一、作品简介

显示当前时间

设备能够通过ntp获取时间，并配置到RTC

具有设置单个闹钟的功能

闹钟可通过按下任意按键关闭

主界面显示当前环境温度与湿度

二、系统框图

三、各部分功能说明和解析

1.RTC配置与时间读取

csi_rtc_t rtc;

void app_rtc_init(app_time_t *time)
{
	ASSERT_INSPECT(csi_rtc_init(&rtc, 0));
	ASSERT_INSPECT(csi_rtc_set_time(&rtc, time));
}

void app_get_time(app_time_t *time)
{
	ASSERT_INSPECT(csi_rtc_get_time(&rtc, time));
	time->tm_year += 1900;
	time->tm_mon += 1;
}

2.主界面代码

裸机操作，通过操作显存显示，最后刷新到屏幕

void app_display_main(app_time_t app_time, int16_t temp, int16_t humi)
{
	uint8_t date_x=24,date_y=10;
	uint8_t time_x=32,time_y=26;
	uint8_t interval = 8;

	uint8_t temp_x=0,temp_y=45;
	uint8_t humi_x=88,humi_y=45;
	
	gui_Clear();
	gui_ShowChar(date_x,date_y,app_time.tm_year/1000%10+'0',16,1); date_x+=interval;
	gui_ShowChar(date_x,date_y,app_time.tm_year/100%10+'0',16,1); date_x+=interval;
	gui_ShowChar(date_x,date_y,app_time.tm_year/10%10+'0',16,1); date_x+=interval;
	gui_ShowChar(date_x,date_y,app_time.tm_year/1%10+'0',16,1); date_x+=interval;
	gui_ShowChar(date_x,date_y,'-',16,1); date_x+=interval;
	gui_ShowChar(date_x,date_y,app_time.tm_mon/10%10+'0',16,1); date_x+=interval;
	gui_ShowChar(date_x,date_y,app_time.tm_mon/1%10+'0',16,1); date_x+=interval;
	gui_ShowChar(date_x,date_y,'-',16,1); date_x+=interval;
	gui_ShowChar(date_x,date_y,app_time.tm_mday/10%10+'0',16,1); date_x+=interval;
	gui_ShowChar(date_x,date_y,app_time.tm_mday/1%10+'0',16,1); date_x+=interval;
	
	gui_ShowChar(time_x,time_y,app_time.tm_hour/10%10+'0',16,1); time_x+=interval;
	gui_ShowChar(time_x,time_y,app_time.tm_hour/1%10+'0',16,1); time_x+=interval;
	gui_ShowChar(time_x,time_y,':',16,1); time_x+=interval;
	gui_ShowChar(time_x,time_y,app_time.tm_min/10%10+'0',16,1); time_x+=interval;
	gui_ShowChar(time_x,time_y,app_time.tm_min/1%10+'0',16,1); time_x+=interval;
	gui_ShowChar(time_x,time_y,':',16,1); time_x+=interval;
	gui_ShowChar(time_x,time_y,app_time.tm_sec/10%10+'0',16,1); time_x+=interval;
	gui_ShowChar(time_x,time_y,app_time.tm_sec/1%10+'0',16,1); time_x+=interval;

	
	gui_ShowChar(temp_x,temp_y,temp/100%10+'0',16,1); temp_x+=interval;
	gui_ShowChar(temp_x,temp_y,temp/10%10+'0',16,1); temp_x+=interval;
	gui_ShowChar(temp_x,temp_y,'.',16,1); temp_x+=4;
	gui_ShowChar(temp_x,temp_y,temp/1%10+'0',16,1); temp_x+=interval;
	gui_ShowChar(temp_x,temp_y-2,'o',12,1); temp_x+=6;
	gui_ShowChar(temp_x,temp_y,'C',16,1); temp_x+=interval;
	
