如何用STM32的片内Flash存储中文字库

在嵌入式体系中，本钱往往是灵敏的，假如你的Flash足够大，就可以省去片外Flash，我用结构体完成了该功用，并共享给广阔网友，最终附有下载链接。

在fonts.h中：

typedef struct _tFont
{
const uint16_t *table;
uint16_t Width;
uint16_t Height;

} sFONT;

extern sFONT Font8x8;
extern sFONT Font8x12_bold;
extern sFONT Font8x12;
extern sFONT Font12x12;
extern sFONT Font16x24;

#define GL_Font8x8 Font8x8
#define GL_Font8x12_bold Font8x12_bold
#define GL_Font8x12 Font8x12
#define GL_Font12x12 Font12x12
#define GL_Font16x24 Font16x24

在fonts.c中

const uint16_t ASCII16x24_Table []={………………};//字模

sFONT Font16x24 = {
ASCII16x24_Table,
16,
24,
};

sFONT Font12x12 = {
ASCII12x12_Table,
12,
12,
};

sFONT Font8x12 = {
ASCII8x12_Table,
8,
12,
};

sFONT Font8x12_bold ={
ASCII8x12_bold_Table,
8,
12,
};

sFONT Font8x8 = {
ASCII8x8_Table,
8,
8,
};

在main.c中调用：

#include “user_config.h”

uint8_t test1[]=”你见，或许不见我，我就在那里，不悲不喜;”;
uint8_t test2[]=”你念，或许不念我，我就在那里，不来不去;”;
uint8_t test3[]=”你爱，或许不爱我，爱就在那里，不增不减;”;
uint8_t test4[]=”你跟，或许不跟我，我的手就在你手里，”;
uint8_t test5[]=”不舍 不弃.”;
uint8_t test6[]=”默然 相爱”;
uint8_t test7[]=”幽静 喜爱”;

int main(void)
{
u8 i,j,k;
NVIC_Config();
SysTick_Init();
STM_EVAL_LEDInit(LED1);
STM_EVAL_LEDInit(LED2);
STM_EVAL_LEDInit(LED3);
STM_EVAL_LEDInit(LED4);
USART_Config( COM1,115200);
STM3210E_LCD_Init();

LCD_Clear(LCD_COLOR_MAGENTA);
LCD_SetColors(LCD_COLOR_RED,LCD_COLOR_CYAN);

LCD_DisplayStringLine(LCD_LINE_0, (uint8_t *)MESSAGE1);
LCD_DisplayStringLine(LCD_LINE_1, (uint8_t *)MESSAGE2);
LCD_DisplayStringLine(LCD_LINE_2, (uint8_t *)MESSAGE3);
LCD_DisplayStringLine(LCD_LINE_3, (uint8_t *)MESSAGE4);

printf(“nr %s”, MESSAGE1);
printf(” %s”, MESSAGE2);
printf(” %snr”, MESSAGE3);

LCD_Clear(LCD_COLOR_BLUE);

GL_Clear(GL_Grey);
GL_SetTextColor(GL_Blue);
GL_SetBackColor(GL_Yellow);
GL_SetFont(GL_FONT_GB2312);
LCD_ClearLine(LINE(0)); // disp yellow line
LCD_ClearLine(LINE(9));
GL_DisplayAdjStringLine(0,220,(uint8_t*)”Loading…”,GL_FALSE);
GL_DisplayAdjStringLine(LINE(2),310,test1,GL_TRUE); //假如横屏，Y轴递减
GL_DisplayAdjStringLine(LINE(3),310,test2,GL_TRUE);
GL_DisplayAdjStringLine(LINE(4),310,test3,GL_TRUE);
GL_DisplayAdjStringLine(LINE(5),310,test4,GL_TRUE);
GL_DisplayAdjStringLine(LINE(6),310,test5,GL_TRUE);
GL_DisplayAdjStringLine(LINE(7),310,test6,GL_TRUE);
GL_DisplayAdjStringLine(LINE(8),310,test7,GL_TRUE);
GL_DisplayAdjStringLine(LINE(9),130,”蔡志威”,GL_TRUE);
GL_SetFont(GL_FONT_SMALL);
//SetFont(GL_Font8x12_bold);
GL_DisplayAdjStringLine(220,80,” 2013-10-08″,GL_TRUE);
while (1)
{
}
}
