光耦中间继电器控制加热设备: 实操2

武汉芯源半导体有限公司技术提供有大量中文标注的实验例程和固件库，在此基础上很容易编程制作产品。

准备利用【CW32饭盒派开发板试用体验】光耦中间继电器控制加热设备: 实操1为基础（系统时钟配置为64M，AD电位器所用IO口：PB0，OLED屏幕显示AD电压值，V为单位，RTOS，KEY，LED和UART）。增加RTC，KEY，输入输出调试信息。

1. 增加RTC

在RCC_Configuration(void)中增加

/* 4. RTCÊ±ÖÓ */
	  RCC_LSI_Enable();
	RCC_LSE_Enable(RCC_LSE_MODE_OSC, RCC_LSE_AMP_NORMAL, RCC_LSE_DRIVER_NORMAL);
  RCC_APBPeriphClk_Enable1(RCC_APB1_PERIPH_RTC, ENABLE);

程序中增加初始化及中断程序

UART_init();	
 /* USER CODE BEGIN 2 */
  printf("RTC Init...\r\n");	
  printf("    (RTC CR0:%04x,CR1:%04x,CR2:%04x,RESET FLAG:0x%08x)\r\n",CW_RTC->CR0,CW_RTC->CR1,CW_RTC->CR2,CW_SYSCTRL->RESETFLAG);	
	
  //RCC_HSE_Enable(RCC_HSE_MODE_OSC, RCC_HSE_FREQ_GT24M,RCC_HSE_DRIVER_NORMAL, RCC_HSE_FLT_CLOSE);  //Ñ¡ÔñHSEÎªRTCÊ±ÖÓ
  RCC_LSE_Enable(RCC_LSE_MODE_OSC, RCC_LSE_AMP_NORMAL, RCC_LSE_DRIVER_NORMAL);  // Ñ¡ÔñLSEÎªRTCÊ±ÖÓ
  //RCC_LSI_Enable();                                                           // Ñ¡ÔñLSIÎªRTCÊ±ÖÓ
	
//	RTC_InitStruct.DateStruct.Day = 0x21;             //ÉèÖÃÈÕÆÚ£¬DAY¡¢MONTH¡¢YEAR±ØÐëÎªBCD·½Ê½£¬ÐÇÆÚÎª0~6£¬´ú±íÐÇÆÚÈÕ£¬ÐÇÆÚÒ»ÖÁÐÇÆÚÁù
	RTC_InitStruct.DateStruct.Year = 0x23;
	RTC_InitStruct.DateStruct.Month = RTC_Month_June; 
	RTC_InitStruct.DateStruct.Day = 0x09;  
	RTC_InitStruct.DateStruct.Week = RTC_Weekday_Friday;

	printf("-------Set Date as 20%x/%x/%x\r\n", RTC_InitStruct.DateStruct.Year,RTC_InitStruct.DateStruct.Month,RTC_InitStruct.DateStruct.Day);
	
	RTC_InitStruct.TimeStruct.Hour = 0x9;         //ÉèÖÃÊ±¼ä£¬HOUR¡¢MINIUTE¡¢SECOND±ØÐëÎªBCD·½Ê½£¬ÓÃ»§Ðë±£Ö¤HOUR¡¢AMPM¡¢H24Ö®¼äµÄ¹ØÁªÕýÈ·ÐÔ
	RTC_InitStruct.TimeStruct.Minute = 0x58;
	RTC_InitStruct.TimeStruct.Second = 0x59;	
  RTC_InitStruct.TimeStruct.AMPM = 1;
  RTC_InitStruct.TimeStruct.H24 = 0;
	printf("-------Set Time as %02x:%02x:%02x\r\n", RTC_InitStruct.TimeStruct.Hour,RTC_InitStruct.TimeStruct.Minute,RTC_InitStruct.TimeStruct.Second);
  RTC_InitStruct.RTC_ClockSource = RTC_RTCCLK_FROM_LSE;
  RTC_Init(&RTC_InitStruct);    //  ÓÃ»§ÐèÑ¡¶¨ÐèÒªÊ¹ÓÃµÄÊ±ÖÓÔ´	

	printf("=====Set interval period as 0.5s...\r\n");	  
  RTC_SetInterval(RTC_INTERVAL_EVERY_1M);//RTC_INTERVAL_EVERY_0_5S
	
	/* ÉèÖÃÄÖÖÓÎª¹¤×÷ÈÕÉÏÎçµÄ6£º45 */
  printf("=====Set AlarmA at 6:45 on workday...\r\n");	
	
	RTC_AlarmStruct.RTC_AlarmMask = RTC_AlarmMask_WeekMON | RTC_AlarmMask_WeekTUE |
	                                RTC_AlarmMask_WeekWED | RTC_AlarmMask_WeekTHU |
																	RTC_AlarmMask_WeekFRI;
	RTC_AlarmStruct.RTC_AlarmTime.Hour = 6;
	RTC_AlarmStruct.RTC_AlarmTime.Minute = 0x45;
	RTC_AlarmStruct.RTC_AlarmTime.Second = 0;
	RTC_SetAlarm(RTC_Alarm_A, &RTC_AlarmStruct);
	RTC_AlarmCmd(RTC_Alarm_A, ENABLE);  
	
  printf("=====Enable ALRAMA and INTERVAL IT...\r\n");		
	
