基于MSP430的多功能数字时钟C程序设计

硬件连接图源程序如下/主程序/功能1、KEY1循环选择设置时间模式和设置闹钟模式。选择设置时间模式时P23口灯亮，选择设置闹钟模式时P27口的灯亮。KEY2按下退出模式选择，同时进入时间/闹钟设置，按KEY1小时位加，按KEY2分钟位加。2、KEY3按下退出时间/闹钟设置，同时显示温度，循环按KEY3可切换温度与时间的显示。3、未进入设置模式状态时，KEY2可循环选择闹钟的开启和关闭。注在闹钟设置状态下，时钟并没有停止，是不停的走动的。且在时间走动显示过程中，小时和分钟之间的分隔符号每秒闪烁次。小时进制。/INCLUDE“MSP430X14XH“INCLUDE“LCD1602H“/DS18B20端口DEFINEOUT_DS18B20_0P6OUTCHARDISPALY32/CHARP_KEY1255CHARN_KEY1255CHARP_KEY2255CHARN_KEY2255CHARP_KEY3255CHARN_KEY3255CHARCOUNT10CHARCOUNT20CHARMODE0DEFINEPUSH_KEY11DEFINEPUSH_KEY22DEFINEPUSH_KEY33DEFINEKEY1_INP1INCHARKEY_INDEXW0CHARKEY_INDEXR0CHARKEY_COUNT0VOIDKEY_INBUFFCHARKEYCHARGETKEYVOIDSCAN_IOVOIDDELAY_MSUNSIGNEDDLYINTI,JFORI0I12WRITE_CHARPWRITE_CHARMWRITE_CHARLCD1602_DISP_BYTEHOURIFCOUNT20WRITE_CHARIFCOUNT21WRITE_CHARLCD1602_DISP_BYTEMINLCD1602_DISP_SPACEVOIDDISPLAYCLKP4OUT0X80ORDERIFCLKHOUR12WRITE_CHARPWRITE_CHARMWRITE_CHARLCD1602_DISP_BYTECLKHOURWRITE_CHARLCD1602_DISP_BYTECLKMINLCD1602_DISP_SPACE/VOIDKEY_INBUFFCHARKEY/键盘部分程序IFKEY_COUNTKEY_BUFFSIZERETURN_DINTKEY_COUNTKEY_BUFFKEY_INDEXWKEYIFKEY_INDEXWKEY_BUFFSIZEKEY_INDEXW0_EINTCHARGETKEYCHARKEYIFKEY_COUNT0RETURN0_DINTKEY_COUNTKEYKEY_BUFFKEY_INDEXRIFKEY_INDEXRKEY_BUFFSIZEKEY_INDEXR0_EINTRETURNKEYVOIDSCAN_IOP_KEY1N_KEY1N_KEY1KEY1_INP_KEY2N_KEY2N_KEY2KEY2_INP_KEY3N_KEY3N_KEY3KEY3_INIFP_KEY10IFP_KEY20IFP_KEY30PRAGMAVECTORWDT_VECTOR_INTERRUPTVOIDWDT_ISRVOIDSCAN_IO/VOIDDS18B20_IO_SETVOIDP6SEL/DS18B20延时VOIDDS1820_DELAYINTIWHILEI/长延时VOIDDELAYINTSUNSIGNEDINTI,JFORI0I1OUT_DS18B20_1DS18B20_INIFP6INDS1820_DELAY4DS18B20_OUTDS1820_DELAY50RETURNTEMP/DS18B20写操作函数VOIDDS18B20_WRITECHARDATECHARIDS18B20_OUTFORI0I1DS1820_DELAY8/DS18B20温度转换函数VOIDDS18B20CONVERTVOIDDS18B20_RESETDS18B20_WRITE0XCC/DS18B20_SKIP_ROMDS18B20_WRITE0X44/DS18B20_CONVERT_TEMDELAY200DS18B20_RESETDS18B20_WRITE0XCC/DS18B20_SKIP_ROMDS18B20_WRITE0XBE/DS18B20_READ_RAMTEMP_DATA0DS18B20_READ/先读转换结果的低八位TEMP_DATA1DS18B20_READ/读转换结果的高八位/温度换算处理VOIDWORK_TEMPCHARN0IFTEMP_DATA1127TEMP_DATA1256TEMP_DATA1/负值TEMP_DATA0256TEMP_DATA0N1DISPALY6TEMP_DATA0IQ0/延时，等待XT2起振WHILEIFG1/判断XT2是否起振BCSCTL2SELM1SELS/MCLK,SMCLK时钟为XT2/VOIDDS18B20_IO_SETVOIDP6SEL/DS18B20延时VOIDDS1820_DELAYINTIWHILEI/长延时VOIDDELAYINTSUNSIGNEDINTI,JFORI0I1OUT_DS18B20_1DS18B20_INIFP6INDS1820_DELAY4DS18B20_OUTDS1820_DELAY50RETURNTEMP/DS18B20写操作函数VOIDDS18B20_WRITECHARDATECHARIDS18B20_OUTFORI0I1DS1820_DELAY8/DS18B20温度转换函数VOIDDS18B20CONVERTVOIDDS18B20_RESETDS18B20_WRITE0XCC/DS18B20_SKIP_ROMDS18B20_WRITE0X44/DS18B20_CONVERT_TEMDELAY200DS18B20_RESETDS18B20_WRITE0XCC/DS18B20_SKIP_ROMDS18B20_WRITE0XBE/DS18B20_READ_RAMTEMP_DATA0DS18B20_READ/先读转换结果的低八位TEMP_DATA1DS18B20_READ/读转换结果的高八位/温度换算处理VOIDWORK_TEMPCHARN0IFTEMP_DATA1127TEMP_DATA1256TEMP_DATA1/负值TEMP_DATA0256TEMP_DATA0N1DISPALY6TEMP_DATA0DISPALY5DISPALY6/100/百位DISPALY4DISPALY6100/DISPALY2DISPALY4/10/十位DISPALY1DISPALY410/个位SWITCHTEMP_DATA0BREAKCASE0X0EDISPALY09BREAKCASE0X0DDISPALY08BREAKCASE0X0CDISPALY08BREAKCASE0X0BDISPALY07BREAKCASE0X0ADISPALY06BREAKCASE0X09DISPALY06BREAKCASE0X08DISPALY05BREAKCASE0X07DISPALY04BREAKCASE0X06DISPALY04BREAKCASE0X05DISPALY03BREAKCASE0X04DISPALY03BREAKCASE0X03DISPALY02BREAKCASE0X02DISPALY01BREAKCASE0X01DISPALY01BREAKCASE0X00DISPALY01BREAKDEFAULTBREAKIFN/负值时显示AA,正直显示DDDISPALY311/ELSEDISPALY310/LCD1602CINCLUDE“MSP430X14XH“DEFINESETXP6OUT|XDEFINECLRXP6OUTVOIDINIT_LCD1602VOIDLCD1602_DISP_BYTEUNSIGNEDCHARNUM/可以显示VOIDLCD1602_DISP_SPACEVOIDWRITE_CHARCHARCHVOIDORDERVOIDDATAVOIDDELAYVOIDINIT_LCD1602P6DIR|BIT4BIT5BIT6P4DIR0XFFP4OUT0X01ORDERP4OUT0X38ORDERP4OUT0X0CORDERP4OUT0X06ORDER/P4OUT0X80/ORDERVOIDLCD1602_DISPNUMCHARPTRCHARDISP_BUFF4CHARI,CHFORI0I4IDISP_BUFFIPTRPTRP4OUT0X80ORDERCHDISP_BUFF3IFCH11WRITE_CHARLCD_TABCHCHDISP_BUFF2WRITE_CHARLCD_TABCHCHDISP_BUFF1WRITE_CHARLCD_TABCHWRITE_CHARCHDISP_BUFF0WRITE_CHARLCD_TABCHWRITE_CHARWRITE_CHARCFORI0I9IWRITE_CHARP4OUT0XC0ORDERFORI0I16IWRITE_CHARVOIDLCD1602_DISP_BYTEUNSIGNEDCHARNUMUNSIGNEDCHARDISP_BUFF2UNSIGNEDCHARI,CHFORI0I2IDISP_BUFFINUM10NUMNUM/10/P4OUT0X80/ORDERCHDISP_BUFF1WRITE_CHARLCD_TABCHCHDISP_BUFF0WRITE_CHARLCD_TA
