3. Demonstration Here we show how to read RFID information using the Grove - 125KHz RFID Reader. Connect Grove - 125KHz RFID Reader to UART of Grove - Base Shield. 3.
} void loop() { if (SoftSerial.available()) // if date is coming from software serial port ==> data is coming from SoftSerial shield { while(SoftSerial.available()) // reading data into char array { buffer[count++]=SoftSerial.read(); // writing data into array if(count == 64)break; } Serial.
3.2 Wiegand Mode (Jumper Set to the Right two Pins) You would need to select the jumper to "W" to enter this mode. The Wiegand demo code for Seeeduino is designed to read Wiegand data in interrupt mode. In Wiegand Mode, output data is formatted with 26bits including 24bits card info and 2 bits parity. bi 0 1 2 3 4 5 6 7 8 9 t - P 1 1 1 1 1 1 1 1 1 1 2 2 2 2 2 2 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 D P E 0 - - E - - D2[7..0] 0 D1[7..0] D0[7..
