مشکل در راه اندازی ماژول rfid rc522
با عرض سلام و خسته نباشید
من این ماژول رو از سایت خریدم ولی متاسفانه موفق به راه اندازی نشدم :D
هر کاری هم میکنم نمیشه که نمیشه
ماژول کارت خوان آر اف آی دی با قابلیت خواندن و نوشتن - RFID Reader & Writer RC522
سیم بندیم به این شکل هست
کد:
MOSI: Pin 11 / ICSP-4
* MISO: Pin 12 / ICSP-1
* SCK: Pin 13 / ISCP-3
* SS/SDA: Pin 10
* RST: Pin 9
و این هم کدی که اجرا میکنم
کد:
#include <SPI.h>
#include <MFRC522.h>
#define RST_PIN 9 // Configurable, see typical pin layout above
#define SS_PIN 10 // Configurable, see typical pin layout above
MFRC522 mfrc522(SS_PIN, RST_PIN); // Create MFRC522 instance.

کد های دیگر هم امتحان کردم نشد که نشد
فکر می کنم مشکل از ماژول باشه
