按键切换LCD背景色，采用嵌入式设计

单片机源程序如下:

#include "led.h"
#include "delay.h"
#include "sys.h"
#include "usart.h"
#include "lcd.h"
#include "stm32f10x_gpio.h"
#define key1 GPIO_ReadInputDataBit(GPIOA,GPIO_Pin_15)
#include "stm32f10x_rcc.h"
void key_init(void)
{
GPIO_InitTypeDef GPIO_InitStructure;
RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA,ENABLE);
GPIO_Init(GPIOA,&GPIO_InitStructure);
GPIO_InitStructure.GPIO_Mode=GPIO_Mode_IPU;
GPIO_InitStructure.GPIO_Pin=GPIO_Pin_15;
GPIO_InitStructure.GPIO_Speed=GPIO_Speed_10MHz;
}
int main(void)
{ void key_init(void);
u8 x=0;
LCD_Display_Dir(0);
//u8 lcd_id[12]; //存放LCD ID字符串
delay_init(); //延时函数初始化
uart_init(9600); //串口初始化为9600
LED_Init(); //初始化与LED连接的硬件接口
LCD_Init();
POINT_COLOR=BLUE;
//sprintf((char*)lcd_id,"LCD ID:%04X",lcddev.id);//将LCD ID打印到lcd_id数组。
while(1)
{
while(!key1)
{
switch(x)
{
case 0:{LCD_Fill(0,0,240,107,RED);
LCD_Fill(0,107,240,214,WHITE);
LCD_Fill(0,214,240,320,BLUE);}break;
case 1:{LCD_Fill(0,0,240,107,WHITE);
LCD_Fill(0,107,240,214,BLUE);
LCD_Fill(0,214,240,320,RED);}break;
case 2:{LCD_Fill(0,0,240,107,BLUE);
LCD_Fill(0,107,240,214,RED);
LCD_Fill(0,214,240,320,WHITE);}break;
}
LCD_ShowString(85,40,200,24,24,"HE XI");
LCD_ShowString(70,150,300,300,24,"LUO HENG");
LCD_ShowString(55,255,200,200,24,"SHAO PEIJUN");
//LCD_ShowString(30,90,200,16,16,"ATOM@ALIENTEK");
//LCD_ShowString(30,110,200,16,16,lcd_id); //显示LCD ID
//LCD_ShowString(30,130,200,12,12,"2014/3/7");
// if(key1==0)
//{delay_ms(20);
x++;//}
delay_ms(300);
if(x==3)x=0;
LED0=!LED0;
LED1=!LED1;
delay_ms(150);
LED0=!LED0;
LED1=!LED1;
//delay_ms(1);
}
}
}
