DS1302时钟和RAM数据区存数据.doc

DS1302 RAM数据区存数据DS1302RAM数据区存数据，做了2天，才发现数据读写时钟不对，现在将写好的文件与大家分享，此程序已经调试过，能正常工作！DS1302头文件#ifdef DS1302_GLOBAL#define _DS1302_EXTERN #else#define _DS1302_EXTERN extern#endif#define SECR 0x81#define SECW 0x80#defineMINR 0x83#define MINW 0x82#define HRR 0x85#define HRW 0x84#define DATER 0x87#define DATEW 0x86#define MONTHR 0x89#define MONTHW 0x88#define DAYR 0x8B#define DAYW 0x8A#define YEARR 0x8D#define YEARW 0x8C#define CONTROL 0x8E#define CHANGER 0x90 #define START_DATA0xa5#define READ_START_ADR0xC1/RAM 0#define WRITE_START_ADR0xC0#define READ_RAM_START_ADR0xC3/RAM 1 -RAM 30 #define WRITE_RAM_START_ADR0xC2#define SECOND0/存秒 #define MINUTE1/存分 #define HOUR 2/存时 #define DAY3/存日 #define MONTH 4/存月 #define WEEK 5/存周 #define YEAR 6/存年 _DS1302_EXTERN unsigned char RTCTime7;/零时时间缓冲区#define SecondRTCTimeSECOND/存秒#define Minute RTCTimeMINUTE/存分#define Hour RTCTimeHOUR /存时#define Day RTCTimeDAY /存日#define Month RTCTimeMONTH /存月#define Week RTCTimeWEEK /存星期#define Year RTCTimeYEAR /存年/DAT管脚定义 #define DS1302_DAT_PatOut()P01IO = P01IOPushpullOutput/输出模式#define DS1302_DAT_PatIn()P01IO = P01IOInputMode/输入模式 #define DS1302_DATP01#define DS1302_DAT_H() DS1302_DAT = 1#define DS1302_DAT_L() DS1302_DAT = 0 /CLK管脚定义 #define DS1302_CLKP00#define DS1302_CLK_H() DS1302_CLK = 1#define DS1302_CLK_L() DS1302_CLK = 0_DS1302_EXTERN void write_byte(unsigned char da);_DS1302_EXTERN unsigned char read_byte(void);_DS1302_EXTERN void Writer1302(unsigned char ADD,unsigned char DATA);_DS1302_EXTERN unsigned char Read1302 ( unsigned char ADD );_DS1302_EXTERN void readRTC_Time(void);_DS1302_EXTERN void WriteRTC_Time(void);_DS1302_EXTERN void init_RTC(void);_DS1302_EXTERN void DS1302_Ram_read(void);_DS1302_EXTERN void Write_ram_fun(void);_DS1302_EXTERN unsigned char Hex_change_D(unsigned char i,unsigned char valule);_DS1302_EXTERN unsigned char Hour_Time;_DS1302_EXTERN unsigned char Minute_Time;/*库函数的申明与引用*/#define DS1302_GLOBAL/读写操作位#define CMD_READ0x01#define CMD_WRITE0x00/时钟 命令#define CMD_SECOND0x80/秒#define CMD_MINUTE0x82/分#define CMD_HOUR0x84/时#define CMD_DAY0x86/日#define CMD_MONTH0x88/月#define CMD_WEEK0x8A/星期 DATE#define CMD_YEAR0x8C/年#define CMD_CONTROL0x8E/控制(写保护)#define CMD_TRICKLE_CHARGE0x90/涓流充电#define CMD_CLOCK_BURST0xBE/连续读取/时钟配置常量#define CFG_CLOCK_HALT0x80/停止时钟控制位 SECONDbit7#define CFG_12_240x80/12/24小时值选择位 HOURbit7 #define CFG_AM_PM0x20/AP/PM位 HOURbit5 #define CFG_PROTECT0x80/写保护控制位 CONTROLbit7 不能写入#define CFG_UNPROTECT0x00/写保护控制位 CONTROLbit7 允许写入/涓流充电控制常量#define CFG_TC_D1R20xA5/high 1 Diode +2K Resistors #define CFG_TC_D2R80xAB/low 2 Diodes+8K Resistors #define CFG_TC_DISABLED0x00/Disabled(TCS1010 or DS=00 or RS=00)/RAM 命令#define CMD_RAM_BASE0xC0/RAM0RAM300;i-) DS1302_DAT=(da&0x01);