	
	gui_ShowChar(humi_x,humi_y,humi/100%10+'0',16,1); humi_x+=interval;
	gui_ShowChar(humi_x,humi_y,humi/10%10+'0',16,1); humi_x+=interval;
	gui_ShowChar(humi_x,humi_y,'.',16,1); humi_x+=4;
	gui_ShowChar(humi_x,humi_y,humi/1%10+'0',16,1); humi_x+=interval+3;
	gui_ShowChar(humi_x,humi_y,'%',16,1); humi_x+=interval;
	
	oled_refresh(OLED_GRAM);
}

3.读取DHT11

uint8_t dht11_readData(int16_t *Temp, int16_t *Humi)
{
	uint8_t sta = 0;
	uint8_t i;
	uint8_t buf[5];
	
	if (DHT11RstAndCheck())         //检测响应信号
	{
		for(i=0;i<5;i++)
		{
			buf=DHT11ReadByte();
		}
		if(buf[0]+buf[1]+buf[2]+buf[3] == buf[4]) //校验成功
		{
		uint8_t H_inte = buf[0]; //湿度整数部分数据
		uint8_t H_frac = buf[1]; //湿度小数部分数据
		uint8_t T_inte = buf[2]; //温度整数部分数据
		uint8_t T_frac = buf[3]; //温度小数部分数据

		printf("%d.%d %d.%d %d\n",buf[0],buf[1],buf[2],buf[3],buf[4]);
		*Humi = H_inte*10+H_frac;
		*Temp = T_inte*10+T_frac;
		}
		sta = 0;
	}
	else //响应失败返回-1
	{
	*Humi = 0; //响应失败返回-1
	*Temp = 0; //响应失败返回-1
	sta = 1;
	}

	return sta;    
}

4.播放声音

void player_voice()
{
    char url[128];

    snprintf(url, sizeof(url), "mem://addr=%u&size=%u", (uint32_t)&_welcome_mp3, _welcome_mp3_len);
    player_play(get_player_demo(), url, 0);
}

5.按键检测与处理任务

static void key_task()
{
	uint8_t key1_state = 0;
	uint8_t key2_state = 0;
	uint8_t key_time;

	while(1)
	{
		if(key1_get() == 1)
		{
			aos_msleep(10);
			if(key1_state == 0) key_time = 1000 / 10;
			else key_time = 100 /10;
			while(key1_get() == 1) 
			{
				aos_msleep(10);
				key_time--;
				if(key_time == 0) break;
			}
			key1_state = 1;
		}
		else
		{
			key1_state = 0;
		}
		
		if(key2_get() == 1)
		{
			aos_msleep(10);
			if(key2_state == 0) key_time = 1000 / 10;
			else key_time = 100 /10;
			while(key2_get() == 1)
			{
				aos_msleep(10);
				key_time--;
				if(key_time == 0) break;
			}
			key2_state = 1;
		}
		else
		{
			key2_state = 0;
		}
		
		if(key1_state == 1)
		{
			screen_state ++;
		}
		if(screen_state > 4) screen_state = 0;
		
		if(key2_state == 1)
		{
			if(screen_state == 1)
				alarm_clock.tm_hour++;
			if(alarm_clock.tm_hour >= 24) alarm_clock.tm_hour = 0;
			
			if(screen_state == 2)
				alarm_clock.tm_min++;
			if(alarm_clock.tm_min >= 60) alarm_clock.tm_min = 0;
			
			if(screen_state == 3)
				alarm_clock.tm_sec++;
			if(alarm_clock.tm_sec >= 60) alarm_clock.tm_sec = 0;
			
			if(screen_state == 4)
				alarm_clock_state ++;
			if(alarm_clock_state >= 2) alarm_clock_state = 0;
		}
		
		if((key1_state == 1 || key2_state == 1)&&player_flag == 1)
		{
			player_flag = 0;
		}
		aos_msleep(50);
	}
}

六、项目总结

整体项目比较简单，论坛也有很多大神的资料参考，很顺利就完成了，总体还是很好的，就是CDK环境用起来怪怪的。

最后感谢论坛跟平头哥提供的这次机会。
