HAnix-diy - Public: Huzzah32 - RFID base module

A basic circuit to play with RFID and the Huzzah32.
It can be used as base for other projects.
The idea is just to have a Huzzah32 connected to a MF RC522 board and a small display, reading an RFID card/tag and showing it on the display.
The RC522 reader uses tags at 13.56 Mhz.

Shopping list

The basic component is the Huzzah32 board, the display board and the MF RC522 board.

Huzzah 32

The Rfid-RC522 board

Huzzah32 Oled display 128 x 64

Development system

The development system is based on Arduino.
Here some settings :

Install Silicon Labs USB to UART bridge
Arduino IDE 1.8.10

Be sure to have installed these boards :

Adafruit AVR Boards (1.4.13)
Adafruit SAMD boards (1.5.7)
Manually install EspressIf Arduino Esp32

Be sure to have installed these libraries :

ArduinoBLE (1.1.2)
Adafruit GFX Library (1.6.1)
Adafruit SSD1306 (2.0.2)
Manually install RFID library

In the preferences have these additional URLs :

In the Tools setting :

select board :

Adafruit ESP32 Feather
Upload speed : 921200
Port /dev/ttyUSB0 (or the USB port available)
Programmer : USBtinyISP

Connections

The OLED Feather Wing is placed over the Huzzah32 (Piggy-bag).
The RC522 board is hooked to the Huzzah 32 as :

RC522 Vcc <--> Huzzah32 3.3V
RC522 Gnd <--> Huzzah32 Gnd
RC522 MISO <--> Huzzah32 MISO
RC522 MOSI <--> Huzzah32 MOSI
RC522 SCK <--> Huzzah32 SCK
RC522 SDA <--> Huzzah32 GPIO 12
RC522 RST <--> Huzzah32 GPIO 13

Here a schematic that illustrate the connections :

Code

Mainly juts initialize the SPI and call the init call for the RC522 library.

So, include :
......................
......................
#include <SPI.h>
#include <Wire.h>
#include <MFRC522.h>
#include <Adafruit_GFX.h>
#include <Adafruit_SSD1306.h>

// Mifare TC522 settings
#define SS_PIN 12
#define RST_PIN 13

MFRC522 mfrc522(SS_PIN, RST_PIN); // Create MFRC522 instance.

......................

So in the setup part of the sketch :

...............................
...............................
Serial.begin(115200);
Serial.println("\n\nRFID Reader 1.0 - first prototype");

initDisplay();

// Initialize SPI
SPI.beginTransaction(SPISettings(1000000, MSBFIRST, SPI_MODE0)); //set parameters
SPI.begin(); // init SPI
delay(10);
mfrc522.PCD_Init(); // Init MFRC522 card
...............................

...............................

and in the loop just check if a card is detected and read it.
In the example below simply dump the content in the serial monitor.

...............................
...............................
// Look for new cards
if ( mfrc522.PICC_IsNewCardPresent()) {
Serial.println("Card present");
// Select one of the cards
if ( mfrc522.PICC_ReadCardSerial()) {
Serial.println("Data available");
// Dump debug info about the card. PICC_HaltA() is automatically called.
mfrc522.PICC_DumpToSerial(&(mfrc522.uid));
}
}
...............................
...............................

Examples

Here an example of dumping the content of a RFID card (from the serial monitor)
