Hello guys, I recently acquired an MKRFOX1200 board. I was tinkering about with it when I decided to hook up an SPI interface. My choice was an RC522 rfid card reader.
After hooking up the MOSI, MISO & SCK pins as labelled on the MKRFOX, I modified a dumpInfo example with my respective SS & RST on the CCT. Now after uploading the code, I indeed got the RC522 Hex Address, but the reader wont read any tags i placed on the reader. What could I be doing wrong in this setup?
The SPI.h library under the SAMD folder is available but somehow not invoked.
#include <SPI.h>
#include <MFRC522.h>
#define RST_PIN 5 // Configurable, see typical pin layout above
#define SS_PIN 4 // Configurable, see typical pin layout above
MFRC522 mfrc522(SS_PIN, RST_PIN); // Create MFRC522 instance
void setup() {
Serial.begin(9600); // Initialize serial communications with the PC
while (!Serial); // Do nothing if no serial port is opened (added for Arduinos based on ATMEGA32U4)
SPI.begin(); // Init SPI bus
mfrc522.PCD_Init(); // Init MFRC522
delay(4); // Optional delay. Some board do need more time after init to be ready, see Readme
mfrc522.PCD_DumpVersionToSerial(); // Show details of PCD - MFRC522 Card Reader details
Serial.println(F("Scan PICC to see UID, SAK, type, and data blocks..."));
}
void loop() {
// Reset the loop if no new card present on the sensor/reader. This saves the entire process when idle.
if ( ! mfrc522.PICC_IsNewCardPresent()) {
return;
}
// Select one of the cards
if ( ! mfrc522.PICC_ReadCardSerial()) {
return;
}
// Dump debug info about the card; PICC_HaltA() is automatically called
mfrc522.PICC_DumpToSerial(&(mfrc522.uid));
}