	RTC_ITConfig(RTC_IT_ALARMA | RTC_IT_INTERVAL, ENABLE);
  __disable_irq(); 
  NVIC_EnableIRQ(RTC_IRQn); 
  __enable_irq();

void ShowTime(void)
{
  RTC_TimeTypeDef RTC_TimeStruct;
	RTC_DateTypeDef RTC_DateStruct;
	static uint8_t *WeekdayStr[7]={"SUN","MON","TUE","WED","THU","FRI","SAT"};
	static uint8_t *H12AMPMStr[2][2]={{"AM","PM"},{"",""}};
	
	RTC_GetDate(&RTC_DateStruct);	
	RTC_GetTime(&RTC_TimeStruct);	
	
  printf(".Date is 20%02x/%02x/%02x(%s).Time is %02x%s:%02x:%02x\r\n", RTC_DateStruct.Year, RTC_DateStruct.Month, RTC_DateStruct.Day, WeekdayStr[RTC_DateStruct.Week], RTC_TimeStruct.Hour, H12AMPMStr[RTC_TimeStruct.H24][RTC_TimeStruct.AMPM],RTC_TimeStruct.Minute, RTC_TimeStruct.Second);
}

void RTC_IRQHandler(void)
{
  if (RTC_GetITState(RTC_IT_ALARMA))
	{
		RTC_ClearITPendingBit(RTC_IT_ALARMA);		
		printf("*********Alarm!!!!\r\n");
	}
	if (RTC_GetITState(RTC_IT_INTERVAL))
	{
		RTC_ClearITPendingBit(RTC_IT_INTERVAL);
		ShowTime();
		
	}
}

2. 增加KEY，输入输出调试信息。
**
UART3输入信息部分增加scanf 解析

#define DEBUG_USING_UART3
typedef struct
{
	boolean_t recv_flag;
	uint8_t data;
} uart_recv_t;

uart_recv_t uart3_recv_sta;

#ifdef DEBUG_USING_UART1
USART_Init(CW_UART1, &USART_InitStructure);
#elif defined DEBUG_USING_UART2
USART_Init(CW_UART2, &USART_InitStructure);
#elif defined DEBUG_USING_UART3
USART_Init(CW_UART3, &USART_InitStructure);


//??UARTx RC??//Ê¹ÄÜUARTx RCÖÐ¶Ï
USART_ITConfig(CW_UART3, USART_IT_RC, ENABLE);
//???,??????//ÓÅÏÈ¼¶£¬ÎÞÓÅÏÈ¼¶·Ö×é
NVIC_SetPriority(UART3_IRQn, 0);
//UARTx????//UARTxÖÐ¶ÏÊ¹ÄÜ
NVIC_EnableIRQ(UART3_IRQn);


#endif
void UART3_IRQHandler(void)
{
	if(USART_GetITStatus(CW_UART3, USART_IT_RC) != RESET)
	{ 
		USART_ClearITPendingBit(CW_UART3, USART_IT_RC); 
		uart3_recv_sta.data = USART_ReceiveData_8bit(CW_UART3);
		uart3_recv_sta.recv_flag = TRUE;
	}
}
int fgetc(FILE *f) 
{	
	(void)f;

	while (FALSE == uart3_recv_sta.recv_flag) {};
	uart3_recv_sta.recv_flag = FALSE;
	
	return (int)uart3_recv_sta.data;
}

3. 变更显示内容

Gui_DrawFont_GBK16(10,47,BLACK,GRAY0,"³ÌÐò");
	Gui_DrawFont_GBK16(45,47,BLACK,GRAY0,"(  )");
	Gui_DrawFont_GBK16(0,70,WHITE,RED,"¡æTEST:\n");
	Gui_DrawFont_GBK16(0,95,WHITE,RED,"µçÑ¹VOL:");
						temp=(float)adcvalue*(3.3/4096);       //µçÑ¹Öµ»»Ëã
					  sprintf(temp_buff1,"%0.2f V ",temp);
						Gui_DrawFont_GBK16(80,95,WHITE,RED,temp_buff1);
	sprintf(temp_buff1,"%02x/%02x", RTC_DateStruct.Month, RTC_DateStruct.Day);
	Gui_DrawFont_GBK16(4,115,WHITE,RED,temp_buff1);
	sprintf(temp_buff1,"%02x:%02x:%02x",RTC_TimeStruct.Hour, RTC_TimeStruct.Minute, RTC_TimeStruct.Second);
	Gui_DrawFont_GBK16(65,115,WHITE,RED,temp_buff1);
