收集整理的这篇文章主要介绍了
rfid1-stc11f32x
小编觉得挺不错的,现在分享给大家,帮大家做个参考.
淘宝上买了一个rfid板，
如下，左边是单片机stc11f32x，右边是rfid小板
射频小板的主控芯片是rc522，可读iso 14443 type a卡,比如s50卡，店主送了两张。简介一下s50卡吧，
注:ICC（Integrated Circuit Card）为集成电路卡，CD（Coupling Device）指读写设备
s50卡的eeprom共16扇区；每扇区4块，共64块；每块16字节，则每扇区16x4=64字节，每卡64x16=1024字节，如下
所有块统一编址，每扇区的尾块是控制块，其余为数据块，但扇区1的块0特殊一点，记录了厂家序列号之类的，只读。
本例将数据存入扇区1的块4。对某扇区进行读写需要通过密码验证，密码保存在该扇区的控制块中。
先看连线，如下，左边是单片机右边是rc522的接口，rc522支持spi i2c 串口，但是stc11f32x却没有这些接口，所以stc11f32x只能模拟spi时序与rc522通讯，模拟用的引脚是
P0.5 MF_SDA(NSS片选)
P0.6 MF_SCK(时钟)
P0.7 MF_MOSI
P4.1 MF_MISO
P2.7 MF_RST
相关单片机程序如下
void InitRc522(void)//初始化rc522 {PcdReset();PcdAntennaOff(); PcdAntennaOn();M500PcdConfigISOType( 'A' ); } void InitAll(void) {Dlms(100);InitPort();Dlms(100);InitLcd0108();InitRc522();EA=0;init_time0();uart_init();EA=1; //re-enable interrupts TimeShowMenu=0;bShowMenu=0; // bShowTime=1;bWarn=0;bPass=0;SysTime=0;KeyTime=0;KeyNum=0;bTimed=1;bMenued=0; bShowWelcome=1; TimeShowMenu=250; }void ctrlprocess(void) {float data money_value; // unsigned char ConsumedData;unsigned char data ii;char data status;status=PcdRequest(PICC_REQIDL,&RevBuffer[0]);//寻天线区内未进入休眠状态的卡，返回卡片类型 2字节if(status!=MI_OK){return;}status=PcdAnticoll(&RevBuffer[2]);//防冲撞，返回卡的序列号 4字节if(status!=MI_OK){return;}if(!bShowMenu){bShowMenu=1;//bShowWelcome=0;bTimed=0;bMenued=1; ShowMenu();}TimeShowMenu=0;//Clear88(0,5,2,8);Clear88(2,5,2,8);Clear88(4,5,2,8);//Clear88(6,5,2,8);memcpy(MLastSelectedSnr,&RevBuffer[2],4);for(ii=0;ii<4;ii++){Show816(0,5+2*ii,(MLastSelectedSnr[ii]>>4)&0x0f);Show816(0,6+2*ii,MLastSelectedSnr[ii]&0x0f);} status=PcdSelect(MLastSelectedSnr);//选卡if(status!=MI_OK){return;}if(oprationcard==REGCARD)//注册{status=PcdAuthState(PICC_AUTHENT1A,7,LastKeyA,MLastSelectedSnr);//????KUAI4?//DelayNS(1);if(status!=MI_OK){bWarn=1;return;}status=PcdWrite(7,&NewKey[0]);if(status!=MI_OK){bWarn=1;return;}for(ii=0;ii<16;ii++){Write_First_Data[ii]=0xaa;}status=PcdWrite(4,&Write_First_Data[0]);if(status!=MI_OK){bWarn=1;return;}bPass=1; PcdHalt(); }else if(oprationcard==READCARD)//读卡{status=PcdAuthState(PICC_AUTHENT1A,7,NewKeyA,MLastSelectedSnr);//????KUAI4?if(status!=MI_OK){return;}status=PcdRead(4,Read_Data);if(status!=MI_OK){bWarn=1;return;}for(ii=0;ii<16;ii++){Write_First_Data[ii]=0xaa;}status=PcdWrite(4,&Write_First_Data[0]);for(ii=0;ii<4;ii++){fltchr.chr[ii]=Read_Data[ii];sendchar1(fltchr.chr[ii]);} //ShowFloat816(4,5,fltchr.flt); ShowFloat816(4,5,fltchr.flt); if(fltchr.flt<0){bWarn=1;} bPass=1;PcdHalt(); }else if(oprationcard==CONSUME)//消费{status=PcdAuthState(PICC_AUTHENT1A,7,NewKeyA,MLastSelectedSnr);//????KUAI4?if(status!=MI_OK){return;}status=PcdRead(4,Read_Data);if(status!