Arduino SAMD WiFiNINA firmware RGB led

Importa e usa la libreria WiFiNINA

Questa libreria consente di utilizzare le funzionalità di Arduino UNO WiFi Rev.2,  Arduino NANO 33 IoT,  Arduino MKR 1010 e Arduino MKR VIDOR 4000 WiFi. Può fungere sia da server che accetta le connessioni in entrata che da client che ne effettua quelle in uscita. La libreria supporta le crittografie WEP, WPA2 Personal e WPA2 Enterprise. Questa libreria supporta tutti gli stessi metodi della libreria WiFi originale più il file connectSSL(). La libreria è molto simile all’Ethernet e alla libreria WiFi e molte delle chiamate di funzione sono le stesse.

Download

Arduino IDE WiFiNINA library download

Puoi semplicemente scaricare WiFiNINA lib dal repository delle librerie.

Ora hai anche una nuova voce di menu, WiFi101/ WiFiNINA firmware.

Verificare il firmware

È essenziale che la versione WiFiNINA e il chip NINA-W10 abbiano la versione corretta; puoi verificarlo con uno sketch di esempio che puoi trovare in
File --> Examples --> WiFiNINA --> Tools --> CheckFirmwareVersion

Arduino IDE WiFiNINA Firmware updater sketch

aprilo e caricalo.

    Serial.println("   issues or failures.");
  }
}

  // do nothing
}

Se hai la versione firmware errata, viene visualizzato questo messaggio.

WiFiNINA firmware check.

Firmware version installed: 1.3.0
Latest firmware version available : 1.4.2

Check result: NOT PASSED
 - The firmware version on the module do not match the
   version required by the library, you may experience
   issues or failures.

Aggiornare il firmware

Se hai la versione del firmware sbagliata, devi caricare l’ultima.

Per farlo, devi usare un altro sketch di esempio da
File --> Examples --> WiFiNINA --> Tools --> FirmwareUpdater

dopo aver aperto lo sketch fai l’upload.

Ora puoi fare clic su WiFi101/ WiFiNINA firmware updater.

Seleziona la porta del dispositivo corretta, prova la connessione di prova; se tutto è a posto, selezionare l’ultima versione del firmware e fare clic su Aggiorna firmware.

Come puoi vedere, puoi anche aggiungere un dominio certificato al NINA-W101, in modo che diventino sicuri.

Semplice connessione WiFi con WiFiNINA

Ecco un semplice sketch per connettere il tuo dispositivo con WiFiNINA.

/*

 * Connect to WiFi

 */
#include <WiFiNINA.h>

const char* ssid     = "SSID";         // The SSID (name) of the Wi-Fi network you want to connect to
const char* password = "PASSWORD";     // The password of the Wi-Fi network

void setup() {
  Serial.begin(115200);         // Start the Serial communication to send messages to the computer
  delay(10);
  Serial.println('\n');

  WiFi.begin(ssid, password);             // Connect to the network
  Serial.print("Connecting to ");
  Serial.print(ssid); Serial.print(" .");

  while (WiFi.status() != WL_CONNECTED) { // Wait for the Wi-Fi to connect
    delay(1000);
    Serial.print('.');
  }

  Serial.println('\n');
  Serial.println("Connection established!");
  Serial.print("IP address:\t");
  Serial.println(WiFi.localIP());         // Send the IP address of the ESP8266 to the computer

Gestisci il Led RGB con WiFiNINA

La libreria WiFiNINA contiene anche il codice per gestire i LED RGB presenti sul dispositivo MKR, e utilizza il protocollo SPI dell’IC per inviare il valore ai tre pin Rosso, Verde e Blu.

Nella libreria, la gestione del pin è racchiusa con un comando clone di digitalWrite e un clone di analogWrite.

Ecco uno schizzo con digitalWrite che cambia il colore

#include <WiFiNINA.h>
#include <utility/wifi_drv.h>

#define RGB_LED_GREEN 25
#define RGB_LED_RED 26
#define RGB_LED_BLUE 27

void setup()
{
	WiFiDrv::pinMode(RGB_LED_GREEN, OUTPUT); //GREEN
	WiFiDrv::pinMode(RGB_LED_RED, OUTPUT); //RED
	WiFiDrv::pinMode(RGB_LED_BLUE, OUTPUT); //BLUE
}

uint8_t currentLedCounter = 0;

uint8_t leds[] = {RGB_LED_GREEN, RGB_LED_RED, RGB_LED_BLUE};

void loop()
{
	WiFiDrv::digitalWrite(leds[currentLedCounter], LOW);
	currentLedCounter++;
	if (currentLedCounter>2){
		currentLedCounter = 0;
	}
	WiFiDrv::digitalWrite(leds[currentLedCounter], HIGH);
	delay(1000);
}
