1.硬件平台

1.STM32F103+FM17550

2.卡片类型：身份证、TYPEA/B卡、银行卡

2.驱动实现

1.硬件SPI，配置如下

/* SPI1 init function */
static void MX_SPI1_Init(void)
{/* SPI1 parameter configuration*/hspi1.Instance = SPI1;hspi1.Init.Mode = SPI_MODE_MASTER;hspi1.Init.Direction = SPI_DIRECTION_2LINES;hspi1.Init.DataSize = SPI_DATASIZE_8BIT;hspi1.Init.CLKPolarity = SPI_POLARITY_HIGH;hspi1.Init.CLKPhase = SPI_PHASE_2EDGE;hspi1.Init.NSS = SPI_NSS_SOFT;hspi1.Init.BaudRatePrescaler = SPI_BAUDRATEPRESCALER_64;hspi1.Init.FirstBit = SPI_FIRSTBIT_MSB;hspi1.Init.TIMode = SPI_TIMODE_DISABLE;hspi1.Init.CRCCalculation = SPI_CRCCALCULATION_DISABLE;hspi1.Init.CRCPolynomial = 10;if (HAL_SPI_Init(&hspi1) != HAL_OK){Error_Handler();}}

3.循环扫卡测试程序

/*********************************************
** 函数描述：循环寻卡
** 输入参数：无
** 返回值  ：无
** 说明：
*********************************************/
void Find_Card(void)
{volatile unsigned char statues;unsigned int Rec_len;               //卡片返回数据长度statues=TypeA_CardActive(picc_atqa,picc_uid,picc_sak);if(statues != TRUE){FM175X_SoftReset();Rec_len = 0;Pcd_ConfigISOType(1);             //设置TypeBSet_Rf(3);   //turn on radiostatues=TypeB_WUP(&Rec_len,Send_Buff+Data,PUPI);//寻卡 Standard	 send request command Standard modeif(statues == TRUE)statues=TypeB_Select(PUPI,&Rec_len,Send_Buff+Data);				 }if(statues == TRUE){HAL_Delay(10);}			HAL_Delay(1000);	Set_Rf(0);   //turn off radio	
}

4.TYPEB射频卡扫描

/*************************************************
** 函数描述：测试TYPEB卡
** 输入参数：无
** 返回值  ：无
** 说明：
*************************************************/
void Test_CardB(void)
{uint8_t status;unsigned int Rec_len;               //卡片返回数据长度HAL_Delay(1000);FM175X_SoftReset();	Rec_len = 0;Pcd_ConfigISOType(1);             //设置TypeBSet_Rf(3);                        //turn on radiostatus=TypeB_WUP(&Rec_len,Send_Buff,PUPI);//寻卡 Standard	 send request command Standard modeif(Rec_len == 0x60){status=TypeB_Select(PUPI,&Rec_len,Send_Buff);if(status == TRUE){status=TypeB_GetUID(&Rec_len,Send_Buff);if(status == TRUE){junValue++;}}}
}

5.TYPEA射频卡扫描

/***********************************************************
** 函数描述：测试TYPEA卡
** 输入参数：无
** 返回值  ：无
** 说明：
***********************************************************/
void Test_CardA(void)
{uint8_t status;//激活卡（寻卡，防冲突，选卡）status=TypeA_CardActive(picc_atqa,picc_uid,picc_sak);if (status != TRUE){//激活失败return;}status=Mifare_Auth(0x00,0x01,DefualtKey,picc_uid);	//card authenticationif (status != TRUE){//认证失败return;}//测试的时候避免反复写数据if(junValue){status=Mifare_Blockwrite(0x04,DefualtData);	 //block write functionif (status != TRUE){//写数据失败return;}junValue = 0;}status=Mifare_Blockread(0x04,Send_Buff);	//bolck read function(读04块的数据)if (status != TRUE){//读数据失败return;}
}

6.身份证UID读取

//检测TYPEB 射频卡FM175X_SoftReset();	Rec_len = 0;Pcd_ConfigISOType(1);             //设置TypeBSet_Rf(3);                        //turn on radiostatus=TypeB_WUP(&Rec_len,Send_Buff,PUPI);//寻卡 Standard	 send request command Standard modeif(Rec_len == 0x60){status=TypeB_Select(PUPI,&Rec_len,Send_Buff);if(status == TRUE){status=TypeB_GetUID(&Rec_len,Send_Buff);if(status == TRUE){for(uint8_t i=0;i<12;i++){HID_SendHex(Send_Buff[i]);}HID_Enter();}}}
