Имеется Arduino UNO
стандартный скетч WebServer полностью устраивает только необходимо добавить туда чтобы в вебпанели выводилась информация с rfid(RC522) считывателя, а именно Card UID(номер карты), подскажите пожалуйста как это можно сделать? Спасибо!
/*
Web Server
A simple web server that shows the value of the analog input pins.
using an Arduino Wiznet Ethernet shield.
Circuit:
* Ethernet shield attached to pins 10, 11, 12, 13
* Analog inputs attached to pins A0 through A5 (optional)

/* * ---------------------------------------------------------------------------- * This is a MFRC522 library example; see https://github.com/miguelbalboa/rfid * for further details and other examples. * * NOTE: The library file MFRC522.h has a lot of useful info. Please read it. * * Released into the public domain. * ---------------------------------------------------------------------------- * Example sketch/program showing how to read data from a PICC (that is: a RFID * Tag or Card) using a MFRC522 based RFID Reader on the Arduino SPI interface. * * When the Arduino and the MFRC522 module are connected (see the pin layout * below), load this sketch into Arduino IDE then verify/compile and upload it. * To see the output: use Tools, Serial Monitor of the IDE (hit Ctrl+Shft+M). * When you present a PICC (that is: a RFID Tag or Card) at reading distance * of the MFRC522 Reader/PCD, the serial output will show the ID/UID, type and * any data blocks it can read. Note: you may see "Timeout in communication" * messages when removing the PICC from reading distance too early. * * If your reader supports it, this sketch/program will read all the PICCs * presented (that is: multiple tag reading). So if you stack two or more * PICCs on top of each other and present them to the reader, it will first * output all details of the first and then the next PICC. Note that this * may take some time as all data blocks are dumped, so keep the PICCs at * reading distance until complete. * * Typical pin layout used: * ----------------------------------------------------------------------------------------- * MFRC522 Arduino Arduino Arduino Arduino Arduino * Reader/PCD Uno Mega Nano v3 Leonardo/Micro Pro Micro * Signal Pin Pin Pin Pin Pin Pin * ----------------------------------------------------------------------------------------- * RST/Reset RST 9 5 D9 RESET/ICSP-5 RST * SPI SS SDA(SS) 10 53 D10 10 10 * SPI MOSI MOSI 11 / ICSP-4 51 D11 ICSP-4 16 * SPI MISO MISO 12 / ICSP-1 50 D12 ICSP-1 14 * SPI SCK SCK 13 / ICSP-3 52 D13 ICSP-3 15 */ #include <SPI.h> #include <MFRC522.h> #define RST_PIN 9 // #define SS_PIN 10 // 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 ShowReaderDetails(); // Show details of PCD - MFRC522 Card Reader details Serial.println(F("Scan PICC to see UID, type, and data blocks...")); } void loop() { // Look for new cards 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)); } void ShowReaderDetails() { // Get the MFRC522 software version byte v = mfrc522.PCD_ReadRegister(mfrc522.VersionReg); Serial.print(F("MFRC522 Software Version: 0x")); Serial.print(v, HEX); if (v == 0x91) Serial.print(F(" = v1.0")); else if (v == 0x92) Serial.print(F(" = v2.0")); else Serial.print(F(" (unknown)")); Serial.println(""); // When 0x00 or 0xFF is returned, communication probably failed if ((v == 0x00) || (v == 0xFF)) { Serial.println(F("WARNING: Communication failure, is the MFRC522 properly connected?")); } }
Не вижу, чтобы вы пытались обьединить два скетча. Почитайте правила форума, никто за вас это делать не будет, здесь помогают тем, кто пытается решать проблемы сам.
И еще - имхо, сама идея выводить UID карты в Вебпанель - не слишком удачная
