configuration(); delay_init(72); GPIO_Configuration(); //NVIC_Configuration(); //SPI_Peripheral_Init();/* Enable the FSMC Clock */RCC_AHBPeriphClockCmd(RCC_AHBPeriph_FSMC, ENABLE);delay_ms(1);FSMC_LCD_Init_H(); /*RA8889初始化*/RA8889_Initial();/*清屏,填充黑色0x0*/BTE_Solid_Fill(0,canvas_image_width,0,0,0x0,LCD_Width,LCD_Height);/*MCU写入ASCII字符功能例程测试,不支持MCU_16bit_ColorDepth_24bpp_Mode_1 */x=30;y=50;lcdPutString8x12(x,y,color65k_black,color65k_yellow,0,"The things I want to know are in books, my best friend is the man ");lcdPutString16x24(x,y+20,color65k_black,color65k_yellow,0,"who'll get me a book I ain't read.");lcdPutString16x24(x+16*14,y+50,color65k_green,color65k_yellow,1," --Abraham Lincoln ");lcdPutString32x48(x,y+100,color65k_white,color65k_yellow,1,"ASCII font lib is ");lcdPutString32x48(x,y+150,color65k_white,color65k_yellow,1,"stored in the MCU's");lcdPutString32x48(x,y+200,color65k_white,color65k_yellow,1,"FLASH.");while(1);
}
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。
