I tested the example codes and the first one on the development webpage, the "Basic Example," doesn't work because it makes a call to an "authenticateBlock" function that doesn't exist in the RFID API. Therefore, I tried the "Read All Blocks" example code and once again, the output was:
For the sake of convenience, I've posted the code for Basic Example and Read All Blocks below
Basic ExampleCode:
// stores the 16 bytes data to be written in a block:
blockData writeData = {0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07,
0x08, 0x09, 0x0A, 0x0B, 0x0C, 0x0D, 0x0E, 0x0F};
// stores the 16 bytes data read from a block:
blockData readData;
// stores the key or password:
uint8_t keyAccess[] = {0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF };
// stores the block address:
uint8_t address = 0x04;
// stores the UID (unique identifier) of a card:
CardIdentifier CardID;
// stores the answer to request:
uint8_t ATQ[2];
void setup()
{
USB.begin();
USB.println("RFID/NFC @ 13.56 MHz module started");
// switchs on the RFID/NFC @ 13.56 MHz module, type B, and asigns the socket
RFID13.ON(SOCKET0, B);
delay(1000);
}
void loop()
{
USB.print("\n");
USB.println("Ready to read...");
// get the UID
RFID13.init(CardID, ATQ);
USB.print("\n");
USB.print("the Card UID: ");
RFID13.print(CardID, 4);
// auntenticate block number 4 with its access key (2nd sector)
if (!RFID13.authenticateBlock(address, keyAccess))
{
USB.println("Authentication failed");
}
else // success
{
USB.println("Authentication OK");
// after authentication, write blockData in the block
if (!RFID13.writeData(address, writeData))
{
USB.println("Write failed");
}
else // success
{
USB.println("Write block OK");
// read from address after write
if (!RFID13.readData(address, readData))
{
USB.println("Read failed");
}
else // success
{
USB.println("Read block OK");
USB.print("Data read: ");
RFID13.print(readData, 16);
}
}
}
USB.print("\n");
delay(1000); // wait some time each loop
}
Read all blocksCode:
