單片機源程序如下:
- #include "stm8s.h"
- #include "stm8s_clk.h"
- #include "stm8s_i2c.h"
- #include "ili9328.h"
- #include "gui.h"
- #include "eeprom.h"
- unsigned char a=54;
- unsigned char b;
- void main(void)
- { CLK_HSIPrescalerConfig(CLK_PRESCALER_HSIDIV1);//時鐘初始化
- IIC_int(); //iic初始化
- LCD_init(); // 液晶顯示器初始化
- LCD_Clear(LGRAY);
- Draw_Button(5,5,235,265);
- POINT_COLOR = RED;
- BACK_COLOR = LGRAY;
- LCD_ShowString(10,289,"QF-STM8");
- Draw_Frame(10,15,230,250,"eeprom ");
-
-
- SetButton(12,30,206,243);
- LCD_Fill(14,32, 204,245,BLACK);
- POINT_COLOR = GREEN;
- BACK_COLOR = BLACK;
-
-
- LCD_ShowString(15,35,"i2c read 24c02");
- At24c02Write(0x10,a);
- LCD_ShowString(15,60,"24c02 write:");
- LCD_ShowNum(120,60,a,2);
- b=At24c02Read(0x10);
- LCD_ShowString(15,80,"24c02 read:");
- LCD_ShowNum(120,80,b,2);
- if(a != b)
- {
- LCD_ShowString(50,120,"read EEROR");
- }
- else
