单片机软件解码(PT2240)说明如下：利用及：选用作为软件解码芯片：单片机时钟频率选用外部晶振：选用外部中断脚作为编码信号脚输入脚：可解芯片（脚的学习型编码芯片编码地址位：的次方重复几率万分之一）：功能有：遥控器学习（上的作为学习按纽）清除记忆（长按上的即可清除遥控器地址的记忆）：学习遥控器数量可以设定（可根据的大小随便设定）：输出功能（有三路是单击遥控器双稳，可以通过上的可以看到结果还有一路是双击遥控器双稳）：可选用的饿超再生超外差接收模块：过几天将公布的单片机软件解码资料/*/* 遥控器接收程序 */*/#include #include #define remote_geshu 10 /*/union BIT_16int TIMER1_REG;unsigned char REG2;union BIT_32unsigned long data_temp_long;unsigned char data_temp_byte4;/*/static union BIT_16 TIMER1_TEMP;/16位定时器1static union BIT_32 data_temp;/*/static volatile unsigned char rec_status 97;static unsigned char data_cout;/接收的遥控器码位数static unsigned char data;/接收的4位数据static unsigned int h_pulse;/高电平宽度static unsigned int l_pulse;/低电平宽度static unsigned char remote_cout;/遥控器数量static unsigned char remote_numb;/遥控器编号/*/static unsigned char TIMER15S1;/清除学习码按键长按时间static unsigned char TIMER15S2;/学习等待时间static unsigned char TIMER15S3;/遥控器数据缓冲时间static unsigned char TIMER15S4;/LED显示时间static unsigned char TIMER15S5;/static unsigned char TIMER15S6;/static unsigned char TIMER15S7;/static unsigned char TIMER15S8;/*/static bit head (unsigned)(&rec_status)*8+(0);/同步头标志位static bit learn (unsigned)(&rec_status)*8+(1);/学习标志位static bit recieved (unsigned)(&rec_status)*8+(2);/接收完成标志位static bit remote_button_status (unsigned)(&rec_status)*8+(3);/遥控器按键标志位static bit first_click_status (unsigned)(&rec_status)*8+(4);/遥控器按键单击标志位/*/* 数据接收 */*/unsigned char data_read(void)if(h_pulsel_pulse)if(l_pulse200)&(l_pulse1000)if(h_pulse(l_pulse200)&(h_pulse1000)if(l_pulse(h_pulse2)return 0;/数据为0return 2;/无效的数据/*/void clr_head(void)/清除寄存器data_cout=0;head=0; /*/#pragma interrupt_level 1void check_data(void)/检测数据是否正确if(head)switch(data_read()case 0:(data_temp.data_temp_long)=1;data_cout+;break;case 1:(data_temp.data_temp_long)23)INTE=0;recieved=1;clr_head();/*/#pragma interrupt_level 1void check_head(void)if(!head)&(!recieved)/if(h_pulse300)&(h_pulseh_pulse*27)&(l_pulse head=1;/*/#pragma interrupt_level 1void interrupt level_h_l(void)/* if(RAIF)/如果是电平中断PORTA=PORTA;RAIF=0;/TIMER1_TEMP.REG0=TMR1L;TIMER1_TEMP.REG1=TMR1H;TMR1H=0;TMR1L=0;if(RA4)/如果是低电平中断l_pulse=TIMER1_TEMP.TIMER1_REG;check_data();check_head();else/如果是高电平中断h_pulse=TIMER1_TEMP.TIMER1_REG;*/if(INTF)INTF=0;TIMER1_TEMP.REG0=TMR1L;TIMER1_TEMP.REG1=TMR1H;TMR1H=0;TMR1L=0;if(INTEDG)/低电平宽度INTEDG=0;l_pulse=TIMER1_TEMP.TIMER1_REG;check_data();check_head();elseINTEDG=1;h_pulse=TIMER1_TEMP.TIMER1_REG;if(T0IF)/T0IF=0;TIMER15S1+;TIMER15S2+;TIMER15S3+;TIMER15S4+;TIMER15S5+;TIMER15S6+;TIMER15S7+;TIMER15S8+;/*/* 遥控器学习 */*/void clr_learn_reg(void)unsigned char n;di();for(n=1;n=remote_cout*4;n+)eeprom_write(n,0);eeprom_write(70,0);eeprom_write(71,0);ei();/*/unsigned char compare_data(unsigned char eep_addr)unsigned char n;union BIT_32 addr_data; for(n=0;n20)remote_cout=0; /如果EEPROM是空的则为0/*/void check_learn_pro(void)unsigned char n;if(learn)learn=0;remote_numb=eeprom_read(70);/读出现在可以覆盖掉哪个遥控器的编号read_remote_cout();/读遥控器的数量if(remote_numb(remote_geshu-1)remote_numb=0;/如果遥控器的编号已经是最大的了 则从小开始if(remote_cout=0)|!compare_all_data()/如果还没有遥控器学习或没有相同地址的遥控器学习di();for(n=0;n30)/是否长按了3秒learn=0;/clr_learn_reg();RC4=0;elselearn=1;/TIMER15S2=0;TIMER15S4=0;RC4=1;elseTIMER15S1=0;if(TIMER15S260)learn=0;/if(TIMER15S32)/数据保持时间data=0;TIMER15S3=0;if(TIMER15S43)/LED显示时间RC4=0;if(recieved)TIMER15S3=0;recieved=0;TIMER15S4=0;RC4=1;check_learn_pro();check_out_pro(); INTE=1;/*/* 控制部分程序 */*/void control_init(void);/*/*声音部分程序*/*/*/unsigned char delay(unsigned int nus)for(;nus0;nus-)if(recieved=1) return 0;asm(nop);/*/unsigned char soud_one_fre(unsigned int cout,unsigned int delay_time)/发音程序if(recieved=1) return 0;INTE=0;for (;cout0;cout-)RC6=!RC6;delay(delay_time);RC6=0;INTE=1;/*/*急促的声音*/*/unsigned char soud_one_fre0(unsigned int time,unsigned int delay_time)for (;time0;time-)if(recieved=1) return 0;soud_one_fre(1000,10);delay(delay_time);/*/*救护的声音*/*/unsigned char soud_tow_fre0(unsigned int time)/for (;time0;time-)if(recieved=1) return 0;soud_one_fre(900,10);soud_one_fre(800,30);/*/*低-高音*/*/unsigned char soud_many_fre0(unsigned int time,unsigned int cout)for (;time0;time-)unsigned int delay_time;for(delay_time=50;delay_time10;delay_time-)if(recieved=1) return 0;soud_one_fre(cout,delay_time