=MI_OK){bWarn=1;return;}for(ii=0;ii<4;ii++) //{fltchr.chr[ii]=Read_Data[ii];sendchar1(fltchr.chr[ii]);}money_value=fltchr.flt;if(money_value<-100){money_value=-100;}if(money_value<0){money_value+=100;}fltchr.flt=money_value-2.5;for(ii=0;ii<4;ii++){Write_Consume_Data[ii]=fltchr.chr[ii];}status=PcdWrite(4,&Write_Consume_Data[0]);for(ii=0;ii<4;ii++) {sendchar1(fltchr.chr[ii]);}if(status!=MI_OK){bWarn=1;return;} ShowFloat816(2,5,2.58);ShowFloat816(4,5,fltchr.flt); if(fltchr.flt<0){bWarn=1;} else{ bPass=1;}PcdHalt(); }else if(oprationcard==ADDMONEY)//充值{status=PcdAuthState(PICC_AUTHENT1A,7,NewKeyA,MLastSelectedSnr);//????KUAI4?if(status!=MI_OK){return;}status=PcdRead(4,Read_Data);if(status!=MI_OK){bWarn=1;return;}for(ii=0;ii<4;ii++){fltchr.chr[ii]=Read_Data[ii];}money_value=fltchr.flt;if(money_value<-100){money_value=-100;}if(money_value<0){money_value+=100;}fltchr.flt=money_value+50;for(ii=0;ii<4;ii++){Write_Consume_Data[ii]=fltchr.chr[ii];}//status=PcdWrite(4,&Write_Consume_Data[0]);for(ii=0;ii<16;ii++) //向块4写入初始数值{Write_First_Data[ii]=0xaa;}status=PcdWrite(4,&Write_First_Data[0]); //if(status!=MI_OK){bWarn=1;return;} ShowFloat816(2,5,50.00);ShowFloat816(4,5,fltchr.flt); bPass=1;PcdHalt(); }/*else{status=PcdAuthState(PICC_AUTHENT1A,7,NewKeyA,MLastSelectedSnr);//????KUAI4?if(status!=MI_OK){return;}status=PcdRead(4,Read_Data);if(status!=MI_OK){return;}for(ii=0;ii<4;ii++){fltchr.chr[ii]=Read_Data[ii];} ShowFloat816(4,5,fltchr.flt); PcdHalt(); }*/ }void Warn(void) {uchar data ii;for(ii=0;ii<3;ii++){SET_BEEP;delay_ms(120);CLR_BEEP;delay_ms(120);} }void main(void) {InitAll();//其中调用InitRc522()，通过模拟spi输出数据初始化rfid模块#pragma ASMSETB P3.5NOP#pragma ENDASM oprationcard=CONSUME;//刚一上电，是消费模式。之后通过按键可以改变模式，并保存在oprationcard变量中while(1){KeyNum=GetKey();// sendchar1(1);if(bMenued){if( (KeyNum==N_1)&&(!KeyTime) )//if(!keytime)<=>if(keytime==0) //当第一次按下k1时，keytime=0，所以执行之//当第二次按下k1时, 如果此时距第一次按下k1的时间在15个time溢出周期内，不会执行之。否则执行之，{KeyTime=15;TimeShowMenu=0; //卡片放在上面，从没有任何按键操作算起，超过250个time溢出周期，则会进入welcom页面，相当于待机时间oprationcard=CONSUME;sendchar1(KeyNum);ShowHZ1616(2,0,4); //消 ShowHZ1616(2,2,5); //费 }else if( (KeyNum==N_2)&&(!KeyTime) ){KeyTime=15;TimeShowMenu=0;oprationcard=ADDMONEY;sendchar1(KeyNum);ShowHZ1616(2,0,6); //充值 ShowHZ1616(2,2,7); // }else if( (KeyNum==N_3)&&(!KeyTime) ){KeyTime=15;TimeShowMenu=0;oprationcard=REGCARD;sendchar1(KeyNum);ShowHZ1616(2,0,10); //注册 ShowHZ1616(2,2,11); // } else if( (KeyNum==N_4)&&(!KeyTime) ){KeyTime=15;TimeShowMenu=0;oprationcard=READCARD;sendchar1(KeyNum);// sendchar1(55);ShowHZ1616(2,0,12); //读卡ShowHZ1616(2,2,13); // } } if(bShowWelcome){bShowWelcome=0;bTimed=1;bMenued=0;ShowWelcome(); }if(bWarn){bWarn=0;Warn();}if(bPass){bPass=0;Pass();}ctrlprocess();//rc522寻卡读写等函数} }
