实验目的
- 了解IAR开发环境的应用
- 熟悉MFRC531的使用
实验环境
- 硬件： RFID射频模块，USB仿真器，PC机。
- 软件：IAR Embedded Workbench for STMicroelectronics STM8 1.30 Evaluation
实验内容
- 用IAR环境，在电子标签卡片接触RFID模块时，按KEY按键，电子标签中的数据加1和减1，即充值1和减去1，可通过PC机串口软件观测。
- 在串口软件界面输出卡号、余额、小组成员所有学号。
实验步骤
实验代码
1) 输出
- 此次实验的输出为字符串形式，所以注释掉UART2_SendString()函数，避免输出乱码，三个printf()函数分别输出打印卡ID号、按键提示和余额显示。
if(MI_OK == status)
{
tx_buf[9] = money[3];
tx_buf[10] = money[2];
tx_buf[11] = money[1];
tx_buf[12] = money[0];
//UART2_SendString(tx_buf, 14);
}
else
{
Flag = 0;
}
printf("ID: %x %x %x %x\n", g_cSNR[0],g_cSNR[1],g_cSNR[2],g_cSNR[3]);
printf("please press the key,\n");
printf("value: %x %x %x %x\n",tx_buf[9],tx_buf[10],tx_buf[11],tx_buf[12]);
2) 按键控制
- 在中断处理中，判断是否PC1引脚触发，若是，则设置不接收中断，将rx_buf设置为CC EE FE 01 01 00 00 00 01 FF，其中，CC EE FE 01为固定的，第二个01为充值命令，00 00 00 01为充值金额，FF表示结束，然后将两个flag置为1（flag为0，表示未识别到卡，为1，表示识别到卡），打开中断接收信号。
INTERRUPT_HANDLER(EXTI_PORTC_IRQHandler, 5)
{
/* In order to detect unexpected events during development,
it is recommended to set a breakpoint on the following instruction.
*/
if ((GPIO_ReadInputData(GPIOC) & GPIO_PIN_1) == 0x00)//判断是否PC1引脚触发
//实现按键控制
{
disableInterrupts();
rx_buf[0] = 0xCC;
rx_buf[1] = 0xEE;
rx_buf[2] = 0xFE;
rx_buf[3] = 0x01;
rx_buf[4] = 0x01;
rx_buf[5] = 0x00;
rx_buf[6] = 0x00;
rx_buf[7] = 0x00;
rx_buf[8] = 0x01;
rx_buf[9] = 0xFF;
Uart_RecvFlag = 1;
Flag=1;
enableInterrupts();
}
}
3) 蜂鸣声响
- 读取串口指令完成后，蜂鸣器响100ms。
BEEP_On();
delay_ms(100);
BEEP_Off();
硬件连接
- 把RFID模块插到实验箱的主板上的串口
- 把ST-Link配合JTAG仿真器插到标有ST-Link标志的串口上
- 把仿真器一端的USB线插到PC机的USB端口，通过主板上的“加”“减”按键调整要实验的RFID模块（会有黄色LED灯提示），硬件连接完毕。
编译、烧录并测试
- 我们用IAR SWSTM8 1.30软件，打开..\RFID_电子钱包实验\Project\MFRC531_ATM8.eww。
- 工程编译:点击“Project”->“Rebuild All”。
- 点击“Rebuild All”进行编译。
- 将卡片放在烧录板上，把程序烧到模块里，点击“ ”中间的Download and Debug进行烧录，完成后听到蜂鸣器响一声。
- 关闭上述已打开程序，打开串口测试软件，将传感器模块连接到串口转USB模块上，将USB2UART模块的USB线连接到PC机的USB端口，然后打开串口工具，配置好串口，波特率115200，8个数据位，一个停止位，无校验位，串口开始工作。
实验结果
截图1
-
输出“ID：2d d8 49 50”，这是卡序列号；输出“please press the key”，提醒按下按键，输出“value:0 0 0 1”，此时，卡内余额（十六进制）为1，随后，每按下一次按键，向卡内充值1单位的钱，因此，后面输出的value值分别为0 0 0 2、0 0 0 3、0 0 0 4和0 0 0 5。
按键充值截图1
截图2
-
输出“ID：fd d3 71 51”，这是卡序列号；输出“please press the key”，提醒按下按键，输出“value:af b7 e3 6a”，此时，卡内余额（十六进制）为af b7 e3 6a，随后，每按下一次按键，向卡内充值1单位的钱，因此，后面输出的value值分别为af b7 e3 6b、af b7 e3 6c、af b7 e3 6d。
