Столкнулся с проблемой, когда приобрел RDM6300 Неправильно определяет карту. Ввел вот этот код: #include <SoftwareSerial.h> // The RFID module's TX pin needs to be connected to the Arduino. Module // RX doesn't need to be connected to anything since we won't send // commands to it, but SoftwareSerial requires us to define a pin for // TX anyway so you can either connect module RX to Arduino TX or just // leave them disconnected. // If you have built the circuit exactly as described in Practical // Arduino, use pins D2 / D3: #define rxPin 2 #define txPin 3 // If you are using the Freetronics RFID Lock Shield, use pins D4 / D5: /* #define rxPin 4 */ /* #define txPin 5 */ // Create a software serial object for the connection to the RFID module SoftwareSerial rfid = SoftwareSerial( rxPin, txPin ); // Set up outputs for the strike plate and status LEDs. // If you have built the circuit exactly as described in Practical // Arduino, use pins D12 and D13: #define strikePlate 12 #define ledPin 13 // If you are using the Freetronics RFID Lock Shield, use pins D6 / D7: /* #define strikePlate 6 */ /* #define ledPin 7 */ // Specify how long the strike plate should be held open. #define unlockSeconds 2 // The tag database consists of two parts. The first part is an array of // tag values with each tag taking up 5 bytes. The second is a list of // names with one name for each tag (ie: group of 5 bytes). char* allowedTags[] = { "00005A0E17", // Tag 1 "04146E8BDD", // Tag 2 "0413BBBF23", // Tag 3 }; // List of names to associate with the matching tag IDs char* tagName[] = { "Jonathan Oxer", // Tag 1 "Hugh Blemings", // Tag 2 "Dexter D Dog", // Tag 3 }; // Check the number of tags defined int numberOfTags = sizeof(allowedTags)/sizeof(allowedTags[0]); int incomingByte = 0; // To store incoming serial data /** * Setup */ void setup() { pinMode(ledPin, OUTPUT); digitalWrite(ledPin, LOW); pinMode(strikePlate, OUTPUT); digitalWrite(strikePlate, LOW); Serial.begin(38400); // Serial port for connection to host rfid.begin(9600); // Serial port for connection to RFID module Serial.println("RFID reader starting up"); } /** * Loop */ void loop() { byte i = 0; byte val = 0; byte checksum = 0; byte bytesRead = 0; byte tempByte = 0; byte tagBytes[6]; // "Unique" tags are only 5 bytes but we need an extra byte for the checksum char tagValue[10]; // Read from the RFID module. Because this connection uses SoftwareSerial // there is no equivalent to the Serial.available() function, so at this // point the program blocks while waiting for a value from the module if((val = rfid.read()) == 2) { // Check for header bytesRead = 0; while (bytesRead < 12) { // Read 10 digit code + 2 digit checksum val = rfid.read(); // Append the first 10 bytes (0 to 9) to the raw tag value if (bytesRead < 10) { tagValue[bytesRead] = val; } // Check if this is a header or stop byte before the 10 digit reading is complete if((val == 0x0D)||(val == 0x0A)||(val == 0x03)||(val == 0x02)) { break; // Stop reading } // Ascii/Hex conversion: if ((val >= '0') && (val <= '9')) { val = val - '0'; } else if ((val >= 'A') && (val <= 'F')) { val = 10 + val - 'A'; } // Every two hex-digits, add a byte to the code: if (bytesRead & 1 == 1) { // Make space for this hex-digit by shifting the previous digit 4 bits to the left tagBytes[bytesRead >> 1] = (val | (tempByte << 4)); if (bytesRead >> 1 != 5) { // If we're at the checksum byte, checksum ^= tagBytes[bytesRead >> 1]; // Calculate the checksum... (XOR) }; } else { tempByte = val; // Store the first hex digit first }; bytesRead++; // Ready to read next digit } // Send the result to the host connected via USB if (bytesRead == 12) { // 12 digit read is complete tagValue[10] = '\0'; // Null-terminate the string Serial.print("Tag read: "); for (i=0; i<5; i++) { // Add a leading 0 to pad out values below 16 if (tagBytes < 16) { Serial.print("0"); } Serial.print(tagBytes, HEX); } Serial.println(); Serial.print("Checksum: "); Serial.print(tagBytes[5], HEX); Serial.println(tagBytes[5] == checksum ?

Может кто видит проблему?
есть кнопочка "код", такую мешанину читать никто не станет. ID карты выводит? Если оставить только Tag1, что будет?
